Treasure of the East is a woman- and AAPI-owned TCM herbal company based in Ithaca, NY, representing the biggest and most trusted granule supplier in China. 

Dr. Ann Wang, Founder 

Dr. Ann Wang, CMD, LAc, moved her practice from China to the US in the late 1980s. When she struggled to get the clinical results she was used to getting back home, Dr. Wang returned to China again and again, to bring back the best quality herbs for her clinic and her patients. Having served as faculty at China’s Academy of Chinese Medical Sciences before come to the US, Dr. Wang had been exposed to the best herbs available. She began introducing these treasures to Ithaca’s small but vibrant TCM community. As more patients improved, and more practitioners asked for these treasured herbs, it was time to make it official. In 1994, Treasure of the East began its operations as the first FDA-registered supplier of TCM granule herbs from mainland China. Now, Treasure of the East became a  major supplier of premium herbs for TCM practitioners nationally.


Dr. Wang's Integrative Medicine Center in Ithaca, NY was one of the first in the United States to truly integrate eastern and western medicine. The Integrative Medicine Center's care team included licensed acupuncturists/herbal medicine practitioners, MDs, licensed therapists, massage therapists, RNs, chiropractors and others.

In November 2022, Dr. Wang retired from practice. Today she continues to put her energy, expertise, and enthusiasm into Treasure of the East.

Teresa Williams, CEO
Like many immigrant children, Teresa started working with her family as a preteen, first at her mother's practice and then at Treasure of the East. Her involvement waned while she pursued her PhD in sustainable manufacturing (go bears!) and a career as a solar engineer and executive; but, as demand for Treasure of the East herbs grew, the company’s needs grew as well. So, in 2017, Teresa officially joined Treasure of the East in a full-time capacity, in charge of operations, sales, and marketing.

Witnessing the company’s evolution over the years, Teresa is incredibly proud of the team’s growth and cohesion. The team is constantly building on their clinical, technical, and creative skills, making Treasure of the East a gratifying place to work. H
aving worked in male-dominated fields (engineering, robotics, manufacturing) for so much of her career, Teresa especially loves interacting with the incredibly diverse array of healers, entrepreneurs, and educators that Treasure of the East serves.
