This episode covers an herb of the world: horseradish or Armoracia rusticana, which is, of course an herb and a food. It has been used for over 2,000 years for respiratory and urinary issues as well as for culinary purposes. We are going to explore all of these aspects. And, as usual, we will explore all the intricacies of this herb as well as an explanation of its category. Each episode of the podcast will go into great depth about a single herb or formula. Besides covering the basics of herbology including category, and functions, we will explore the history, quality, science, pharmacology, evidence, and any potential interactions of each herb. And then there is always something a little quirky about an episode. In this episode, we are going to look at how Chinese medicine regards fats in our diet. Please join us as we find out more about this fascinating herb horseradish or Armoracia rusticana!

Speaker 1 (00:03):
That angelic Sperver.

Speaker 2 (00:10):
Welcome to today's episode of Sperbs Herbs. It is episode
seventy two and we are going to be talking about
horse radish or amasier resticana.

Speaker 1 (00:24):
Today's episode, we'll be.

Speaker 2 (00:25):
Looking at another traditional Western herb as well as another
Western herb with culinary uses, horse radish. As always, we
will do our deep dive into this herb and look
at its traditional uses, does it have any Chinese medical functions,
and its preparation interactions and cautions, And as usual we

(00:47):
will be adding something a little different. We're going to
discuss how Chinese medicine regards fats in our diet. It's
going to be another interesting, splunky mission into the depths
of herbdom. Please keep listen. Did you know that I've
written a couple of books. The first book is Integrative Pharmacology,
combining modern pharmacology with integrative Medicine. This is a pretty

(01:10):
thorough book discussing pharmaceuticals, what they are used for, how
they work, and how they may interact with other drugs,
herbs and supplements. It is the perfect reference book for
all acupuncturists, herbalists, chiropractors, natural paths, and really any integrative practitioner,
but it is also perfect for anyone.

Speaker 1 (01:30):
It goes in depth, but.

Speaker 2 (01:31):
It is easy to read and has difficult terminology bolded
with definitions on the same page. This is not only
a great book explaining pharmaceuticals, it is also available at
an amazing price. Is available for ten percent off its
regular price, and you get assigned by me the author
for just sixty seven dollars and forty five cents. My

(01:54):
second book, written with an amazing insurance effort, Tiffany Anderson Hefner,
is called Plain a Game, A step by step approach
to accepting insurance as an acupuncturist. This is the perfect
book for any acupuncturers who wants to or is contemplating
accepting insurance. They give step by step advice at every

(02:15):
part of the insurance game, from getting set up, through
the patient encounter and of course getting paid, all uneasy
to digest language, honest advice and lots of handholding through
the process.

Speaker 1 (02:28):
And you guessed.

Speaker 2 (02:29):
It is also temperson often signed by one of the authors,
me all for twenty six dollars a ninety eight cents.
You can get either or both of these books at
the shop at www dot sperbserbs dot com. That's www
dot sperbserbs dot com, s p e r B s

(02:49):
h e r bs dot com. So I am in
the middle of a new of courses called integrative nutrition
where we take a serious biochemical look at various aspects
of nutrition and related topics, look at the Chinese medical

(03:11):
approaches to these aspects, and then take a deep dive
into various supplements that may help or impact these aspects
of nutrition. One of those courses was fat Fats and
Chinese Medicine, as I actually fatty acids in Chinese medicine
as our something a little different today, I thought we

(03:33):
would spend a little time discussing how Chinese medicine views
fats and lipids. And if you want to learn more

Speaker 1 (03:49):
All one word.

Speaker 2 (03:52):
So Healing with Whole Foods Asian Traditions of Modern Nutrition
by Paul Pitchford. It is probably the most plead book
on the application of Chinese medicine to diet nutrition in
the English language. Having said that many experts believe it
is not firmly based on traditional Chinese medical theory and
has a lot of modern nutritional concepts mixed in. Not

(04:14):
necessarily a good or bad thing, but we need to
know about that aspect. But I kind of like that
aspect of it. In this book, he says, fat consumption
supports the yin principle and creates a sense of security, heaviness,
and a slowing grounding influence. Fats build the tissues, enhance

(04:35):
the fluid metabolism, and direct nutrients into the nervous system.
Then the predominantly yin aspect of fact gradually changes into
a young, physically energizing.

Speaker 1 (04:47):
And warming quality.

