Via SAGE Open Medicine, Brazilian scientist Eduardo E. Schenberg lays out psychedelic shamanic drug’s possible anti-tumor properties in great detail and calls for further investigation into its use as an alternative cancer treatment:
Used for centuries in the Amazon basin by healers and shamans for many different purposes, including the healing and curing of illnesses, ayahuasca is a plant decoction that may be useful in the treatment of some types of cancer. The decoction is most commonly made of two plants in two possible combinations: Banisteriopsis caapi with Psychotria viridis or B. caapi with Diplopterys cabrerana.
There are at least nine reports of cancer patients who consumed ayahuasca during their treatment. Four were reported in a peer-reviewed article, one in an institutional magazine, one in Internet sources, two in a scientific conference (later mentioned in a peer-reviewed article), and one in a book. The origins of these cancers were the prostate, colon, ovaries, breast, uterus, stomach, and brain.
