There is a kind of snake in Guangxi and Yunnan in China, which is black and white, and is called white snake. Agkistrodon likes to lick the dew on the leaves of a grass, hence the name Hedyotis diffusa. It has been stated in ancient medical books in China: Hedyotis diffusa, also known as Hedyotis diffusa, Spartina diffusa, and Eupatorium odoratum, mainly grows in Guangxi, Yunnan and other places in China. It is sweet and light in nature, and enters the liver, stomach and intestines, and has the functions of clearing away heat and toxic materials and helping digestion. Modern research also shows that Hedyotis diffusa can clear away heat and toxic materials, induce diuresis and reduce swelling, resist tumor and virus, and enhance human immune function.
Laoshan Hedyotis diffusa water is an alkaline drink prepared by adding Hedyotis diffusa extract and carbon dioxide into natural Laoshan mineral water through a special process. It not only retains many minerals beneficial to human health in Laoshan mineral water, but also perfectly integrates the functions of Hedyotis diffusa, effectively relieving alcoholism, protecting liver, nourishing stomach, detoxifying and clearing heat, so it can be called a treasure of healthy drinks.
Since the publication of 1962, the Laoshan Hedysarum Water has been selling well in Southeast Asia for 48 years and has been exported to more than 20 countries and regions, and has been praised as "a health treasure and a classic for health preservation" by foreign consumers. During his stay in China, Sihanouk, an old friend of the people of China and former Cambodian Prime Minister, drank the old mountain snake grass water every day. In 2000, during his visit to China, former Singaporean Prime Minister Goh Chok Tong named Laoshan Agkistrodon Grass Water. Laoshan Agkistrodon grass water is therefore known as "presidential drink" and "world famous drink".