Speaker 2 (04:51):
This is why fats, whether from oils, nuts, seeds, or
animal products, are so highly valued. People like to feel secure,
to slow down, and to have ample energy and warmth.
From a therapeutic standpoint, those who benefit most from a
moderate amount of fats are thin, dry, nervous, unproductive, or

(05:15):
lacking a strong sense of connection with the earth. In fact,
in several Asian traditions, herbs prescribe for the flighty dry
type of person are mixed with an oil such as sesame,
But there are some precautions fats and oils should be
used sparingly by those who are overweight, slow, mentally or

(05:35):
emotionally heavy, materialistic, overheated manifested by red face, bloodshot eyes,
yellow tongue coating, some kinds of high blood pressure, a
tendency to feel too hot, or who have damp symptoms
can be a yeast, yeast overgrowth, edema, tumors, cysts, and

(05:56):
excess body weight. Pitchford has a footnote in this section.
The liver plays a central role in fat metabolism and
traditional Chinese physiology. Is also the seed of the emotions
and strongly influences the eyes, tendons, and ligaments. Furthermore, the

(06:17):
liver acupuncture meridian passes through the head and around the
surface of the genitalia. Pain and spasms ensue when the
liver loses its ability to support smooth chief flow. This
implies too little or too much, or just disordered fat
intake can affect any of these aspects of the liver.

(06:42):
Bob Flaws, who we quote quite often, is he contributed
to my book The Integrative Pharmacology and just has probably
written more books in Chinese medicine than anyone else I'm
aware of in English.

Speaker 1 (06:55):
Anyways.

Speaker 2 (06:56):
So in his book The Dow of Healthy Eating, it
says Chinese medicine I identifies a number of especially dampening foods.
These include such sweet and sourw foods as citrus, fruits
and juices and tomatoes, such concentrated sweets as sugar, molasses,

(07:17):
and honey, and also highly nutritious foods such as wheat,
dairy products, nuts, oils, and fats. Highly nutritious food nutritious
foods have more flavor whey than chi. This context, chi
means the light, airy, aromatic, and young part of a food,

(07:39):
whereas whey, literally meaning taste, refers to a food's heavier,
more substantial, more nourishing Yin aspects, all foods are a
combination of cheat and whey, and here again we see
Chinese medicine's emphasis on balance. Highly nutritious foods, such as

(08:03):
dairy products, meats, nuts, eggs, oils, and fats are strongly
capable of supplementing the body's yin fluids and substances. However,
in excess they generate a superabundance of body fluids, which
become pathologic dampness. Although this may appear to be a paradox,

(08:26):
it has to do with healthy yin in excess becoming
evil or pathological yin or dampness, phlegm, and turbidity. So
that was a quick introduction to the Chinese medical view
of fats and lipids. Let's get into our herb for today.

(08:46):
Today we are going to be talking about horse rash,
which comes from the Rasciassia or mustard family. The species
is Rassier resticana, and the medicinal part is the root
or rhizomes or rhizomes are the kind of rootlets coming
off of the route. Other names are Cochlearia, army army assier,

(09:09):
army Asia, Pathafolia, gilib gilib referring. Of course, as we've
we've mentioned many times to the biologists who classified it
can be Mountain, Radish, rad coal, ray Ford, Grand ray Fort,
Great ray Ford, Cranson, red coal, and mirror Redditch, which

(09:31):
is German. And generally I don't get into all that
some of this was was I think Rayford is also
is French. I don't usually get into all the different
I mean there, I mean, where do you stop when
you start talking about all the different language translations. But
there's a particular reason why we're talking about me or redditch,
and we're going to talk about it just a second,

(09:53):
so hang on.

Speaker 1 (09:54):
That's why I brought up the German here.

Speaker 2 (09:57):
Before we get into that, let's talk about the Brasciassier family. So,
according to Petrozilla Petrouzello, the Brasciassia family, formerly called Crucifrae,
is commonly known as the mustard family of flowering plants.
It includes three hundred and thirty eight genera and thirty

(10:18):
seven hundred species. Can depending on the source, you're gonna
get different numbers here. So like I had one source
that said over four thousand species, So this is Petrouzello
saying there's thirty seven hundred species, but they're you know it.
Depending on how things are specifically done, that changes. So
it includes three hundred and thirty a genera and thirty

(10:39):
seven hundred species, many of which are well known vegetables
and spices. These include cabbage, broccoli, Brussels sprouts, all the
all kids favorites are my favorites.

Speaker 1 (10:49):
I love this these vegetables.

Speaker 2 (10:51):
But kids hate them generally, and Brussels sprouts, kale cole, robbie, turnip, rudabaga, radish, horse, radish,
and white mustard, and there are also several ornamentals in
this family, so you might see them as picturesque flowers
in gardens. The plants in this family are usually herbs,

(11:14):
which may be annuals, biennials, or perennials.

Speaker 1 (11:18):
The leaves are mostly.

Speaker 2 (11:19):
Simple and arranged alternatively, and many are peppery and taste.
The flowers are in the form of a cross otherwise
known as cruciform, with four petals and four sepals.

Speaker 1 (11:33):
They are usually white, yellow.

Speaker 2 (11:35):
Or lavender, so not a whole bunch of variety in
the coloring of these.

Speaker 1 (11:43):
Horse riders.

