A witch doctor was originally a type of healer who treated ailments believed to be caused by witchcraft. The term is now more commonly used to refer to healers, particularly in regions which use traditional healing rather than contemporary medicine.

A folk healer is an unlicensed person who practices the art of healing using traditional practices, herbal remedies, and the power of suggestion. The term "folk" was traditionally associated with medical and healing practices that weren't explicitly approved by the dominant religious institution. If people didn't seek healing from an approved priest or religious figure, they would seek the help of the local folk healer. Folk healers, despite their technical illegitimacy, were often viewed as being more involved with the healing process and made their patients more comfortable than other practitioners. With modern medicine being preferred, some look towards folk healers to get consoled from the sacred use of traditional medicine.
