Preparation.—"Take of chamomile flowers 1 pound (av.), oil of chamomile 15 minims, distilled water 1 gallon. Boil the chamomile with the water until the volume is reduced to one-half; then strain, press, and filter. Evaporate the liquor by a water-bath until the extract is of a suitable consistence for forming pills, adding the oil of chamomile at the end of the process (Br. Pharm.). This is an aqueous extract of deep-brown color, representing the odor and bitter taste of the flowers. An alcoholic extract may be prepared as follows:
