The flower is tonic and astringent. Dr. Beach prescribes the rose water in connection with the pith of young sassafras twigs, in ophthalmia, or inflammation of the eyes. PENNYROYAL. Found all over the United States, and in Canada. It is gently stimulant, produces universal perspiration when taken in large quantities, warm, and we consider it the best drink to accompany the lobelia emetic. In cases of sudden suppression of the menses, a tumblerful of this drink, with an even teaspoonful of black pepper, powdered fine, sweetened and drank warm, after soaking the feet in weak ley, will rarely fail producing the desired effect. It is useful to qualify, or mix other medicines for sickness at the stomach, colds, &c., and may be drank freely. BLUE FLAG. Found throughout the United States, by the side of streams and wet places. It flowers in June, has a very handsome blue flower; grows about two feet high. The Oneida Indians make much use of this root for the cure of rheumatism. Make a strong tincture of the blue flag root, by putting it into spirits, or alcohol; let the patient take a teaspoonful three times a day, after eating, increasing the dose gradually. If it should produce slight pains in the head and breast, take less at a time. BEGGAR LICE. The virtues of this plant has never, to my knowledge, been thoroughly understood. As a nervine in all female difficulties, and a valuable medicine when used for any derangement in the monthly courses, it has not many equals; it will remove pain immediately, and quiet the nerves. DIRECTIONS.--Take a handful of the flowers and leaves, and half the quantity of tanzy; make a good strong tea, and take a quantity on going to bed, if you can; if not, take it, but do not go out in the cold. The best time is bed time. SINGLE-CELLED BERRY. Grows in hedges, and along the road sides, in almost every part of America; flowers in July and August; the berry contains three irregular shaped seeds. MEDICAL VIRTUES.--A decoction of the berries and roots, has been found most efficacious in curing dropsies. PREPARATION.--Boil two ounces of the dry root, in two quarts of rain water, down to one half, and strain the liquor. In dropsy, a gill of the decoction must be taken morning and night. A gill of the juice made from the inner, or green bark, works powerfully, both upwards and downwards, and has frequently cured dropsies. One ounce of the inner bark, dried, and one ounce of the dry roots, may be boiled in four quarts of rain water, down to two quarts; a teacupful, taken three times a day, works powerfully as a diuretic, and is an excellent remedy in suppression of the urine.
