It can be inhaled for sore throats, used in baths to soothe anal or genital inflammation, and used internally for stomach and intestinal spasms and inflammatory diseases. However, clinical proof supporting any of these uses of chamomile is limited.Traditional and ethnobotanical uses

Chamomile has been utilized as a skin wash to clean wounds and ulcers, and to increase the sloughing of necrotic tissue and promote granulation and proper healing.
