CAMOMILE, or more properly CHAMOMILE, the flowers of the Anthemis nobilis. The flowers have a white ray with a central yellow disk, and have an aromatic bitter taste and a powerful odour. The infusion of the flowers is when cold a useful stimulant, bitter or tonic; the infusion taken warm, however, acts as an emetic. The virtues reside in a volatile oil, and in a bitter principle, which may be separated from one another.
