Clinical research
Antioxidant
Jiaogulan has been found to increase superoxide dismutase (SOD), which is a powerful endogenous cellular antioxidant. Studies have found it increases the activities of macrophages, T lymphocytes and natural killer cells and that it acts as a tumor inhibitor.[10]
Adaptogen
Jiaogulan is known as an adaptogen, which is an herb reputed to help the body to maintain optimal homeostasis[11] by balancing endocrine hormones, the immune system, the nervous system, and other biological functions. Its chemical constituents include the triterpenoid saponins gypenosides which are closely structurally related to the ginsenosides from the well-known medicinal plant ginseng.[12] Most research has been done since the 1960s when the Chinese realized that it might be an inexpensive source of adaptogenic compounds, taking pressure off of the ginseng stock. Adaptogenic effects include regulating blood pressure and the immune system, improving stamina and endurance.[13] Jiaogulan is also believed to be useful in combination with codonopsis for jet lag and altitude sickness.[8]
Blood pressure
The adaptogenic nature of gypenosides have been found lower hypertension and raise hypotension, keeping blood pressure in a normal range. Laboratory tests demonstrate that jiaogulan stimulates the release of nitric oxide, causing blood vessels to relax; this is one proposed mechanism by which jiaogulan reduces high blood pressure.[14] In a double-blind study, gypenosides administered to with Grade II hypertension showed 82% effectiveness in reducing hypertension, compared to 46% for ginseng and 93% for Indapamide (a hypertension medication).[15]
Cardiovascular functions
Animal studies as well as clinical testing on humans suggest that jiaogulan, when combined with other herbs, has beneficial effects on cardiovascular system, increasing heart stroke volume, coronary flow, and cardiac output while reducing the heart rate, without affecting arterial pressure.[16][17]
Cholesterol reduction
Numerous clinical studies in Chinese medical literature have shown that jiagolan lowers serum cholesterol,[18] triglycerides, and LDL (the "bad" cholesterol) while raising HDL ("good" cholesterol) levels, with reported effectiveness rates ranging from 67% to 93%.[19]
Diabetes
Gynostemma pentaphyllum tea has been used in a Randomized Controlled Trial to treat type 2 diabetic patients.[20] It has shown potential as a hypoglycemic treatment to reduce blood glucose.[21]

y a pas a dire, t'as la main verte,  ... un as de la pouponnière !  

ps : avec cet étonnant "été indien" (température de Juillet au mois d'octobre),
j'ai des spontannées (tomates et aubs) qui se sont mises à pousser dans ma jardinière !!!
(sans doute des graines jetées dans le compost) ...
j'ai beau leur expliquer que ce n'est pas le moment, elles n'en font qu'à leur tête !!!  
... et j'ai aussi des rejets de lycium, d'un plant presque adulte, je vais en avoir 4 ou 5 nouveaux,
juste en laissant faire dame Nature .
