In this great article by Dr. Weil, he argues that plants (as in herbs) are better than pharmaceutical drugs to treat illness.
Western medicine holds that when a plant shows bioactivity in humans, we must attribute that single effect to a single compound in the plant. We label that the ”active principle”, isolate it, synthesize it, and make a pharmaceutical out of it. The primary reason we do this is because it makes drugs far more profitable for drug companies: isolating and synthesizing a single molecule allows a drug company to patent that molecule. (Natural compounds aren’t patentable). However, it is clear that herbs are very effective clinically, and using the whole plant (medicinal herbs) is often more effective and less expensive. Herbs really work, try them!