Speaker 2 (11:44):
Has been cultivated since antiquity. It was first mentioned in
diascaratees day Materia Medica, written between fifty and seventy c.
Pliny's Natural History also discussed it seventy seven CE, so
very early. About two thousand years old. Over two thousand
years old or no, about two thousand years old. We're

(12:06):
getting there, not quite two thousand. Both roots and leaves
were used as a traditional medicine during the Middle Ages.
George Washington and Thomas Jefferson both discussed it in accounts
of their gardens. Native Americans used it to stimulate the glands.
Stave off scurvy as a diaphyratic treatment for the common cults.
So this is an interesting one.

Speaker 1 (12:26):
Scurvy.

Speaker 2 (12:27):
So remember scurvy is a lack of vitamin C. And
what we're going to find out is that horse rash
is actually quite rich in vitamin C. So that makes
perfect sense to stave off scurvy. Wright says the common
name horse radish may be a derivation of the German
term mireditch, which means more radish or stronger radish. The

(12:52):
English may have confused the term merr with that of
mayor or mar thinking that the name referred to a horse.
That's where they think the name horse ratsh came from.
Is that it's a misinterpretation of German. So both you know,
our language is made up of a lot of those.

Speaker 1 (13:10):
Sort of things.

Speaker 2 (13:13):
There are lots of culinary uses of horse radish, of course,
according to Wikipedia. Again, I have to mention I do
use Wikipedia occasionally. I do not like it as a
as a major source. I definitely don't use it for
anything scientific, but I think for some broad overviews, I
think it's fine, And that's really what we're talking about here.

(13:34):
So according to Wikipedia, the distinctive pudgeon. Taste of horse
ratish is from the compound allele isothiocyanate. Upon crushing the
flesh of horse radish, the enzyme myrosinase mirosinase is really
any remember anything with an ace in the end, as

(13:54):
is indicative of an enzyme. That is, that means it's
an enzyme. Some eurosinase is released and acts on the
glucosinolites synagrine and gluco nasterton, which are precursors to the
allele isothias cyanate. The alletle isocianate refer serves the plant

(14:17):
as a natural defense against herbivores. Since a litle isothia
thiocyanate man, I'm gonna get it, saying that it is
harmful to the plant itself, it is stored in the
harmless form of the glucosinolate Glucosinolate separate from the enzyme
mirror neurocinase. When the animal choose the plant, the alletle

(14:40):
isothia cyanate is released, repelling the animal. A little isothia
cyanate is an unstable compound degrading over the course of
days at thirty seven degrees or ninety nine degrees fahrenheit,
it is thirty seven degrees I should say thirty seven
degrees celsius or ninety nine degrees fahrenheit. Because of this instability,

(15:02):
horse radish sauce sauces lack the pungency of the freshly
crushed root.

Speaker 1 (15:10):
Cooks may use the terms.

Speaker 2 (15:11):
Horse rash or prepared horse rash horse radish to refer
to the mashed or graded root of the horse radish
plant mixed with vinegar. Prepared horse radish is white to
creamy beige in color. It can be stored for up
to three months under refrigeration, but eventually will darken, indicating

(15:31):
less flavor. The leaves of the plant are edible, either
cooked or raw when young, with a flavor similar but
weaker than the roots and on passover. Many Ashkenazi Jews
use grated horse rash as a choice for morale or
bitter herbs at the passover satar. Outside Japan, the Japanese

(15:55):
condiment with sabi, although traditionally prepared from the true asabi
plant was Sabia japonica, is now usually made with horse
rash due to the scarcity of the wasabi plant. The
Japanese Botanical name for horse rash is Seo wasabi or
Western wasabi. Both plants are members of the family Brasciassier,

(16:16):
so they're both in the same family. So their cousins
basically is what we're talking about here. So what are
some traditional uses of horse rash? So according to Gruenwald,
Grunwald is is at all I should say Gruenwald and
his team is the PDR for herbal medicine is a

(16:37):
giant book on herbal medicines and with a little bit
of a scientific edge to it, and so that's a
big book. So according to them, horse rash is approved
by commission E for cough, bronchitis and infections of the
urinary track. Now we've talked about commission E in previous
Sperbs Herbs episodes. This was a big commission that was

(16:59):
created by Europe in Europe to the European Union to
study herbs and to see which ones would be are
are actually doing what they're supposed to be doing and
can be sold without much restriction, and those that are
not and may be restricted by law. Now this is
coming from the nineties, This is quite a bit, quite

(17:20):
old by today's standard, but still when commissioner says something
most people will. It has not been updated in decades,
so it's not up to date, but it still holds
a little bit of When something's approved by commissioning, that
holds a little something something when.

Speaker 1 (17:36):
It comes to herbs.

Speaker 2 (17:38):
So and in that case, commissioner approved it for coffin
bronchitis or infections and infections of the urinary tract. Unproven
uses include inflammation of the respiratory tract and as support
of therapy for infections of the urinary tract. Externally, the
drug is used for inflammation of the respiratory tract and

(18:00):
for hyperremic treatment for minor muscle eggs.

