CHAMOMILE, or CAMOMILE See also:FLOWERS , the flares anthemidis of the See also:British See also:Pharmacopoeia, the See also:flower-heads of Anthemis nobilis (Nat. Ord. See also:Compositae), a See also:herb indigenous to See also:England and western See also:Europe. It is cultivated for medicinal purposes in See also:Surrey, at several places in See also:Saxony, and in See also:France and See also:Belgium,—that grown in England being much more valuable than any of the See also:foreign chamomiles brought into the See also:market. In the See also:wild plant the florets of the See also:ray are ligulate and See also:white, and contain pistils only, those of the disk being tubular and yellow; but under cultivation the whole of the florets tend to become ligulate and white, in which See also:state the flower-heads are said to be See also:double. The flower-heads have a warm aromatic odour, which is characteristic of the entire plant, and a very See also:bitter See also:taste. In addition to a bitter extractive principle, they yield about 2 % of a volatile liquid, which on its first extraction is of a See also:pale See also:blue See also:colour, but becomes a yellowish See also:brown on exposure to See also:light. It has the characteristic odour of the flowers, and consists of a mixture of butyl and amyl angelates and valerates. Angelate of See also:potassium has been obtained by treatment of the oil with See also:caustic potash, and angelic See also:acid may be isolated from this by treatment with dilute sulphuric acid. Chamomile is used in See also:medicine in the See also:form of its volatile oil, of which the dose is 1-3 minims. There is an See also:official See also:extract which is never used. Like all volatile See also:oils the See also:drug is a stomachic and carminative.

In large doses the infusion is a See also:

simple emetic. Wild chamomile is Matricaria Chamomilla, a See also:weed See also:common in See also:waste and cultivated ground especially in the See also:southern counties of England. It has somewhat the See also:appearance of true chamomile, but a fainter See also:scent.
