Quality Assurance

Treasure of the East® herbal formulas are full-spectrum, pharmaceutical-grade, and extracted only with purified water to replicate a traditional decoction. They are produced by Tianjiang Pharmaceutical, the world's largest producer of herbal granules, in a facility that is fully automated and computer-controlled to ensure quality and reliability. Products are tested extensively in Tianjiang's CNAS National Laboratory, yielding high-precision data regarding each herb's identity, origin, concentration of effective components, heavy metal and pesticide residues, and proper dosage in concentrated form. Tianjiang's production protocols for concentrated herbal extracts have been internationally recognized and adopted into the pharmaceutical and food standards of the China Food and Drug Administration.



To ensure a safe, consistent, and high-quality product, TianJiang Pharmaceutical has developed a number of standardization protocols that regulate the process of converting raw herbs into concentrated granule herbs. These protocols prescribe the use of specialized technology to control for each herb’s identity, origin, concentration of effective components, optimal binding material, and the proper dosage in concentrated form. To date, TianJiang has established quality standards for over 600 granule herbs. TianJiang' s standardization protocols for concentrated granule herbs have been internationally recognized and adopted as the pharmaceutical industry’s national standard in the People’s Republic of China.
