"Materia Medica From new" mentioned that Shayuan Zi can: "Tonify the kidneys, strengthen the yin, improve the essence, and see the eyes." ”
In the "Derivation of Materia Medica", it is said that it can "replenish the kidneys", from which we can see that Shayuanzi has the function of tonifying the kidneys. Modern medical research has proved that Shayuanzi also has the function of liver protection.

When Chinese medicine mentions the relationship between liver and kidney, it often uses a sentence to emphasize that "one glory is both prosperous, one loss is damaged", the liver is not good, the kidneys cannot be good, therefore, if you want to supplement the kidneys, you must make up for the liver and kidneys.
There are many medicinal herbs for liver and kidney supplementation, common ginseng, deer antler velvet, etc., but we all know that these are valuable Chinese herbal medicines, and the market price is prohibitive. But Shayuanzi makes up for this deficiency, it can be supplemented with liver and kidney, and the price is low, and it is a civilian medicine for liver and kidney supplementation.
In fact, many people will feel confused when mentioning the name shayuanzi, do not know what shayuanzi is, it also has a name, called white tribulus terrestris. There is also such a legend about Shayuanzi.
According to legend, during Li Longji's reign, he gave birth to a daughter, Princess Yongle, although named Yongle, but her physical condition has not been good, thin and small, her face is yellow and scorched, and she is often sick.
Li Longji could do nothing about his daughter's illness and asked many famous doctors to treat her fruitlessly.
When the Anshi Rebellion occurred, Li Longji fled with Yang Guifei, and Princess Yongle was separated from the royal family in the rebellion and was taken to the Shayuan area of Shaanxi by the grandmother, and a Daoist priest of the Oriental Zhenren took the princess in.
In order to avoid the princess's loneliness, Dongfang Zhenren let his daughter play with her, without the shackles of the court, the princess went to the wild every day to play, looking for white tribulus to soak in water to drink, and it didn't take long for the princess's dry yellow hands to become pink and tender.
After the war subsided, the imperial court commanded Princess Yongle to return to the palace, and before leaving, Dongfang Zhenren gave her a gourd filled with white tribulus terrestris, and asked her to take three or five grains of tea every day after she returned, which could ensure her good health.
When the princess returned to Chang'an, Xuanzong abdicated and her brother Emperor Suzong took power.
The princess presented the white tribulus to the emperor and elaborated on its beauty.
After Suzong tried it for half a month, he suddenly felt refreshed, deaf and clear-sighted, and a hundred times more energetic. Later, the emperor issued an edict calling the white tribulus terrestris Shayuanzi, and ordered Fengxiang County to pay tribute to Shayuanzi every year, and it also changed from a weed to a famous medicine.
