umuthi

Muti in South African English comes from Nguni umuthi, especially Zulu and Xhosa, where the older core meaning is tree, wood, or plant. From that concrete sense came medicine, because medicine was made from plant matter and bark long before pharmacies sold it in bottles. Nineteenth-century lexicographers recorded both senses. The metaphor was not metaphorical at all. It was practical botany.

The transformation from plant to cure is ancient and ordinary. What changed in the colonial period was the frame around the word. English speakers in southern Africa borrowed muti for African traditional medicine, often with fascination and distrust mixed together. That mixture tells you more about colonists than healers.

By the twentieth century the word had split into registers. In everyday South African English, muti could mean medicine generally, but also specifically herbal or ritual medicine associated with indigenous healing. Sensational press usage then distorted the term through the phrase muti murder, one of the ugliest examples of a living medical vocabulary being dragged into lurid shorthand. Language can preserve contempt with alarming efficiency.

Today muti still names medicine in wide use, especially in South Africa, and it remains tied to traditional healing systems with deep local legitimacy. The word is also a reminder that English loans often arrive with colonial grime on them. Strip that away and the older sense is still visible. Medicine was wood before it was myth.
