RSB is long known for ethnobotanicals, I suggest you search engine ethnobotany to learn what it means. In the simplest terms ethnobotany is the science of sacred and medicinal plants of indigenous people. Plants such as peyote cactus, tabernantha iboga, San Pedro cactus, Ayahuasca, ephedra plants. morning glory seeds. Even marijuana is an ethnobotanical, however, I don’t deal in that due to its legal status.
