What is thus exemplified in astronomy and astrology can be found in the story of every other science. After the knowledge of the stars, the next organized branch of information that might deserve the name of science related to plants. This, too, was introduced into medicine, and with more justification than astrology. Most of what was accomplished by early herbal medicine was, however, due to the influence produced on the mind rather than to any physical influence tending to correct pathological conditions. The shape and color of plants, their form, the appearance of their leaves, were all supposed to indicate medical applications for human ailments. The reason for their acceptance was entirely the ideas associated with the plants and not any definite therapeutic effect. Whatever good nine-tenths of all the herbal medication accomplished certainly was by means of the influence on the mind. We have abandoned the use of most herbal remedies in recent years, even many that are still retained in the pharmacopeia, because we have realized their physical incapacity for good.
