About Us

Tianjiang Pharmaceutical is the global market and technology leader in concentrated herbal extracts. Founded in 1992, Tianjiang was the first manufacturer of concentrated herbal extracts to receive China's Good Manufacturing Practice (GMP) certification for pharmaceutical products.  Since then, Tianjiang has developed 30 patents on the extraction, granulation, and packaging of Chinese herbal extracts.

Tianjiang engages in research partnerships with 22 Chinese medicine research universities and 26 leading TCM hospitals, and has lead the industry in the development of quality standards. Its TLC botanical fingerprint standards have been adopted by the China FDA as the standard for all Chinese herb producers.  Tianjiang, along with China Pharmaceutical University and Nanjing University, are the three parties invited by US Pharmacopeia (USP) to collaborate on the development of US standards for Chinese herbal extracts. 

Currently, Tianjiang produces 700 varieties of herbal extracts made from botanical roots, stems, barks, flowers, fruits, seeds, leaves, mushrooms, and more. Botanical materials are sourced directly from over 300 farms (including 66 of Tianjiang's own farms) to ensure quality from seed through finished product.

Treasure of the East is the first FDA-registered company to import granule herbs from mainland China, offering a complete line of granule extracts made by Tianjiang Pharmaceutical. For 30 years, Treasure of the East has served the American TCM community with over 500 varieties of single herbs and formulas. The herbs were initially brought to the US by Dr. Ann Wang, CMD, LAc, an acupuncturist in New York State and former faculty member at China’s Academy of Chinese Medical Sciences, for the benefit of her patients. However, demand grew rapidly by word-of-mouth in the Chinese-American TCM community and the Treasure of the East brand was born. 

We are exceptionally proud to serve American healthcare professionals, medical institutions, contract manufacturers, and health and wellness brands, as Tianjiang's federally registered general agent and US distributor. Ours is the only US brand authorized to use the Tianjiang name.
