A bomoh is a Malay shaman and traditional medicine practitioner. The term is used mainly in Malaysia and parts of Sumatra, whereas most Indonesians use the word dukun. It is often mistranslated into English as medicine man or witch doctor. In colloquial usage, the term bomoh is often interchangeable with another type of shaman, the pawang, but they generally serve different functions. The bomoh is primarily a healer, herbalist, geomancer, and sorceror. The pawang on the other hand usually specialises in rituals involving weather, nature, animals, and a good harvest. Their roles do overlap however, and both act as an intermediary for the spirits and gods.
The word bomoh (at times spelled bomo or bomor) has been in common usage since at least classical times. It is a cognate of the Thai term maw or mohr. This word can mean either doctor or a sorceror, as in terms like mawpii (spirit doctor) and mawduu (fortune-teller). Prior to the later introduction of the English-derived "doktor" or the Arabic word "tabib", the bomoh served as healers and physicians in Malay society. Thai shamans or bomoh Siam are traditionally held in high regard in Malaysia. Malay texts such as the Hikayat Aceh (1600-1625) record the word bomoh simply as mo or moh.
Shamanism in Southeast Asia can be traced to the region's prehistoric tribal people. The bomoh's original role was that of a healer and their expertise was first and foremost an in-depth knowledge of medicinal herbs and tajul muluk or Malay geomancy. This was supplemented by Sanskrit mantera (mantra) owing to the ancient Hindu-Buddhist influence in the region. Before European colonisation, bomoh - along with Buddhist monks and Hindu holymen - were often exempt from paying taxes, due to the fact that many of them had few material belongings.
The bomoh's craft remained largely unchanged even after Islam became dominant until the Islamic revival in the 1970s and 80s. Bomoh were then seen as deviant from the Muslim faith because of their invocation of spirits and the potentially harmful black magic they were accused of practicing. This period saw a drastic decline in traditional herbalism and many fraudulent practitioners filled the void. As a result, bomoh are today looked at with suspicion even though they are still commonly consulted for personal reasons. Many bomoh today have tried to adapt their practice in the context of modern Islam, such as reciting verses of the Quran or invoking the names of Allah, but this is viewed as shallow by conservative shamans.