Speaker 1 (18:04):
So hyperremic means to bring redness.

Speaker 2 (18:07):
It really means too much redness, but in this case
what it means is is for hyperremic treatment means to
bring blood flow from minor muscle eggs. In folk medicine,
horse rash is administered for influenza, respiratory elements, digestion, gout, rheumatism,
and liver and gallbladder disorders, and homeopathically is used to

(18:32):
treat eye inflammations, upper respiratory tract inflammations, and upper abdominal colic.
Colic pain, pain that comes and goes. Web MD says
something similar, saying horse rash might help fight bacteria and

(18:52):
stop spasms. People use horse rash for urinary tract infections
to UTIs, colic, gout, and many other conditions, but there's
no good scientific evidence to support their uses, so that's
you know, interesting commission he said there was some scientific evidence,
though I'm being honest, the level of scientific governance for
commissioning is probably not as high as it would be today,

(19:14):
but still right. Another source says early physicians and healers
would recommend horse rash for everything from a sore throat
to digestive upset. During the Middle Ages, the leaves and
roots were used for treating asthma, arthritis, cancer, and twothaches.
Rubefacient and diuretic properties were ascribed to horse radish. So

(19:38):
rubiphatient basically means a substance applied externally that produces redness
of the skin, So that makes sense. Ruby is red
and patient and you know, bringing red to the skin basically,
and diuretic means of course, urination, promoting your nation. When

(19:58):
the ground root was made into a poultice and applied
to the skin, it would cause heat and irritation with lend,
which lends credence to the idea that it can stimulate
the circulatory system. The leaves were also made into poultices
and applied to the chest to help with colds and congestion.

(20:20):
Tonics were used as an expectrant for coughs, sore throats,
and horseness. Once the plant became established in North America,
Native Americans utilized it for toothaches and menstrual cramps.

Speaker 1 (20:34):
And what's very.

Speaker 2 (20:35):
Interesting is horse rash still plays actually a really important
role in the medical field today. The enzome horse rash
peroxidase HRP is a useful tool for detecting antibodies in
the molecular biology field, and it is derived it has
grown and then extracted from horse rash. So it's actually

(20:55):
really interesting. Research is being conducted on the herb to
explore the possible that the compounds it holds may help
prevent cancer, So sam anti cancer properties in there as well.
Let's talk about dosage in preparation. WebMD says as medicine,

(21:16):
there isn't enough reliable information on what an appropriate dose
of horse rash may might be. Keep in mind that
natural products are not always necessarily safe, and dosages can
be important. That's WebMD being fairly conservative. Homes, so we're
gonna talk a lot about homes, and just a little bit.
In fact, in a couple of pages, we're gonna get

(21:36):
into homes quite a bit a couple slides. Holmes wrote
the Energetics of Western Herbs, and I use that often
when I'm looking at Western herbs and how they might
be in Chinese medicine. And so he does that kind
of conversion, and it's a big book. It's two volume book,
and you know, it's a pretty good book. So he
says dosing is fifteen to twenty drops, up to three

(21:58):
milli liters of fresh juice, two to four grams of
graded root, two to four grams of cold water vinegar
and fusion. And for tinctures zero point two to five
to point five millilters at one to two strength in
thirty percent ethanol, which I'm not going to get into here,

(22:20):
but if you prepare tinctures, that all is very important
information for the for the dosing. The PDR for herbal medicines,
as I mentioned, that's from Gruenwald at all, and his
team says to use fresh or dried root that has
been cut or ground, freshly pressed juice, or other galenic

(22:42):
preparations for internal and external applications.

Speaker 1 (22:45):
So first of all, I really I just want.

Speaker 2 (22:48):
To mention galenic preparations. That is referring to Galen, who
we've actually talked about again in previous for observes. As
you know, I I think Western or Eastern you'd be
hard pressed to find many doctors who've had as profound
an influence on medicine as Galen, and yet he's not.

(23:10):
He's incredibly well known by medical historians, but not very
well known in the population. I think he was far,
far more powerful and had more of an impact on
Western medicine than Hippocrates. But everyone knows Hippocrates and not
everyone knows Galen. So anyways, that's referring to Galen. So

(23:32):
it says the average dose for internal use is twenty
grams of fresh root. For external use, ointments and gels
with a maximum two percent mustard oils may be used.
And then Holmes again that's the energetics of Western herbs,
says dosage is six to fourteen grams for an infusion

(23:52):
two to fourmula leaders at one three strength. A's sixty
percent ethanol and one to two drops of essential oil
and a jail cap top with some olive oil. He
says that infusion should be kept covered to retain the
essential oils. So that's that's an interesting one. So it
says one to two drops of essential oil. If I'm

(24:13):
not mistaken, we're gonna find out that one of the
warnings has never used the essential oil because it's quite toxic.
And I want to talk about that, but we'll talk
about that when we get into the cautions. So let's
talk about Chinese medical actions. So Chinese Nutrition dot Org
says it is pungent and hot, and there's the lung,

(24:33):
stomach spleen, bladder, and kidney. That's a lot of meridian stanter.
It's five of them and it tonifies yong. Makes sense.

