One important advantage of therapies from the natural world comes from nature's heroic investment in research and development. Millions of species on this planet have spent millions of years developing chemical therapies using trial-and-error science — that is, evolution — to address many of the health issues for which we humans take medicine. Non-human species also get cancer, infections and diseases of inflammation. So they have developed their own chemotherapies, antibiotics, antivirals and anti-inflammatory drugs. Millions of years, millions of species, trillions of hours. That's a commitment to innovation.
