Dr Mark Plotkin on Ethnobotany, Real vs Fake Shamans, Hallucinogens, and More | The Tim Ferriss Show

Plotkin traces his career back to mentor Richard Evans Schultes, the father of ethnobotany, and explains how plant and fungal medicines function as 'vegetal scalpels' that can heal or harm. He recounts decades of fieldwork across hundreds of Amazonian cultures, including firsthand experiences with ayahuasca, yopo, and hallucinogenic frogs, while cautioning that these compounds carry real risks and require genuine shamans rather than internet-sourced operators. He details the Amazon Conservation Team's work teaching tribes to map their own lands, document their medicinal knowledge in their own languages, and build sustainable livelihoods like honey production. The conversation connects the COVID-19 pandemic to the abuse of wildlife and argues that conservation, indigenous knowledge, and Western science must be combined to prevent future pandemics and preserve irreplaceable healing traditions.

• A single black-and-white slide in a Schultes night-school lecture, showing three Yukuna Indians doing a tribal dance with the punchline 'the one on the left has a Harvard degree,' hooked Plotkin on ethnobotany for life.

• A shaman cured Plotkin's persistent foot injury on the spot using a scraped fern from a palm tree, after aspirin, a cortisone shot, massage, and acupuncture had all failed.
  00:16:48
• Yopo, a hallucinogenic snuff from the Venezuela-Brazil border, is Plotkin's personal favorite hallucinogen; it hurts intensely for minutes, produces a 20-minute visual spiritual trip, then leaves the user feeling wonderful.
  00:23:34
• A Suriname shaman revealed a local hunting-magic frog (containing bufotenin) that Plotkin had not learned in over 30 years of work, saying 'you've been working here over 30 years and you never asked me.'
  00:25:08
• Plotkin says he has taken ayahuasca about 87 times, almost always as part of bonding and ceremony with the original ayahuasca tribes rather than for personal problem-solving.
  00:29:49
• Plotkin was bitten on the leg by a vampire bat while camping on the Suriname-Brazil border; the wound bled heavily because vampire bat saliva contains an anticoagulant now studied under the trade name 'draculin.'
  00:41:14
• Rather than make maps for the Trio tribe, ACT taught them to make their own maps, leading them to discover 13 stands of Brazil nut trees outside the Amazon Basin and document their own medicinal knowledge.
  00:47:26
• A shaman healed Plotkin's racquetball forearm injury over a month with topical plants, a drink, and chanting to remove 'a bad relationship buried in that muscle,' then applied a 'shamanic patch' so it would never return.

• Schultes went into southern Mexico in the 1930s and brought back magic mushrooms, then went into the northwest Amazon in the 1940s and brought out ayahuasca.
  00:07:20
• Schultes went to the Amazon in 1941 and essentially 'went native' for about 14 years.
  00:11:03
• Linnaeus described the first electric eel and Volta built the first battery inspired partly by studying electric eels; in 2019 two new species were found, one producing 20% more electricity than previously known.
  00:20:59
• The Yanomami make two kinds of yopo: one from virola tree sap (an Amazonian nutmeg) that is intensely visual, and one from crushed savanna-tree seeds that is primarily auditory.
  00:30:20
• In the Northwest Amazon, anyone who claims to be a shaman is not a real one; a true shaman will only say 'some say that I am,' and one 90-plus-year-old taita said he was 'still learning.'
  00:33:26
• Vampire bat anticoagulant being studied in labs carries the trade name 'draculin.'
  00:42:17
• Poisonous snakes led to the development of ACE inhibitors, now a billion-dollar drug industry, illustrating why 'creepy crawlies' deserve conservation, not just cute animals.
  00:43:20
• After three different tribes (Trio, Wayana, Maroons) independently showed Plotkin different male aphrodisiac plants, a Harvard medical contact insisted aphrodisiacs were physiologically impossible; later a blood-pressure-drug dosing accident in a nursing home accidentally revealed the same effect.
  00:55:14
• The Aquario hunter-gatherers have 34 words for honey; ACT helped them build a sustainable honey business in which no trees are cut down.
  01:00:58
• Plotkin argues COVID-19 originated from a bat crammed in a cage in Wuhan, and that the wildlife trade is the largest illegal market after narcotics and munitions.
