Total alkaloid extracts of T. iboga - often called "Indra extract

Ibogaine is also available in a total alkaloid extract of the Tabernanthe iboga plant, which also contains all the other iboga alkaloids. It is darker and deeper in colour to ibogaine and comes as a brittle lump.
Many prefer to use iboga in this form or in the form of the (botanical product) root bark due to the difference in feel of the experience. But the experience is slower and smoother.
Experience  with an extract is less intense - The reason is synergistic effect of the other alkaloids present in Indra extract. The Indra extract contains a reported 15% total alkaloids by weight of which 8% is ibogaine. As the other alkaloids in the Indra product are active, this material is viewed as having a 15% potency.
The exact methods and quality of the original Indra extraction was never documented, so the real composition of the product remains uncertain.
