Iboga
Normally, the plant grows to a height of about 2m. It may eventually grow into a small tree up to 10 m tall. It has small green leaves. Its flowers are white and pink, while the fruit can be either an elongated oval shape, or a round spherical shape. Fruits are orange in color. Its yellow-colored roots contain a number of indole alkaloids, most notably ibogaine, which is found in the highest concentration in the root-bark. The root material, bitter in taste, causes anesthetic sensation in the mouth as well as systemic numbness to the skin.
