Yuho Hayashi, Ph.D., L.Ac. (Owner)


Ancient Prescription was born out of Dr. Hayashi’s life-long work in natural sciences, and of her idealism for healthcare that is sincere, gentle, yet “amazingly” effective.

Originally from Japan, Dr. Hayashi has lived and studied in Switzerland, France, and US. She completed her undergraduate degree in biochemistry at New York University, then her graduate studies in space physiology at NASA Johnson Space Center and Ph.D. in cancer biology at The University of Texas MD Anderson Cancer Center in Houston, TX. All the while, she also learned to fly airplanes as a commercial pilot.

Through her extensive experiences in academic medicine, Dr. Hayashi developed her idea of medicine to resonate more with a traditional holistic approach than with modern technology-centered, protocol-based, efficiency-focused ones. It is on the basis of such ideology that she practices time-honored acupuncture and herbal medicine.

At Ancient Prescription, Dr. Hayashi strives to live by the attitude of “一期一会” (pronounced ichi go ichi e), meaning “each moment, only once in a lifetime”. She is dedicated to help people find real and lasting relief from feeling and being sick; and to be a trustworthy advocate for them for the benefit of their long-term health.
