Before 1900
Living traditions precede the written archive
Iboga’s use in Gabon and nearby parts of Central Africa is associated with Bwiti religious and healing traditions. Oral transmission, ritual practice, and local knowledge precede European scientific naming; outside records are not the origin of that history.
Descriptions of an unchanged “ancient practice” should be treated cautiously. Traditions change, communities differ, and many claims about exact antiquity or sequence are difficult to verify from primary sources. Cultural discussion needs more than a laboratory timeline, including the context explored in Bwiti and iboga traditions.
