Patent Laws Drive Medicinal Development

The replacement of herbs with synthetic drugs is a relatively new phenomenon, less than a century old, born largely out of economic opportunities afforded by patent laws. Drug companies can't typically patent commonly used plants, but they can develop patented, proprietary synthetic drugs, often reaping billions in sales. Since the 1940's, chemists employed by pharmaceutical companies have developed novel synthetic molecules which have replaced plant medicines, and are sold both over the counter and by prescription.
