Opinion: Gynostemma is the plant gynostemma of the family Huludaceae. This small grass, millions of years ago, has been growing in the high mountains of the mountain rushes in the long years of recuperation, is looked down upon by the people of the weeds. In the folk application although there have been more than a thousand years of history. Mainly used for anti-inflammatory detoxification, cough expectorant. Now mostly used as tonic and strong medicine. Not in the medical profession has attracted enough attention. In the Chinese medicine store basically did not have this medicine, until 1976 Japanese scientists first successfully extracted from the gynostemma saponins, its main ingredient, and its pharmacological effects of a large number of studies. In the last two decades scientists from all over the world have been exploring the effects of the plant, and American scientists conducted extensive research on gibberellins in the nineties, and found that the ingredients contained in each of the plants in its family are not exactly the same. And we from the eighties onwards first found that the plant's good seed - wild nine-leaf gibberellic acid, followed by seven-leaf gibberellic acid, after many years of research, found that gibberellic acid has three-leaf, five-leaf, seven-leaf and nine-leaf four major categories, each - and there is a superiority in the inferiority of each category. Various types of human medicinal and health care functions differ greatly, three leaves, five leaves classified as inferior varieties. Its gibberellin saponin content of the lowest only 1.5% a 1.% 3%, cold taste bitter, while the seven-leaf class of bitter with sweet with 3%, sweet seven-leaf class of 4% -7%, nine-leaf class of gibberellin saponin 8-12%, and gibberellin on the human body has a wide range of special effects of gibberellin saponin, has not yet been found on the other plant on the The human body has a wide range of pharmacological and health functions, can be compared with gibberellin. Seven-leaf nine-leaf two categories also have bitter. Its function is much stronger than the three-leaf and five-leaf, the good kind of gibberellic acid is cool in nature and sweet in flavor. Modern gibberellic acid research experts and medical experts basically write gibberellic acid as sex cold, taste bitter research is inferior varieties. It is no wonder that people also basically as long as it is gibberellic acid have the same role of misperception, there is no superiority in the inferiority of the points, that fish eyes mixed up.

Wild nine-leaf gibberellic acid, is the king of gibberellic acid, shock cool, sweet taste, it grows naturally at an altitude of more than one thousand meters in the mountain rush in the sparse forests, mountain cans, rock piles and the roadside, etc., for years and years to pick the essence of the sun and the moon, subject to the grace of the clouds and rain and dew, is a rare and valuable plants, containing gibberellin saponins up to 8% -12%, the longer the growth of the years of the higher the saponin content! The longer the years of growth, the higher the saponin content, our country has: "Millennium ginseng is a national fixed" said. Gynostemma is also so, its medicinal and health care function is particularly strong. Excellent varieties of pressure in low altitude flatland planting, its efficacy to be greatly reduced.
