Urticaria (chapaki), also known as sheet pitt in Ayurveda, is an allergic skin disorder that is characterised by the appearance of raised rashes
, redness and itching. It can happen anywhere on the skin
including the scalp, lips, palms, soles and even genitals. Ayurveda believes that urticaria occurs in response to certain substances which are produced in the body as a result of metabolic disturbances. It may occur due to indigestion, overeating or because of eating food unsuitable for the body.
