Nature's Pharmacy:
Ancient Knowledge, Modern Medicine

"Ancient humans have experimentally sampled many kinds of plants in their search for nourishment. Plants that were palatable were used for food; those with toxic or unpleasant effects were avoided or used against enemies; others that produced physiological effects such as perspiration, defecation, healing, or hallucination were saved for medicinal purposes and divination. Over a period of thousands of years, people learned to use a variety of plants as medicines for different ailments."
