Botanical product root bark itself usually contains between 1% and 4% alkaloid content - sometimes less, sometimes more - of which 50% is ibogaine.
The rootbark of the Tabernanthe iboga plant is usually referred to as 'iboga' or 'eboka' and it has two principal uses within the Central African religious group. Firstly, small doses are used as a stimulant, principally when hunting and as an aid to ritual work. And, secondly, a much larger dose features as a central element of the 'Bwiti initiation ritual' - a powerful 'rebirth' ceremony that group members typically undergo before the commencement of their teenage years, and is a requirement for group membership. Both sexes are initiated and the ceremony typically lasts three days.
Iboga is eaten on the first night of the initiation ceremony and may be further consumed on subsequent nights should it be deemed necessary. The consumption of iboga is supervised by the 'nganga', a senior priest of the religion whose knowledge of iboga's effects on the body and mind is such that he or she is aware of when the initiate has had sufficient. The overall objective of the ritual is to allow the initiate to enter deeply into the subconscious mind with the intent of emerging 'reborn'. In the depths of this inner realm, he or she is expected to actually 'meet' the original Bwiti, the founders of the religion, in the form of primordial male and female figures. But this can only be achieved once mighty terrors that lurk before them have been overcome.
This 'inner journey' is analogous to that undertaken by many 'hero' figures in classical mythology. And, in more Western terminology, it might be said that the usage of large doses of iboga here is intended to remove the effects of accumulated trauma or conditioning on the system. And further facilitate access to archetypal figures located within the Jungian concept of the 'collective unconscious'.
Once initiation is completed, the person becomes a full member of the Bwiti religion. And the act of having confronted the fears of those who went before means the individual may now be regarded as an adult.
