Xi'an sits at the start of the ancient Silk Road and in one of China's richest regions for traditional herbal medicine. We combine that raw-material advantage with university-grade research.
Our two standard factories run 4 standard production lines and 2 pilot lines, plus a GMP-standard workshop. Pilot lines let us scale your custom formula from lab gram to commercial ton without changing the process.
Gas chromatography, HPLC and ultrasonic extraction equipment allow us to verify marker compounds such as icariin, lycopene or GHK-Cu purity in-house before every shipment — not just once per year.
Every lot is tested for identity, assay, microbes and heavy metals; COA ships with the goods.
18 senior & mid-level technicians and 5 licensed TCM pharmacists in a 30-person team.
Most powders start from 1 kg so R&D, pilot and launch orders move quickly.
99% message response rate with replies typically within two hours across time zones.