Speaker 1 (24:42):
This is very warming.

Speaker 2 (24:44):
In terms of traditional Chinese medicine. Horse rash is known
for its ability to tanify yng. It also helps to
promote cheese circulation, disperse cold, resolve damness, expel wind, and
resolve phlegm. Horse rash is specific good for treating wind
damp cold, which is very specific. Wind damp cold b

(25:06):
or obstruction disorder is a whole class of orders, of
which a lot of those like osteoarthriis, some of those
arthrities will fall into play, So that that's interesting here. Rheumatism,
as we mentioned earlier, in traditional actions, so Holmes, as

(25:27):
I mentioned, that's the Inenerjets of Western Herbs. I actually
has an entry on horse raction in his book The
Enerjets of Western Herbs, a material Medica integrating Western and
Oriental herbal medicine traditions, and he says it is very pungent, aromatic,
hot and dry, and enters the lung spling, kidney, and

(25:48):
vladim meridians in addition to several traditional functions. Now he
says these are traditional functions. These are not traditional functions
as we would see in like a translation of the
Chinese Material medical or anything, but they come close. They're
in the ballpark of it. So here's there's a lot
of them. So here's what he says.

Speaker 1 (26:04):
It does.

Speaker 2 (26:05):
It warms the stomach, intestines, promotes digestion, and resolves mucus,
damp reduces accumulation, resolves dys biosis.

Speaker 1 (26:14):
And relieves bloating.

Speaker 2 (26:16):
So dyspiosis is a term that indicates an imbalance in
bacterial composition, changes in bacterio metabolic activis, or changes in
bacterial distribution within the gut. So it could be the
biome the microbiome within the gut as well. So that
was one of seven. All of that was one line.

(26:38):
So the next one is warms the lungs, promotes expectoration
and resolves phlegm diffuse lung chi opens the sinuses and
relieves coughing and wheezing. It warms the exterior, stimulates the muscles,
dispels wind, damp cold and relieves pain. Promotes urine nation,

(27:00):
drains water and relieves edema, promotes menstruation, expels the afterbirth
and stops discharge. It reduces infection, eliminates parasites and antidotes poison,
promotes tissue repair, reduces contusion, and benefits the skin. Confusion

(27:20):
is a bruise, and it inhibits the thyroid and restores
the pancreas. Now those are very much not Chinese functions
because that is, the thyroid and the pancreas are not
directly discussed in Chinese medicine, but it's an interesting overlay on.

Speaker 1 (27:40):
All of this.

Speaker 2 (27:41):
So what horse rash can do not turum buying it.

Speaker 1 (27:44):
But it's interesting.

Speaker 2 (27:49):
So let's talk about some comparisons of this herb to
other herbs. While focusing more on the taste of horshash,
Wright says, what's right was an issues. I haven't explained
what book this is. This is a book on horse rash.
I'm put out by some herbal society and it was
it was in twenty ten, twenty eleven. They made the

(28:10):
horse rash the herb of the year, so they wrote this.
They have this book that's available on PDF. I can
certainly if you want it, I could send me an
email and I can send you a link to it. Actually,
it's in the bibliography as well, if you get the bibliography.
So Wright says, with sabi or with sabi Japanica and
the horse rash tree Maringa, oli Ephra, lamb, or other

(28:33):
plants with taste similar to that of horse radish, was
sabi sometimes called Japanese horse radish, can be found growing
wild in Japan and Siberia. Advocates with sabi claimed that
it is superior to horse rash because of its pungent,
hot flavor. Others argue that horse rash has more heat,

(28:55):
but sabi is often used as a substitute for horse radish,
but strangely, horse rash is often dyed green and uses
a cheaper imitation of wasabi. See I just want to imagine.
I'm a huge fan of sushi. I've been making sushi, god,
probably for thirty years. I love sushi, and I don't
think I've ever tasted real wasabi. Maybe i'd been at

(29:19):
some good sushi restaurants. Maybe I have there, and I
don't remember. Almost all of the wasabi I've had, and
I use it a lot. I love it. Is that
green horseradish stuff. All that stuff you get at most
sushi restaurants is horse rash, not wassabi. The roots of
these herbs talking about wassabi and horse rash different than
Wassabi has green roots, while horse rash has white roots.

