When buying, you should see more and compare more, especially for the active ingredients. See if it has the specific data indicators. Secondly, wild Gynostemma is not better than artificial cultivation ones, you should attention to that. According to the data of research, different species of Gynostemma in various growing environment from different positions have different saponin level. The saponin content of Gynostemma in introduction and cultivation is higher than that of Gynostemma in wild herb and Ginsenoside content and amino acid content of Gynostemma in introduction and cultivation is higher than that of Gynostemma in wild herb. Because the purpose of artificial development is for improving the active ingredients of Gynostemma to better benefit human health.
The drinking method of Gynostemma:
1)The water is boiled. The saponin contained in Gynostemma is high in melting point which is dissolved at temperature of 80 degree centigrade.
2)Do not discard the first tea. The Gynostemma is different from traditional tea. The first tea kept bubbling up, and the bubbles are saponin. The total amount of saponin contained in Gynostemma is 4 times over that contained in ginseng. The saponin has not only the role of ginseng but also has another effect, clearing heat and removing toxicity with out the side effect of over use. So if you discard the first cup of tea, it is a super waste. And the saponins has been a monopoly of businessmen in Hangzhou.
