 Doctors are skeptical of the ability of plant foods to treat disease. We have no problem believing a drug like lovastatin can lower cholesterol, but red yeast rice? Come on! It has been used in Chinese herbal medicine for over a thousand years, but what did they know back in the Tang dynasty in the year 800? But guess what's in red yeast rice? Lovastatin? Literally the exact drug. Instead of us synthesizing it in a lab, some purplish mold synthesizes it on rice and has it since forever. Now the drug levels in the moldy rice are too variable to be reliable, so I don't recommend anyone take red yeast rice supplements. I don't recommend people take lovastatin either. I recommend eating healthy enough that you don't need either one. But it is an illustration of the power of plants, or in this case, a fungus. Doctors prescribe diabetes drugs like candy, even though some may increase the risk of heart failure, heart attacks, and death. But at the same time, are skeptical that cinnamon could possibly help with blood sugar, because it's just some dried bark scraped from some tree? Well guess what taxol is? The revolutionary chemotherapy drug that's routinely used against a half a dozen human cancers. It's some dried bark scraped from the Pacific U tree. Now we just grow tree cells in a tank and make it that way. But originally, they were just scraping thousands of trees. Still don't think plants can be powerful? This is where cocaine comes from, morphine. This makes a glaucoma drug, anesthesia. This shrub cures malaria. This is where aspirin comes from, digoxin, colchicin, quinine, ipecac. This is where we get a drug to treat emphysema, Alzheimer's, Parkinson's. Periwinkle is what we use to treat childhood leukemia, even though on the bottle we call it vincristi. In the Middle Ages, they rubbed moldy bread into infected wounds. It was a staple European folk remedy. What quacks, until a couple hundred years later when penicillin went on to become the greatest discovery in all of medicine. Thanks to a moldy cantaloupe found in a market in Peoria, Illinois, no joke, the United States went from having just enough penicillin in 1942 to treat 10 people to 2 million doses in time for the invasion of Normandy. Over the last 25 years, about half of new drug discoveries have come from natural products. This can powerfully affect our health.