(29:44):
The roots of m oli afa, more commonly known as
horseradish tree or oil of bend tree, can be ground
up in substituted for horse rash, although the flavor is
not quite as pungent. This plant is native to Arabia
and India, and Holmes says scurvy grass or Cochlearia officionalis

(30:10):
l has a similar profile to horse tratish root similar
in constituents and qualities to horse raish. Scurvy grass is
a pungent, warm digestive stimulant for gastro intestinal dyspepsia, an
expectant and bronchial relaxant for chronic bronchitis and asthma, and

(30:30):
a lymphatic stimulant for lymphatitis inflammation of the lymph noodes.
Secondary uses include rheumatic conditions, biliary and urinary stones that
means called bladder and urinary stones or bladderstones, kidney stones,
and leukorea. Lukorea is a white discharge, white vaginal discharge,

(30:55):
so that's where that can scurvy grass can come in
as a comparison to or trash. So the contents according
to right horse thrash is low en calories and rich
in vitamins A and C. Cooking eliminates its nutritional value
and it should be used fresh. Mustard oils are usually

(31:20):
bound in the vacuoles of the plant cells with sugars
as either sinnagrine GLUCOSINELLATEE. I can't say this for glucosinalate
or gluconite. Stertin beta phenolthyl glucosinalate. They are separated from
a membrane bound enzyme called merosinase. We've mentioned this earlier.

(31:43):
The barrier that separates the plant vacuoles. Vacuoles are like
little bubbles basically that store things from The morosinase is
broken down when the skin of the horse thrash root
is ruptured, making way for hydrolysis or splitting the water
of the sugar bonds by the neurocinase, which freeze the

(32:05):
isothio cyanates or mustard oils. The chemical reaction is responsible
for the eye watering heat producing properties of AVRs tocana.
The reaction only occurs if the skin is ruptured and
its effects are short lived. An ether extract of a
ground root yields seventy six to eighty percent of allele

(32:28):
isothiocyanate and sixteen to eighteen percent beta phenol ethyl isothia thiocyanate.
The essential oil of a horse rash is toxic and
should be treated with extreme caution. That's where we get
that from, and that's why when Holmes was mentioning the
use of essential oil, I'm a little uncomfortable and I'll

(32:51):
tell you why.

Speaker 1 (32:51):
I'm a little bit uncomfortable.

Speaker 2 (32:54):
Because mustard oils are wet produced mustard gas, and mustard
gas is a toxic agent. It was used in World
War I think it was the most commonly used toxic
gas used in World War One, and then it was
banned internationally. Mustard gas was so I'm I would be

(33:19):
very hesitant to use essential oils of this and and
and like earlier, we said two percent maximum mustard oil
and anything topical, and that seems fairly reasonable. Anything more
that cost of if you're not familiar with mustard gas,
highly toxic. It basically blisters the skin and most important

(33:40):
when you inhalate, it blisters the lungs. And horrible, horrible, horrible.

Speaker 1 (33:44):
Way to go.

Speaker 2 (33:46):
So yeah, let's be let's be a little bit cautious
on this essentral oil of horsehradish in addition to the
aforementioned mustard oils and its derivatives. Charles another source here
says other important constituents of horse rash include asparagenes asperagenes
which is found in asparagus as well, which is interesting.

(34:08):
I don't know, I don't we didn't mention asparagus as
part of this family. I should probably look that up,
but that's interesting that it's in there. Cumarans, which we've mentioned,
is they're often in herbs and they tend to have
the tendency to be anticoagulant or as some people say,
blood thinning.

Speaker 1 (34:27):
I don't like that term, but there you go.

Speaker 2 (34:31):
So asperagenes asparagenes, cumarins, phenolic acids, and ascorbic acid, scorbic acids.

Speaker 1 (34:39):
Vitamin C. So that makes sense. We already mentioned that.

Speaker 2 (34:44):
So what does the science say about horse rash? So
Charles says, horseharsh has been traditionally used to treat bronchial
conditions and urinary tract infections. Externally, it is applied as
a counter irritant to treat rheumatism and inflammation. Counter irritant
is basically it's that whole I do this thing. For

(35:08):
those of you who are acupuncturist, we know that large
intestine four, which is in between the thumb and the
four and the forefinger I kind of down a little bit,
is a really good point for headaches. And so when
someone has a headache, you can press that point and
it can help a headache. My teacher Marshal Arten Charter
said it only works about forty percent of the people.

(35:30):
That's been my experience, so it doesn't work all the time.
But whenever I do that to someone who has a headache,
and I do that point and I ask them if
they're if their headache feels better, they go yes, but
now my hand hurts.

Speaker 1 (35:42):
And that's sort of.

Speaker 2 (35:43):
The counter irritant sort of thing. Is like, you know,
so you have a spraying wrist and then you slap
them in the face and they don't they forget the risk,
you know, that sort of thing.

Speaker 1 (35:52):
You know, that's a counter inertent.

Speaker 2 (35:54):
Basically, take your mind off of it and put it
somewhere else.

