DR. PIERCE'S COMPOUND EXTRACT OF SMART-WEED. This quickly diffusible stimulant and genial anodyne we have spoken of under the head of Anodynes. But its medicinal properties equally entitle it to a place and mention under the class of stimulants. As a stimulant it spurs the nervous system and arouses the circulatory forces. Congestion of the lungs, liver, bowels, or uterus, embarrasses the functions of these organs. Frequently this congestive difficulty may be entirely obviated, and the circulation of the blood restored to the surface of the body, by the administration of a few doses of this pleasant remedy. Thus it often acts like magic in giving relief, promoting the circulation, and restoring the organs to their accustomed functional activity. Full directions accompany every bottle. TONICS. Tonics are remedies which moderately exalt the energies of all parts of the body, without causing any deviation of healthy function. While stimulants are transient in their influence, tonics are comparatively permanent. [Illustration: Fig. 139. White Poplar. ] WHITE POPLAR (_Liriodendron Tulipfera_), called also American Poplar, or White Wood. The part used is the inner bark. This is a mild but valuable tonic for domestic use. _Dose_--Of the infusion, from one-half to one ounce; of tincture, from one to two teaspoonfuls. CHAMOMILE (_Anthemis Nobilis_). The part used is the flowers. This is a mild, unirritating tonic. _Dose_--Of infusion (one-fourth ounce of flowers to a pint of water) one-half to one ounce. GENTIAN (_Gentiana Lutead_). The root is the part used. This is a favorite domestic tonic in many localities. _Dose_--Of powdered root, five to ten grains; of the tincture, ten to twenty drops; of the fluid extract, five to ten drops, four or five times a day. NUX VOMICA (_Strychnos Nux Vomica_), or Dog Button. This is a powerful tonic. It increases innervation and is particularly valuable in cases marked by feeble circulation and general impairment of muscular power. In overdoses it is poisonous, and hence must be employed with much caution. _Dose_--Of the tincture, three to five drops; of the fluid extract, ONE TO THREE DROPS. WILLOW (_Salix Alba_). Willow is a tonic and an astringent. _Dose_--Of the decoction, from one to two fluid ounces; of the concentrated principle, Salicin, from two to four grains. [Illustration: Fig. 140.

Dogwood, also known Boxwood, is tonic, astringent, and slightly stimulant. _Dose_--Of the solid extract, from three to five grains; of the infusion, from one to two ounces; of the fluid extract, from ten to twenty drops. WAFER-ASH (_Ptelea Trifoliata_), also called Swamp Dogwood. The bark is used. This is a pure, unirritating tonic. _Dose_--Of tincture, one-half to one teaspoonful; of fluid extract ten to twenty drops; of the infusion, one to two fluid ounces. [Illustration: Fig. 141.
