At present, "Zuotai" technology is the exclusive national patent technology of Xizang Autonomous Region Tibetan Pharmaceutical Factory (national patent number ZL88 107006.8), which belongs to the national first-class confidential science and technology project, and is widely used in "Manna" series products such as "Seventy Flavor Pearl Pills, Renqing Changjue, Zuozhu Darcy", which is not available from any other manufacturer. Because 70-flavor Pearl Pills and Renqing Changjue are well-known at home and abroad, and the genuine products are in short supply, some Tibetan pharmaceutical factories are driven by interests to produce some 70-flavor Pearl Pills and Renqing Changjue that are not approved by the state for external sale. Because there is no "sitting on the stage" process, the product effect is greatly reduced. The majority of patients are requested to look for "Ganlu" brand 70-flavor pearl pills and Renqing Changjue produced by Xizang Autonomous Region Tibetan Pharmaceutical Factory when purchasing, and beware of counterfeiting when purchasing through designated channels.
Xizang Autonomous Region Tibetan Medicine Factory is a traditional Tibetan medicine manufacturer with the longest history, the strongest technical force and the largest scale in China. As the birthplace of authentic Tibetan medicine, its predecessor was the preparation room of Yaowangshan Medical Welfare Institute in Lhasa, which was founded in A.D. 1696. It has a history of more than 300 years. Known as the "pharmacist cloud city", it has the national patent of the best "Zuotai" technology in Tibetan medicine processing. More than 350 varieties can be produced, and the Tibetan medicine produced is famous for its authentic formula, authentic materials and exquisite technology. In addition, the "Ganlu" trademark of Xizang Autonomous Region Tibetan Pharmaceutical Factory is the only "China well-known trademark" of Tibetan medicine. In June this year, Tibet Tibetan Medicine Administration authorized Xizang Autonomous Region Tibetan Medicine Factory and Tibet Entry-Exit Inspection Bureau to apply to AQSIQ for six kinds of Tibetan medicines, such as Ganlu brand 70-flavor Pearl Pill, Renqing Changjue and Zuozhu Darcy, as "national geographical indications" products.
