A Witch Doctor originally referred to a type of healer who treated ailments believed to be caused by witchcraft. It is currently used to refer to healers in some third world regions who use traditional healing rather than contemporary medicine. In the first world, it is sometimes used derogatorily to refer to chiropractors, homeopaths and faith healers.
In its original meaning, a Witch Doctor was emphatically not a witch himself or herself but rather the person who had remedies to protect others against witchcraft. Witchcraft-induced conditions were his or her area of expertise.
So saying, Witch Doctors are not bad as some people tend to believe because of the description or name as they protect victims of witchcraft which, as far as we know, are followers of the devil and this Witch Doctors sometimes can return the spell or ailment to the witch who tried to do harm to the victim, depending how strong they are. There are some bad Witch Doctors and then also, some bad real Doctors but the majority of the people that we call Witch Doctors or ARBULARYO in the native tongue are real people and not bad, though there are some fakes.
