hot infusion is given to aid the operation of emetics. The flowers, boiled in warm water, form a good fomentation to inflamed parts. The usual form of administration is the infusion (half a troyounce to water Oj). Dose, as a stomachic, fij, two or three times a day, cold; as an emetic, hot, ad libitum.

COTULA (Mayweed). Anthemis (or Maruta) cotula, Wild chamomile, or Mayweed (Nat. Ord. Asteraceae), an herbaceous plant, indigenous in Europe, but extensively naturalized in the United States, resembles chamomile very closely, both in botanical characters and in properties, and is used as a substitute for it in domestic practice.

MATRICARIA (German Chamomile). The FLOWERS of Matricaria chamomilla (Nat. Ord. Asteraceae), an annual European plant, possess properties very similar to those of chamomile. They are considerably smaller than common chamomile, and have a larger proportion of disk florets compared with those of the ray. They are not much employed in this country.

EUPATORIUM-THOROUGH WORT.

Eupatorium perfoliatum, Boneset, or Thoroughwort (Nat. Ord. Asteracea), is a very common indigenous plant, growing in wet grounds in every part of the United States. It has a perennial root, with numerous herbaceous stems, from two to five feet high, long, narrow leaves, perforated by the stems, and numerous white flowers, forming a flattened summit to the plant, which appear in August, continuing in bloom till October. The LEAVES and TOPS are the officinal portion. They have a faint odour, a strongly bitter taste, are soluble in water or alcohol, and contain a peculiar bitter principle, gum, tannic acid, resin, salts, and other matters.

Effects and Uses.-Thoroughwort is a stimulant tonic, diaphoretic, and expectorant, and in large doses proves emetic and laxative. It is a good stomachic in dyspepsia, and, from its combined corroborant, expectorant, and diaphoretic properties,

is an excellent remedy in epidemic influenza, and in the latter stages of pneumonia and bronchitis. It is also used with good

effect in rheumatism, and in intermittent, remittent and typhoid fevers. It should be given in infusion (a troyounce to boiling water Oj), f3ij of which may be taken cold, as a stomachic, three or four times a day, and in freer warm draughts as a diaphoretic.

ABSINTHIUM-WORMWOOD.

The TOPS and LEAVES of Artemisia Absinthium, or Wormwood (Nat. Ord. Asteraceae), a European plant, naturalized in New England, are ranked among the aromatic bitters, but are not now much employed. They may be given in infusion (a troyounce to boiling water Oj)-not officinal.
