Chamomile or camomile (/ˈkæməˌmaɪl, -ˌmiːl/ KAM-ə-myl or KAM-ə-meel) is the common name for several daisy-like plants of the family Asteraceae that are commonly used to make herb infusions to serve various medicinal purposes. Popular uses of chamomile preparations include treating hay fever, inflammation, muscle spasms, menstrual disorders, insomnia, ulcers, gastrointestinal disorders, and haemorrhoids. Camomile tea is also used to treat skin conditions such as eczema, chickenpox and psoriasis.
The word "chamomile" derives, via French and Latin, from Greek χαμαίμηλον (khamaimēlon), i.e. "earth apple", from χαμαί (khamai) "on the ground" and μῆλον (mēlon) "apple". The more common British spelling "camomile," is the older one in English, while the spelling "chamomile" corresponds to the Latin and Greek source. The spelling camomile more accurately corresponds to the more immediate derivation from French.
