Tag Alder (Alnus Rubra). This shrub grows in swamps and other damp places, in northern United States. The bark is alterative, emetic, and astringent. It is used in scrofula, secondary syphilis, herpes, impetigo, and other skin diseases. Preparations. Fluid extract, dose, one to two drams ; infusion, two ounces to a pint of water, dose, one to one and a half ounces; alnuin, the active principle, dose, one to two grains.

Tansy ( Tanacetum Vulgare). Tansy is a perennial herb having tonic, emmenagogue, and diaphoretic properties; the cold infusion being tonic, and useful in dyspepsia, wind in the stomach, jaundice, and worms; the warm infusion, diaphoretic and emmenagogue. Dose of the infusion, from one to three fluid ounces, two or three times a day.

Tar (Pix Liquida). The medicinal qualities of tar are like those of turpentine, and it is sometimes used in old chronic coughs and bronchitis. The vapor of boiling tar was once thought to be very serviceable in bronchial diseases, when inhaled. Doubtless it is useful in some cases, but its virtues have been extolled above their merits. In the form of ointment it has real efficacy in scald head and tetter.

Thimbleweed (Rudbeckia Laciniata). The whole of this herb is balsamic, diuretic, and tonic, and in the form of decoction, used freely, is said to have been found useful in some urinary complaints, as Bright's disease, strangury, etc.

Tobacco (Nicotiana Tabacum). The leaves of tobacco are acrid, narcotic, and poisonous, and are chiefly used in the form of ointment, in skin diseases, etc. Its poisonous qualities, however, render it dangerous when much used, even externally. Nervous people should not smoke. Chewing is not only an unhealthy, but a disgusting habit.

Trailing Arbutus (Epigima Repens). This grows in sandy woods and rocky soils, its flowers appearing in early spring, and exhaling a spicy fragrance. The leaves are diuretic and astringent, and are very useful in gravel, and most diseases of the urinary organs, being regarded in some cases superior to uva ursi and buchu. Preparations Fluid extract, dose, one to two drams; infusion, dose, two to three ounces.

Tapioca(Janipha Manihot, Fig. 23 8). This plant grows in the West Indies and Brazil. It is cultivated chiefly on account of the root, which is largely used as an article of food, particularly for the sick, or rather for those recovering from sickness. The starch which it contains is separated by washing, scraping, grating, and grinding, and is in the form of hard, white, rough grains. It is prepared for use by boiling; and, in debility and low forms of disease, may have the addition of wine, nutmeg, or other aromatics.

Tulip Tree (Liriodendron Tulipifera). This is a large and elegant tree growing in many parts of the country, and called poplar and white poplar. The bark of the root is aromatic, stimulant, and tonic, and in warm infusion, diaphoretic. It is used in fever and ague, chronic rheumatism, and chronic diseases of the stomach and bowels. Dose of the powdered bark, from a scruple to two drams; of the infusion, from one to two fluid ounces.

Turkey Corn (Corydalis Formosa). This perennial plant is called wild turkey pea and stagger weed, and grows in rich soils in the Southern and Western States. The tuber, which is the medicinal part, should only be collected when the plant is in flower. It is tonic, diuretic, and alterative. It is much valued as a remedy in syphilis and scrofula. Preparations. Fluid extract, dose, ten to thirty drops; tincture, three ounces to a pint of diluted alcohol, dose, half a dram to two drams; corydalin, the active principle, dose, half a grain to a grain. A valuable alterative for syphilis is made by uniting eight grains of corydalin with ten grains of hydrastin, and dividing into twelve powders. Dose, one powder three or four times a day.

Turmeric (Curcuma Longa). This is a native of the East Indies and Cochin China. The root is a stimulant aromatic and tonic, somewhat Eke ginger, employed in debilitated states of the stomach, etc. Preparations. Fluid extract, dose, two or three drams; tincture, two ounces to twelve ounces of diluted alcohol, dose, one and a half to two ounces; infusion, dose, two to four ounces.
