Chamaemelum nobile (L.) All. Asteraceae. English, Roman or garden chamomile Distribution: Europe, Mediterranean. Culpeper (1650): “... assuage swellings, inflammations of the bowels, dissolve wind, are profitable given in clysters or drink, to such as are troubled with colic or [renal] stone.” The leaves are pleasantly fragrant, hence its use as a lawn plant, but also in aromatherapy. A ‘tea’ made from the flowers is apparently used to lighten hair colour. Chamomile contains sesquiterpene lactones, and these are known to possess allergenic properties. Hypersensitivity reactions have been reported in this and other members of the Compositae (Asteraceae) and cross sensitivity reactions may occur (Medicines Control Agency, 2002). Analgesic, and used for cramps and spasms (Quincy, 1718). Chamomile tea is used to help sleep, but may cause uterine contractions so avoid in pregnancy (US National Institutes of Health advice).
