In this episode of Ayahuasca Podcast host Sam Believ (founder of www.lawayra.com) has a conversation with Dr. Waifung Tsang. Waifung is a clinical psychologist, researcher and co-founder of Onaya Sciences, bridging Western psychology with indigenous Amazonian plant medicine, Chinese medicine and sound-based therapies. He also advises Heroic Hearts UK and is a TEDx speaker exploring the intersection of trauma, psychedelics and traditional wisdom.

We touch upon topics of:

  • (00:55–04:38) Waifung’s journey from music and disillusionment in clinical psychology to ayahuasca research in Peru and co-founding Onaya Sciences
  • (06:34–11:38) Why ayahuasca is almost invisible in China: censorship, historical suppression of spirituality and underground ceremonies
  • (11:38–13:58) Dragons, the Monkey King and how Chinese mythology, Taoism and Buddhism resonate with psychedelic experiences
  • (13:58–19:22) Tai Chi, qigong and Chinese medicine as tools for working with plant diets, chi and ceremony
  • (19:22–24:19) Parallels between Chinese medicine and Latin American folk wisdom: hot/cold foods, grandmothers’ knowledge and collectivist spirituality
  • (24:19–29:20) Emerging ayahuasca circles in China, Hong Kong and Taiwan — encrypted forums, harsh penalties and why many seekers are business people
  • (29:23–34:57) From NHS burnout to the jungle: what Waifung learned from indigenous doctors who treat “whoever comes” with plants, ritual and Icaros
  • (35:13–39:19) Onaya’s research with Heroic Hearts: veterans, PTSD, traumatic brain injury and early multi-modal findings
  • (39:19–43:18) Multi-site collaborations with retreat centers, indigenous advisory boards and studying Icaros, dreams and plant spirits
  • (45:04–47:28) Epigenetics 101: how ayahuasca may influence gene expression and “straighten ancestral lines” — and why much larger samples are needed
  • (52:50–59:29) Medicine music, energy in ceremony, “bad DJs” vs surgical Icaros, and a new EEG study recording shamans’ songs and brain activity
  • (01:01:18–01:04:18) How ayahuasca heals on bio-psycho-social-spiritual levels and why community and integration matter as much as the visions
