Title: Plants and Human Cosmologies
1Plants and Human Cosmologies
2Cosmologies
- Cosmologies are branches of philosophy which deal
with the origins and structures of the universe -
religions that explain how the universe formed
and our place within it are one kind (a very
powerful kind) of cosmology
3The sacred Maori Waka Huia
4From William Blake
- "If the doors of perception were cleansed every
thing would appear to man as it is, infinite. For
man has closed himself up, till he sees all
things through narrow chinks of his cavern."
The Marriage of Heaven and Hell - 1793
5Entering the Another World
- In the western tradition, plants and plant
products are used symbolically. - Ritual intoxication is the point of many
religions that use plants to enter another world.
6Quanah Parker Last Commanche Chief, co-founder
of Native American Church
- The white man goes into his church and talks
about Jesus the Indian goes into his tipi and
talks to Jesus.
7Areas where special plants are used to enter
another world
8Cover of English edition Of Phantastica by Louis
Lewin
9Categories of Psychoactive Plants - from Lewin
Phantastica
- Euphorica - sedatives of mental activity - this
group included opium and its derivatives morphine
and heroin, as well as cocaine - Phantastica - drugs that cause evident cerebral
excitation in the form of hallucinations,
illusions, and visions - may be accompanied by
unconsciousness or other symptons of altered
cerebral activity - this group included plants
like Datura sp., belladonna, peyote, ayahuasca
from Banasteriopsis sp., ebena from Virola sp.,
fly agaric, Psilocybe and related mushrooms
10Categories of Psychoactive Plants - from Lewin
Phantastica
- 3. Inebriantia - substances produced primarily
by chemical synthesis or some other manipulation
of raw materials - such as alcohol, chloroform,
ether, benzene - these produce a primary phase of
cerebral excitation, followed by a state of
depression - 4. Hypnotica - substances that induce sleep,
such as kava - 5. Excitantia - stimulants that result in
apparent excitation of the brain without altering
consciousness - coffee, cola nuts, betel nuts,
tobacco
11Hallucinogens
- Hallucinogens are defined as a nonaddictive
substance that consistently produces changes in
perception, thought, and mood, occurring alone or
in concert, without causing serious disabilities
like major disturbances to the autonomic nervous
system. - High doses may elicit disorientation, memory
disturbances, hyperexcitation, stupor, or
narcosis, but these reactions are not
characteristic.
12Hallucinogens
- Strictly speaking hallucinogens should be limited
to those chemicals that mimic serotonin the
indolalkylamines like psilocybin, and
phenethylamines such as mescaline. - But sometimes other substances that cause changes
in mood and perception along with causing
disability are included as hallucinogens. Such
substances include tropane derivatives like
scopolamine, and dibenzpyran derivatives like
THC, tetrahydracannabinol.
13Narcotic
- Strictly speaking narcotic refers to morphine and
related substances that are addictive and
sedatives. But narcotic sometimes is used for
any drug that alters mental state.
14Methodological Considerations
- 1. When studying the plants it is critical to
study them in a controlled clinical setting.
There is a considerable placebo effect with
hallucinogenic and psychoactive plants. - 2. But it is also essential that we test the
plants in the way indigenous people use them. If
they eat the plant, the plant must be eaten.
Indigenous people use psychoactive plants in many
different ways.
15Curandero and Tobacco CeremonySouth America
16Psychoactive plants as a communal experience
- Many psychoactive plants have very subtle effects
and appear to facilitate social interactions
among people - plants included in this group
include plants that yield recreational beverages
such as beer, wine, herba mate, coffee,
chocolate, and tea
17Piper methysticum source of Kava
18Kava Chemical Activity
- The active chemicals in kava are lactones
- The two most important ones are kavain and
dihydrokavain - As Polynesians moved east, they tended to select
plants rich in kavain and poor in dihydrokavain
19Samoan women prepare Kava for the Kava ceremony
20Different varieties of Kava
- There are 9 major groups of kava plant clones -
each differs in chemical activity - A Samoan clone called fellowship and
brotherhood makes one feel very friendly - Another called the white pigeon imparts a sense
of heightened perception, as though one were
flying over the rain forest like a pigeon
21More rapid entry to another world
- Many plants have been used around the world to
enter another realm - as hallucinogens which
permit one to travel to the spirit world - They have been discovered in many parts of the
world and interestingly all have somewhat similar
chemical structure - They all have features similar to serotonin - a
major chemical messenger in the brain
22Chemical structure of serotonin and psychoactive
chemicals
23Virola theiodora source of Ebena
24Justicia pectoralis also used in Ebena
25Ebena The Semen of the Sun
- Ebena is usually prepared from the fresh inner
bark of the tree Virola theiodora (F.
Myristicaceae the nutmegs). It is combined
with ash of the tree Elizabetha princeps (F.
Caesalpiniaceae subfamily of legume trees) and
dried powdered leaves of the herb Justicia
pectoralis (F. Acanthaceae Acanthus family)
26Ebena Chemicals
- The sap of Virola contains the active
ingredients. The sap contains several
psychoactive compounds, primarily tryptamines,
particularly N,N-dimethyltryptamine (DMT),
N-monomethyltrptamine (MMT), and
5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT)
these are all related to serotonin
(5-hydroxytryptamine). The sap also contains
several beta-carbolines, compounds that enhance
the effects of orally ingested tryptamines and
that are psychoactive in their own right.

