I found this really intresting abstract for a study done with Ayahuasca:
Abstract Eight channels of EEG from 12 volunteers participating in a workshop in Brazil were recordedunder field conditions before and after a shamanistic ritual in which the psychoactive tea, ayahuasca, was consumed. Following three doses of the tea, the subjects showed strong and statistically significant increases of both EEG alpha (8-13Hz) and theta (4-8Hz) mean amplitudes compared to baseline while beta (13-20Hz) amplitudes were unchanged. The strongest increases of alpha activity were observed in the occipital lobes while alpha was unchanged in the frontal lobes. Theta amplitudes, on the other hand, were significantly increased in both occipital and frontal areas. Our data do not support previous findings of cortical activation with decreased alpha and increased beta activity caused by psychedelics (e.g. LSD, mescaline, psilocybin). They rather point to a similarity between the altered states produced by ayahuasca and marihuana which also stimulates the brain to produce more alpha waves. We suggest that these findings of increased EEG alpha and theta activity after drinking ayahuasca reflect an altered state of consciousness. In this state thesubjects reported increased awareness of their subconscious processes. This is an altered state comparable to, however more profound than, the meditative state. Our results suggest that ingesting Ayahuasca may provide individuals with increased access to subconscious processes and feelings while in a wakeful, relaxed state. Thus, Ayahuasca has the potential to become a potent tool in the process of psychotherapy.
Very interesting stuff as the article is saying that the effects of Ayahuasca seem to increase alpha and theta waves in the brain which represent meditative states or relation to stages of drowsiness and stage 2 of sleep.

Over the last few days I have been reading the book “Food of the Gods” and it really is a great read. I am not one to be really interested in Terence McKenna in the past as he seems to be more of a Timothy Leary of his time, with individuals flocking to his teaches and seeming to be more of a religious teacher than anything, but after reading his book (or the most of it) I have become to really see why people would want to come hear him teach. In his book Food of the Gods, McKenna provides us a very detailed history of how drugs were used and why they are used like they are today.
One of the many things that I found interesting is how McKenna theorizes alcohol use came about. He talks about how psychoactive mushrooms were put into honey in order to be preserved for long periods of transportation as honey was used a preservative, even for bodies. It was most likely found that honey was fermented over time and increased the affects of the mushrooms and produced its own mind altering experience. Mead was made and produced at this point and after clutres came into power that didnt allow for mind altering mushrooms to be used (at least for the average person) then mead started to become more popular.
I found it interesting as well that McKenna points out that throughout history humans have always used substances that alter consciousness, and most importantly when they are told that they cant use those substances, they revolt.
Anyways a great read and highly recommended. I can not even come close to providing a justly informative summery of his book as it is full of important information in understanding why the drug situation is what it is today.
So I was doing some research in a handy dandy book I have ” The Encyclopedia of Psychoactive Plants and found another plant with a higher concentration of DMT. Though Acacia confusa does rate a high percentage of DMT, Diplopterys cabrerana contains 1.75% DMT in its fresh dried leaves. I dont know where that article received is information but clearly it is not the highest contain source known to mankind. It is though true that Acacia confusa recently was studied to find out what kind of active compounds were located in the plant, and DMT was one of those.
I was reading around at some twitters and found a great blog on dreaming: Notes From a Dreamer. Its one of the few informative blogs that I have been able to find that are up-to-date. I recommend everyone checks it out. here
I have started to read the book Food of the Gods by Terence McKenna and it really has been an enjoyable and enlightening read. I have only gotten through about 1/3 of the book, but he does a good job in explaining the evolution of mankind and how it may have come about with the help of entheogens. I have read a lot of other works on the subject of religion and the use of psychoactive substances in order to understand the evolution or religion, but I have always wondered where they got their source of ideas. It seems that McKenna may have been that source.
Terence McKenna is a well educated and well traveled man, and you can see this in his writings. He could be described as an anthropologist even though he only had a Bachelor of Science degree in Ecology and Conservation. The one great thing is that McKenna is that in his writings he doesnt come off as an aggressive person. He shows a way that’s possible and kind of lets you decide. He intrigues you with interesting stories and situations and lets you find your way. I have heard a few of hes recorded speeches, but never really liked the guy because of how people seemed to follow him (cult style) but I do enjoy his writing and agree that this is one possible explanation into our relationship of plants.
Yesterday I also found an interesting article about The Buddhist practices of tantra and the psychoactive plants that they used. According to the article, it wasn’t until recently that we were able to translate some of the ancient texts which were vital in understanding the Buddhist practices, and through those translations reliable information has been found that both Cannabis and Datura have been used along with the tantric practices as common practice. Datura also has its ties with the Buddhist and Hindu gods.
Datura is associated with several Hindu and Buddhist deities. Vämana Puräëa, a pre-modern devotional text dedicated to Vishnu (date unknown), tells that datura sprouted from the chest of the god Çiva.18 Its flowers are sometimes used as ceremonial offerings—a practice that continues to this day in Nepal.

After reviewing the article that was written by Benny Shanon in 2008, I would like to say that it was a very informative read. I am currently reading the book “Failed God” by John A. Rush where he talks about Christianity, Judaism, and Isam to be started with the use of entheogens. Interesting enough Shanon’s work with this article pretty much sums up all of Rush’s work in a few pages. Shanon also goes into what plants may be the tree of knowledge and focuses on the “newly” researched Acacia Tree as being the source of the large amounts of DMT. Though recently we have been able to determine how much DMT is located in the Acacia Confusa, it still has had the focus as a high yielding DMT source and involved in religious practices for thousands of years.
Over all, anyone that is interested in learning some good hypotheses on the use of hallucinogens in ancient religious practices, you should read Shanon’s article.

Recently new research has shown a new plant on the block containing the highest amounts of DMT to be found yet. Acacia Confusa a plant that grows in the United States including some Pacific areas contains yelds up to 1.15% of N,N-dimethyltryptamine. Dont eat the seeds though as they can cause death.

After searching the internet for a few hours trying to find some other information on some specific plants, I managed to find a good read by accident that was written by Benny Shannon about his hypothesis of what types of plants may have been involved in the starting of religions. I have yet to had the chance to read through it all, but so far its a good read. Shannon has written other great books on the subject of entheogens and all have been great reads. Here is the link to start your own reading on this paper.
