Honoring His Legacy

Dr. Timothy Yeh

Dr. Timothy Yeh — President of Yeh Center of Natural Medicine

Dr. Timothy Yeh was the President of the Yeh Center of Natural Medicine in Upland, California, and a recognized pioneer of natural medicine in the United States. He integrated physics, biology, and chemistry with both Eastern and Western medical traditions to diagnose and heal at the root-cause level.

Trained under descendants of royal physicians from the Qin and Ching Dynasties, Dr. Yeh began his medical studies in 1950 and spent over five decades refining his approach. He personally traveled the world to source premium herbs traced to formulations with over 4,000 years of historical use.

His work was recognized in Who's Who in California and Who's Who in the World, and he was named 2004 Physician of the Year by the Physicians' Advisory Board. Together with Dr. Pearl Yeh, he co-founded the Yeh Center, Yeh Herbs Manufacturing, and Natural Medicine International.