Speaker 1 (35:57):
So there you go.

Speaker 2 (35:58):
So externally applied as a counter inirtant to tree rheumatism
and inflammation. It has antioxidant, antimicrobial, spasmolytic. So antioxidant of
course is against oxidants, which you know is important, that's useful.
Antimicrobiomeans is against bacteria also potentially viruses and parasites and.

Speaker 1 (36:18):
Things like that.

Speaker 2 (36:19):
Spasmolytic means that it literally splits spasms, so it's an
anti spasmodic. Basically, it helps spasms of the muscles, cytotoxic
which means it kills cells and skin, irritant, hyperremic properties
and thus is attributed to the isof and this is

(36:39):
attributed to the isothiocyanates, which makes a lot of sense.
It is claimed to be used to treat general debility, arthritis, gout,
urinary infections, respiratory infections, and fevers. The fresh root is
said to be antiseptic, diuretic, rubefacient, which you mentioned earlier,

(37:02):
stomach acheic which means it's good for stomach aches, stimulant,
and vermifuge which means it kills worms. It is applied
externally as a poultice for infected wounds. Inflammation of the
pleura our threat and plural inflammation of the plural so
the plural it says, applied externally for inflamation of the
plural the plural the lung pleura.

Speaker 1 (37:24):
This is the lining of the lungs.

Speaker 2 (37:25):
So you're you're not You're applying it to the chest
to help inflamation of the plur It's sort of like
putting menthol on your chest. Arthritis and inflammation of the
pericardium that sack around the heart. The roots of horse
rash are also used as a digestive stimulant diuretic to

(37:46):
increase blood flow and also in rheumatism horse ritis. Essential
oil has strong insecticidal activity against larvae of L. Ingenua,
so that means it kills bugs specifically. These larvae and
larvae are not the easiest to kill often, so if
you find something that has strong insecticidal activity against it,

(38:08):
then you go for it. Horse thrash ethanol extracts of
alcoholic extracts had strong fungus static activity, so it stops
fungi against Scleroium roll c roll ci of Fusarium oxysporum
and Fusarium comorum hor resticana was shown to modulate the

(38:37):
adaptive response induced by xsin in human lymphocytes. So xsin
is some sort of of agent in human lymphocytes so
lymph cells and thus could play an important role in
the field of medicine, so that is.

Speaker 1 (38:56):
Interesting as well.

Speaker 2 (39:01):
Charles continues as all Charles eliel Isothia cyanate isolated from
horse rash showed good insecticidal efficacy against the four stored
product pests, maize, weavil. I'm not even gonna there's I
have the Latin here, but I'm not even to attempt it.
So the maize, weavil lesser grain bore tribolium for a

(39:25):
geneum because it wasn't a common name for that, and
book lause with non gaseous residuals on stored products. So
if you are having infestations in your stored product pests,
then this is a possible interesting approach to that. Horse
rash roots in a pilot scale study were found to

(39:46):
make a complete removable phenolic odorance with the detection limit
of point five milligram leaders per leader from the swine slurry.
Another study showed COX one enzigming cancer cell growth inhibitory
monoglactoi soul diasoal glycerized from wasabie and horse thrash rhizomes. Okay,

(40:08):
that's a lot of scientific babbyl. This pilot studies means
it is improven, but there are indications that it has
other things that.

Speaker 1 (40:17):
It can do as well.

Speaker 2 (40:19):
And horse rash, as we've been mentioning, is high end
glucosinolates which have strong antioxidant properties, so very anti antioxidant Greenwald.
Remember that's the PDR for herbal medicine. Sins that's plural.
Herbal medicines say horse rash works anti microbily against gram

(40:43):
positive and gram negative pathogens, and its hyperreemic on skin
and mucous membranes and carcinostatic due to the mustard oils carcinostatic.
Carcinostatic means it stops cancer. Horse rash demonstrated and anti
spasmodic effect in animal experiments. And while we mentioned it earlier,

(41:05):
the science around horsessed peroxidase is actually really useful scientifically,
h says horses rized peroxidase predominantly hrpc SO subtype C
is used as a reagent for organic synthesis and biotransformation,
as well as in coupled enzyme assays, chemiluminescent assays, immunoassays,

(41:33):
and the treatment of waste water. So lots of very
useful effects for that.

Speaker 1 (41:42):
As always, we.

