Are Herbal Remedies the New Big Pharma?

Big Pharma is heralded for inventing new cures, but the courts are clogged with dangerous drug cases. Most of the world has used plant-based remedies for hundreds if not thousands of years. Here, there's plenty of skepticism, but Chris Kilham, professor of ethnobotany and explorer in residence at the University of Massachusetts, says herbal medicines are much safer than synthetic drugs.

"I feel badly for the people who suffer from the side effects and consequences of hazardous pharmaceuticals. It's antithetical to the Hippocratic Oath. I want to see people use safe, practical medicines. And the science on this is vast, deep. There's no question these things work.” – Chris Kilham, CNBC
