For harmony between the living and the dead, vital for a trouble-free life, traditional healers believe that the ancestors must be shown respect through ritual and animal sacrifice. They perform summoning rituals by burning plants like "imphepho" ("Helichrysum petiolare"), dancing, chanting, channelling or playing drums. Traditional healers will often give their patients "muti"—medications made from plant, animal and minerals—imbued with spiritual significance. These muti often have powerful symbolism; for example, lion fat might be prepared for children to promote courage. There are medicines for everything from physical and mental illness, social disharmony and spiritual difficulties to potions for protection, love and luck.
