What happens when a PhD pathologist from Brown University leaves Western medicine to merge a 17-generation family tradition with regenerative stem cell science?
On this episode of The Pod of Inquiry, we sit down with Dr. Yi Song, founder of the Zenerchi Clinic outside Medellín, Colombia. Dr. Song’s family has practiced Traditional Chinese Medicine (TCM) for 17 generations—tracing their lineage all the way back to court physicians during the Qing Dynasty. After training extensively in Western pathology, she returned to her TCM roots and built a cutting-edge clinic treating complex conditions using umbilical cord-derived mesenchymal stem cells. (When Ancient Medicine Meets Stem Cells )
In this episode, we break down:
- East Meets West: Fusing a 17-generation TCM lineage with modern regenerative medicine.
- A Personal Miracle: Reversing her own mother’s near-amputation with stem cell therapy.
- The TCM Framework: Understanding “body constitution,” excess heat, and digestive weakness.
- Stem Cell Safety: Cell sourcing, expansion, and the strict “6th-generation” rule.
- Medical Borders: U.S. vs. Colombia regulations and the real quality-control tradeoffs.
- Clinical Insights: Why diabetic nerves swell 50% larger and how it redefines neuropathy treatment.
If you or someone you love has struggled with fertility, hormones, endometriosis, or unexplained reproductive issues, this conversation offers plenty to think about.
This is a fascinating look at what it takes to hold two entirely different medical traditions in one hand and figure out exactly where they complement each other.

Author Biography
Dr. Yi Song
Dr. Yi Song grew up in Beijing, China. She came from a family of 17 generations practicing Chinese Medicine and Western Medicine. She came to the United States 28 years ago to study Pathology at Brown University. After observing the shortcomings of symptom-focused treatments, Dr. Song returned to her roots to focus on true regenerative healing — addressing disease at its source.
She has had a holistic clinic in Boston since 2004. In 2018, she founded the Zenerchi Retreat in Medellin, Colombia. Her introduction to stem cell therapy in 2020 was marked by her mother’s successful treatment and subsequent independence at age 81.
Dr. Song believes that stem cell therapy aligns with holistic principles and is the author of “Regeneration Effect: Sacred Wisdom for Staying Young” and the series of seven books in “The Six Principles to Natural Longevity”.
Her vision is to combine stem cell therapy, Traditional Chinese Medicine, and anti-aging treatments to help people live a long, high-quality life. She offers advanced stem cell treatments at Zenerchi Retreat in Colombia not available in the US. You can also get consultation about your conditions and concerns in person in Boston or at our network of doctors in the US and online.”
Show Notes from this episode
Dr. Yi Song is the founder Clinic in Colombia and a 17th-generation practitioner in a family lineage of Traditional Chinese Medicine physicians — a lineage that, by family account, traces back through Qing Dynasty court physicians in Beijing. She also holds a PhD in pathology from Brown University. In this conversation, Dr. Song walks through her path from Western pathology research to integrative TCM practice to regenerative stem cell medicine, explains the constitutional-typing framework at the core of Chinese medicine, and details how umbilical cord-derived mesenchymal stem cells are sourced, expanded, and administered at her Colombia clinic for conditions ranging from vascular insufficiency to orthopedic injury. The conversation closes with a crossover discussion between Dr. Song and Dr. Barrett on peripheral neuropathy, nerve compression, and where regenerative medicine may fit into that treatment picture.
Timestamped Show Notes
00:00 Episode open — Dr. Barrett introduces Dr. Yi Song, founder of the Zenerchi Clinic, PhD in pathology from Brown University and 17th-generation Traditional Chinese Medicine practitioner.
01:19 Full welcome and framing of the conversation — TCM lineage meets regenerative stem cell therapy.
01:52 Dr. Song’s background: moved from Beijing to the U.S. in 1997 to study pathology, grew disillusioned with symptom-focused Western medicine, and returned to her family’s TCM roots.
03:27 The case that redirected her career — her mother’s lipodermatosclerosis (chronic venous insufficiency), the ‘inverted champagne bottle’ presentation, and the limits of laser ablation treatment.
05:12 Why untreated venous insufficiency and inflammation can progress to skin ulceration and, eventually, amputation.
06:05 The 17-generation family lineage of TCM physicians — how far back it goes and what’s known about it.
08:42 How the lineage was documented and lost — a family tree record destroyed during China’s Cultural Revolution.
10:17 Putting the timeline in perspective: a lineage reaching back further than the history of the United States.
10:50 Inside the Zenerchi Clinic’s location near Medellín, Colombia — the 7,000-foot elevation and why she calls it ‘the land of eternal spring.’
13:03 Six years in pathology research at Brown University, then the pivot toward an integrative model blending Western and Chinese medicine.
13:31 Why she now believes combining TCM with stem cell therapy outperforms Western-only approaches for a wider range of conditions than she originally expected.
15:35 A personal case study: Dr. Song’s own silent acid reflux diagnosis and her decision to decline a proton pump inhibitor.
17:45 Sponsor break — ValAsta Astaxanthin (code POI5 at valasta.net).
19:13 TCM’s concept of inherited ‘body constitution’ and why she believes it’s an advantage over purely test-driven Western diagnostics.
20:13 The first two of the six core tenets in her forthcoming book: recognizing body constitution and early prevention.
21:43 How functional medicine differs from TCM’s constitutional approach — the reliance on lab-driven optimization versus root-pattern recognition.
24:04 Examples of constitutional types: excess-heat constitution, inherited digestive weakness, phlegm accumulation, and stagnation patterns linked to anxiety and depression.
26:26 Barrett asks about the current balance of Western medicine and TCM inside China today.
27:00 Historical context — Mao-era and Cultural Revolution suppression of traditional philosophy, and a family connection: Dr. Song’s grand-uncle served as Mao’s personal physician.
30:05 Dr. Barrett’s own 1987 trip operating in Beijing and Shanghai, and being corrected by a Chinese anesthesiologist dismissive of acupuncture at the time.
31:08 Why TCM found more early interest among Western patients than in China itself — the ‘rock star bigger overseas’ phenomenon.
