Between Remedy and Risk: Changing Medical Understandings of Betel Chewing in Colonial South Asia, 1860–1908

Betel chewing was an established dietary, social and medicinal practice in colonial South Asia, described in nineteenth-century medical writing in therapeutic terms – as a stimulant, digestive aid and carminative. Yet the same body of writing came to carry a competing interpretation. In 1860, James Emerson Tennent’s Ceylon recorded, in a footnote, Dr Elliot’s observation of several cases of cancer of the cheek among chewers, which Elliot termed “betel chewer’s cancer” – a passage the International Agency for Research on Cancer identifies as the earliest reference of its kind. This paper traces how that observation developed, between 1860 and 1908, into a body of clinical investigation, examining the writings of William Niblock, A. P. Bala Ram, W. C. Bentall and A. Fells. Rather than presenting this history as a transition from acceptance to rejection, it argues that what changed was the kind of question physicians asked of betel: individual observation gave way to hospital records, numerical tables and increasingly explicit causal language, without these texts isolating a single responsible constituent of the quid or mechanism by which chewing produced oral disease. Older therapeutic meanings persisted alongside emerging pathological concerns. The paper’s central claim is that this period made betel chewing into a medical problem requiring investigation, and that its significance lies in the gap between recognition and explanation, rather than in a settled discovery of cause.
