Siberian shamans eat Amanita muscaria in order to enter a clairvoyant trance state and mobilize their shamanic powers of healing. Amanita muscaria are also ingested when they wish to communicate with the souls of their ancestors or to contact spirits. One to three Amanita mushrooms appear to be the usual traditional dose with initial Amanita effects being felt in about twenty minutes. It was the practice of Siberian and other tribes to recycle the urine of someone who had already eaten Amanita muscaria, and thus, because a substantial amount of active substances in it remained unchanged, it could be used for later or given to someone who could not afford to buy Amanita muscaria.
