Overview
Camphor is one of the herbs traditionally used in Ayurveda for conjunctivitis. Karpura (Camphor) is the first substance described in the Karpuradi Varga, the second chapter of Bhavaprakash Nighantu. Four types are described: (1) Bhimseni — the best, from Dryobalanops camphora trees in Borneo/Sumatra, naturally deposited in wood crevices; (2) Chini — from Cinnamomum camphora, obtained by distillation; (3) Pachi/Bapani — from Blumea species; (4) Synthetic — chemically prepared. Bhimseni is preferred for medicinal use. Camphor is cold in potency, aromatic, and used extensively in heart diseases, burning sensations, fevers, and eye conditions. It is a cardiac stimulant in small doses. Excessive use can reduce sexual potency. Applied externally for skin conditions and pain relief. Book reference: Karpuradi Varga, shloka 1-3.
