Mark Pedersen is a research chemist who specializes in herbal chemistry. He graduated from Brigham Young University in Chemistry and Geology in 1982.

Since then, Mark has been active in herb research, putting an emphasis on "What Works" since he battles a chronic digestive disorder.

He is the author of Nutritional Herbology (1987) and Nutritional Herbology Vol. II (1990). Both are cornerstones of the modern herbalist's reference library. These two works have been revised and condensed into Nutirional Herbology, A Reference Guide to Herbs.

Mark is married to Kellie Ann Magnum. They live with their three children in Utah.
