"Zuotai" is one of the four major traditional medicines in the world.

Zuotai is also called "Mercury Refining Method", and in Tibetan it is called "Zuozhu Qinmo"

"Zuotai is an indispensable raw material for precious Tibetan medicines such as Seventy Flavor Pearl Pills and Renqing Changjue.

Although Qinghai is an important place for the inheritance of Tibetan medicine, Dorje told me that more than 40 years ago, Qinghai did not have professionals who mastered Zuotai’s processing skills.

After that, Qinghai Province invited the Tibetan medicine master Tsoru Jiro, who had saved Zuo Tai from loss, to teach in Qinghai.

Dorje was allowed to follow the only "Master of Traditional Chinese Medicine" Nima in Qinghai to pass on Zuo Tai's crafting skills

In addition, the classics also record another cleaning step made by Zuo Tai, that is, adding three pungent powder to mercury, putting it in a zongzi skin bag and tightening it, rubbing it with hands for three days and nights.

In order to solve the problems of long processing cycle, easy poisoning of personnel, and laborious and time-consuming manual grinding, Qinghai Provincial Tibetan Hospital has taken the lead in designing and introducing ball mills and electric stoves to make processing even more powerful

At the end of the process, add gold ash, silver ash, copper ash and other "eight golds and eight mines (ash)", add the same amount of processed sulfur to synthesize, supplemented with pomegranate seed water, etc.

"Zuo Tai who does not have golden ash cannot be called Zuo Tai

It is reported that the "Seventy-flavored pearl pill saitai craftsmanship" is also a national "intangible cultural heritage" project in China

According to Dorje, the Qinghai Provincial Tibetan Hospital produces Zuotai once every two or three years, with a limit of 380 kg to 400 kg per shot, and the price per gram is more than 20 yuan

Mercury is volatile, and Dorje said that twenty to thirty professionals who prepare each time have to wear protective shields, supplement protein daily, and drink a certain amount of alcohol to enhance metabolism and reduce the risk of poisoning during the production process

"The mercury in a beverage bottle is difficult for the first hand to pick up, but after concocting, Zuotai can float on the water

Even so, the use of Zuo Tai has caused the public to question the safety of compound Tibetan medicines such as Seventy Flavor Pearl Pills

The results of the previous clinical safety evaluation of Qishiwei Zhenzhu Wan by the Northwest Plateau Institute of Biology, Chinese Academy of Sciences showed that although the short-term administration of Qishiwei Zhenzhu Wan increased the body's excretion burden on mercury and lead, it did not cause liver and kidney function.

Nowadays, "Master of Traditional Chinese Medicine" Nima and others have discovered that the origin of 64 kinds of excipients, the quality of nature and taste, the dosage, the proportion of preparation, and the time and frequency of cleaning and milling, etc.
, have all been It directly affects the quality of Zuotai and should be regulated after qualitative and quantitative
.

Dorje Cairang said that at present, there are no problems with Zuo Tai's inheritance, but production should be regulated, and Zuo Tai's processing specifications and quality standards should be formulated, so that Zuo Tai will last forever
