[club-moss, wolf's claw, natural order, lycopodiace^e.J This plant is found in Europe and North America, growing on stony, hilly forest land. The stem trails along the ground for several feet ; the leaves are crowded, small, linear-lanceolate, of a deep-green color. We use the pollen or powder, technically described as sporules. It forms a fine, soft inodorous, tasteless powder which adheres to the fingers, but repels water. It burns rapidly and is frequently used by stage managers for making artificial lightning. This powder has been considered inert; it is inert in the crude state, but when properly triturated with sugar of milk, medicinal powers of considerable importance are developed. The microscope has demonstrated the existence of oily matter in these sporules and it is possible that the medicinal action of the remedy depends, to a large extent, upon peculiar properties of this oily matter. The stems and leaves of the plant have also been used for medicinal purposes by physicians of the physiological schools. Provings of lycopodium have been made with the crude substance and with various triturations, both high and low. The former have given us mainly the effects of the drug upon the urinary apparatus ; the latter those upon the alimentary tract and upon the mucous membrane of the respiratory organs. The remedy is used in acute aud chronic diseases ; it is of partic- ular value in tedious diseases, rivaling sulphur, calcarea carbonica and others in its large sphere of usefulness. CEPHALIC GROUP. Lycopodium is credited in Allen's Encyclopaedia with nearly throe hundred head symptoms alone. The following are of particular interest : Pressing and throbbing pains in various parts of the head ; pressing headache on the vertex, worse from stooping ; dull pain in the forehead, as if the head were being compressed ; pain on the right side of the head or in the (right) temple. Confusion and heaviness of the head ; dullness of the head. Headache above the eyes in the morning. The hair becomes very gray and comes out.
