In China, there is a kind of snake, black and white, called white snake. Agkistrodon halys likes to lick the dew on the leaves of a grass, hence the name Hedyotis diffusa. It has been recorded in ancient Chinese medical books that Hedyotis diffusa, also known as Hedyotis diffusa, Spartina, and Eupatorium odoratum, mainly grows in Guangxi, Yunnan and other places in China. Sweet and light in nature, it enters the liver, stomach and intestine, and has the functions of clearing away heat and toxic materials and helping digestion. Modern research also shows that Hedyotis diffusa has the functions of clearing away heat and toxic materials, diuresis and detumescence, anti-tumor, anti-virus and enhancing human immune function.
Hedyotis diffusa water in Laoshan is an alkaline drink made by adding Hedyotis diffusa extract and carbon dioxide into natural Laoshan mineral water through a special process. It not only retains a variety of minerals beneficial to human health in Laoshan mineral water, but also perfectly combines the efficacy of Hedyotis diffusa, which effectively relieves alcoholism, protects liver, nourishes stomach, detoxifies and clears heat, making it a treasure in healthy drinks.
Since the publication of 1962, Laoshan Agkistrodon acutus water has been sold well in Southeast Asia for 48 years and exported to more than 20 countries and regions, and has been praised by foreign consumers as "the treasure of health care and the classic of health care". During his stay in China, Sihanouk, an old friend of China people and former Cambodian Prime Minister, drank the old snake grass water every day. In 2000, during the visit of former Singaporean Prime Minister Goh Chok Tong to China, Laoshan Mountain was named Agkistrodon Grass Water. Laoshan Agkistrodon halys grass water is also known as "presidential drink" and "world famous drink".
