According to tea farmers who have many years of planting experience, how to distinguish Gynostemma pentaphyllum tea mainly depends on the smell, soup color, shape, taste and origin. This is naturally not a problem for regular customers who twist blue tea. However, for people who have just come into contact with Gynostemma pentaphyllum tea, the smell, soup color, taste and shape can't be recognized at a glance, so they always have to spend money to buy some lessons. However, starting from the origin of Gynostemma pentaphyllum tea, we can often avoid some traps.
Gynostemma pentaphyllum is distributed in China, India, Nepal, Sikkim, Bangladesh, Sri Lanka, Myanmar, Laos, Vietnam, Malaysia, Indonesia (Java), New Guinea, North Korea and Japan, and China is distributed in Shaanxi, Sichuan, Yunnan, Hubei, Hunan, Guangdong, Guangxi, Fujian and other places. Wild Gynostemma pentaphyllum is mainly distributed in Shengtangshan and Guangxi in Jinxiu County, Hunan Province.
The choice of Gynostemma pentaphyllum, from the origin, is of course the first one in Pingli, Shaanxi. There are only 13 species of Gynostemma pentaphyllum in the world, and there are 1 1 species in Pingli County, Shaanxi Province. Pingli County is located between 3142' ~ 34 45' north latitude and105 46' ~115' east longitude. It is located in the hinterland of Qinling Mountains, with unique climatic conditions and far from human cross-contamination sources.
Tested by pharmaceutical experts such as Professor Matsumoto of Tokushima University of Arts and Sciences, Professor Youdi of Feng Jingen University and Professor Odajima of Kanazawa University, the physical and chemical indexes of Pingli Gynostemma pentaphyllum rank first in the world, and its saponin content is as high as 12.2%. Therefore, Pingli County is recognized as the gold producing area of Gynostemma pentaphyllum in the world, and it is known as the "twisted valley".
It is unrealistic to distinguish the authenticity of Gynostemma pentaphyllum only from the origin, but knowing the best origin of Gynostemma pentaphyllum can at least avoid some common traps. If you want to distinguish the true from the false, you need to see more, learn more and drink more.