29Vine of the soul - Banisteriopsis caapi
Source of Ayahuasca
30Ayahuasca or Yaje
- Two species of the vine Banisteriopsis are used,
depending on the area - either B. caapi or B.
inebrians - both produce powerful psychoactive
substances that are beta-carboline alkaloids -
harmine and harmaline - Ayahuasca bark is collected and boiled in a pot,
a bitter tea is produced which is then drunk - Sometimes ayahuasca is used with leaves of
another plant Psychotria viridis to enhance its
effects - it contains N,N-dimethyltryptamine
which is also a powerful hallucinogen
31Psychotria viridis

showing visions received from Ayahuasca
33Advantages of Ayahuasca
- In the words of Padrino Alex Polari de Alverga of
the Santo Daime Community in Brazil, Daime
(ayahuasca) is basically a shortcut, its as if
we had been traveling down the same highway as
the rest of humanity, but then, in order to
arrive at our destination more quickly we took a
side road. When taking such a shortcut, however,
we must be very careful and clear-minded. It is a
shortcut that leads us to truth, but only if we
follow in the footsteps of the Masters who have
preceded us.

- Given to boys in adolescent rites lasting 18-20
days - after which they were considered to be
adults - From it comes stramonium a drug used in the
treatment of asthma - hallocinogenic agents are
tropane alkaloids hyoscamine and hyoscine
38Marijuana Cannabis sativa
39Ancient Use of Cannabis
- 2000 BCE Writings of Shen Nung mention Cannabis
as an important plant for the treatment of
various illnesses including beri-beri, malaria,
and forgetfulness. He also described the plant
as freeing the psyche If taken over a long
term, it makes one communicate with spirits and
lighten ones body.
40Ancient Use of Cannabis
- Writers in China warned that Cannabis was a
liberator of sin. 2000 BCE - By 1500 BCE the plant known as ma was reported
as useful for shamanistic purposes - 2nd Century AD Chinese physicians mixed it with
wine and used it as an anaesthetic during surgery
41Ancient Use of Cannabis
- 500 300 BCE - ancient Scythians in the Near
East used Cannabis as a psychotropic drug - Herodotus reported that Scythians delighted in
vapor baths scented by Cannabis seeds placed on
heated stones - 4th Century BCE - discovered with skeleton in
tomb in Jerusalem
42Al-Hasan ibn al-Sabbah
- By 1090 had established fortress on trade routes
to China and India ruled army of thieves whom
he supplied with hashish and women in return for
their loyalty
43Introduction to Europe
- Europeans were introduced to Cannabis as a
psychoactive plant by Napoleons soldiers after
the conquest of Egypt in 1800. They began by
consuming resin of Cannabis flowers and leaves
(hashish). At first the resin was used to treat
mentally ill, but soon it was used recreationally
too. By 1844 so many fashionable Parisians were
enjoying their visions from use of hashish that
they formed a club, Le Club des Haschischins, and
held monthly meetings at the Hotel Pimodan on the
Ile Saint-Louis.
