It is said that as a tea, Jiaogulan would "benefit Qi, enrich the blood, keep the heart in good shape, and relieve uneasiness of body and mind". Gypenosides isolated from Gynostemma Pentaphyllum are widely used in traditional Chinese medicine, with beneficial effects reported in numerous diseases, including inflammation and atherosclerosis. The mechanism underlying these therapeutic effects is unknown but suppression of NO synthesis may be involved.
For those who want scientific information rather than Qi: Jiaogulan Extract can absorb UV (increasing the SPF of any sunblock), gypenosides can protect vascular endothelial cells from oxidant injury, and it may further slow the aging process.
