Ethnopharmacologic Search for Psychoactive Drugs (Vol. 1 & 2): 50 Years of Research
This current price is amazing. My parents got it for me for Christmas for the full price, when I got it, and it is one of my most priceless and prized possessions. It’s so fascinating, all they mention from 50 years ago, and all they mention as of recent — both are equally utilitarian, but in different ways. I almost prefer volume 1 (from 50 years ago). And this is the combo pack of volume 1 and 2. Massive information, tons of plants most people here haven’t ever even heard of, yet. So cool that research was so extensively done on psychedelic plants, over 50 years ago, with the same degree of scientific interest as books such as PIHKaL and TIHKaL, by Alexander Shulgin.
One more VERY good and comprehensive book on the topic is this one. Which, while not directly based on the topic, has a lot of good and interesting information on both traditional psychedelic usage and the biological mechanisms behind a psychedelic state. https://www.amazon.ca/Ethnopharmacologic-Search-Psychoactive-Drugs-Vol/dp/0907791689/ref=asc_df_0907791689/?tag=googlemobshop-20&linkCode=df0&hvadid=296033590701&hvpos=&hvnetw=g&hvrand=1268817328341778657&hvpone=&hvptwo...