Speaker 2 (41:44):
Want to look at drugrib interactions and see if there
is any of those that might be of potential concern. So,
while horse hash peroxidase is often including studies involving cetochroon
P for fifteen P glycoprotein interactions does not appear to
have a direct in vivo involvement drug rib interactions. Other words,
it's used as part of the assay to determine if
there's interactions, not that it actually has interactions. It's interesting

(42:08):
because the way I look for these things is I'll
put in the herb, sometimes the common name, often the
Latin name, and say end chromosome syachroopy for fifteen interactions
and pea glycoprotein interactions, and see what comes up. There's
lots that came up because it's used in determining other

(42:28):
drug GURB interactions. So that's why I mention it here.
The American Urbal Products Association's Botanical Safety Handbook by Gardner
mcguffin love. This book puts this herb in interaction Class A,
which is their highest rating herbs for which no clinically
relevant interactions are expected. In other words, they don't expect

(42:50):
to have Druggerb interactions. And that makes sense. I mean,
this is a food, not that foods can't have drug
ERB interaction, can't have interactions, but they're probably since they
are used quite often, and you know, any interactions would
be pretty well known. So no interactions. According to appa's
Botanical Safety Handbook, the American Rebel Products Associations web MD

(43:13):
says horse rash might decrease thyroid activity, which we mentioned
was one of it's it's actually one of its its
traditional uses. Taking horse rash along with thyroid hormone might
decrease the effects of thyroid hormone. So that's the only
Drugger interaction I could really come up with for this,
And you know it's there's no evidence showing this, so

(43:37):
that makes it a D level evidence, the lowest level
of evidence for Drugger interaction. But it certainly is worth
taking into account because several different sources mentioned it may
affect the thyroid. So let's get into some concerns about
horse rash. So according to Groenwald, again that's the PDR
for verbal medicines and his team I should always say

(43:59):
at all and his horse rash has some concerns because
of the mucous membrane irritating effect of the mustard oils.
The intake of the drug should not be carried out
in the presence of stomach or intestinal ulcers or in
patience with the history of kidney disease. Commission E says
preparations of horse rash should not be administered to children

(44:20):
under four years of age, though there is no evidence
of adverse effects in this age group. Web MD has
several concerns and precautions with the herb when taken by mouth.
Horse rash root is commonly consumed with foods. It is
possibly safe when used as medicine for up to twelve weeks,

(44:44):
but it contains mustard oil, which can irritate the lining
of the mouth and stomach when consumed in large amounts.
Side effects might include stomach upset, bloody, vomiting, diarrhea, and
fainting when applied to this skin. Horses irish is possibly
safe when preparations containing two percent mustard oil or less

(45:05):
are used, and it can cause skin irritation and allergic reactions.
We always have to be concerned about allergic reactions in pregnancy.
Horse irish is likely unsafe to use horse rash tincture
by mouth regularly or in large amounts when pregnant. This

(45:27):
might lead to miscarriage. Cornate again is still web empty.
Breastfeeding horse rash is likely unsafe to take. Horsesrash is
likely unsafe to take by mouth in large amounts When
breast feeding horsehrash contains must roder, which can pass into

(45:48):
breast milk and cause serious adverse effects children. Horse rash
is likely unsafe when taken by mouth and children under
four years of age, and can cause stomach problems in
young children to hard stomach core, intestino ulcers, inflammatory bowel disease, infections,
or other digestive tract conditions, horse rash can irritate the

(46:12):
digestive track. In general, don't use horse rash if you
have any of these conditions, and in thyroid disorders, horse
rash might make this condition worse. If you have a
thyroid disorder, speak with your health care provider before taking
or shradish holmes. Remember that's the energetics of Western nerves

(46:33):
has some cautions as well. Do not overdose, as horse
rash is hot stimulation quality may irritate the kidneys or
the gastric mucosa. For the same reason, this remedy is
contraindicated in all hot conditions systemic or local, including acute
inflammation during pregnancy and with thyroid deficiency present. Discontinue if

(46:58):
it causes diarrhea or ni sweats. With all of this
into consideration, Gardner and mcguffin, that's the American Herbal Product
Association's Botanical Safety Guide put this herb in the safest
category safety Class one herbs that can be safely consumed
when used appropriately. And I think that's the key. A
lot of what the concerns and cautions were is it

(47:20):
was used inappropriately for the most part. So Gardner mcguffin
safety Class one herbs that could be safely consumed when
used appropriately.

Speaker 1 (47:35):
Okay, take a deep breath. We did it.

Speaker 2 (47:37):
So we started our discussion today by talking about the
role fats and lipids playing Chinese medicine. From there, we
did our deep dive into horseradish, another delicious and helpful
herb for a variety of conditions including cough and bronchitis,
infections of the bladder, inflammation, muscle aches, and digest among others.

(48:02):
And the science is generally positive about its effectiveness for
many of these kids, not all, so a lot of
research to do, but some of them actually not bad
well generally considered to be safe, there are some potential
precautions overall, another interesting and tasty herb. In our next episode,

(48:26):
we will be exploring interesting Chinese quote unquote herb sure
sure sure or a hollowacite or kalein. This mineral is
in the Chinese medical category of herbs that stabilize and
bind and can be used in a wide variety of conditions,
including chronic dirhea, uterine bleeding, and chronic soares.

Speaker 1 (48:48):
And as usual we will.
