Upon its publication more than a decade ago, Dr. James Duke's The Green Pharmacy quickly set the standard for consumer herb references. A favorite of laypeople and professionals alike, the book sold more than a million copies and solidified the author's reputation as one of the world's foremost authorities on medicinal plants.

In The Green Pharmacy Guide to Healing Foods, Dr. Duke turns to the broader and even more popular subject of food as medicine, drawing on more than thirty years of research to identify the most powerful healing foods on earth. Whether he is revealing how to beat high cholesterol with blueberries, combat hot flashes with black beans, bash blood sugar spikes with almonds, or help relieve agonizing back pain with pineapple, Dr. Duke's food remedies help treat and prevent the whole gamut of health concerns, from minor (such as sunburn and the common cold) to more serious (like arthritis and diabetes).

Dr. Duke has assigned a rating to each remedy, according to his evaluation of the available scientific studies and anecdotal reports. Many of the healing foods recommended here are proving so effective that they may outperform popular pharmaceuticals—minus the risk (and cost).
