Prickly Heat is the popular name in India and other tropical countries for a form of skin disease sometimes known as Lichen tropicus (see LICHEN). It more frequently attacks strangers from temperate climates than the natives, although the latter are not altogether exempt from it. It consists in a copious eruption of small red papules. The sensations of itching and stinging which attend it are intense, and give rise to an almost irresistible propensity to scratching, which of course only aggravates the irritation. Little or nothing can be done in the way of treatment, except keeping as cool as possible.
