1. Raw herb selection
Cleaned and prepared according to the specifications of the Chinese pharmacopeia. The Chinese Pharmacopeia is China's official and complete list of all drugs related to western and Chinese medicine, including functions, safety testing etc.
2. Water-based extraction
Extracted with purified water, with consideration of decoction time, temperature, water-herb ratio and concentration ratio to optimize extractions.
3. Filtration and concertation
Low temperature vacuum concentration and filtered extracts are used as well as strict monitoring to ensure consistency in products.
4. Spray drying
Using their own drying technique to dry heat-sensitive materials ensuring herb active ingredients are not destroyed.
5. Essential oil re-introduction
Previously extracted essential oils are used to increase herb efficacy while infusing extractions with their natural aromas.
Dry powder or fine crystalline materials are smashed and adjusted to particle size and sieved.
7. Quality control
Concentration ratio, dissolubility, bacterial levels, heavy metals, pesticide residue etc. are examined. Chromatography is used to determine levels of active ingredients within extracted granules and thin layer scanning used to identify fingerprint codes of each botanical.
8. Final Check
Once quality inspections are passed, granules are bottled and packaged into finish products as well as one final check from personnel under strict GMP specifications.
Finished products stored in a computer-controlled warehouse monitoring temperature and other factors within the warehouse, before being shipping out to their final destination!
