We have been trying to source this dried plant for a while, with it being either too expensive or having to take too large a quantity. However, this new wonder-plant is now in stock and at the right price. Jiaogulan, it’s pronounced as Jee-OW-goolan Gymnostemma pentaphyllum, is widely distributed in Southeast Asia and is a climbing vine from the cucumber family. It is best known as an herbal medicine reputed to have powerful antioxidant properties, increasing longevity, and lowering cholesterol, regulating high blood pressure and strengthening immunity. Until recently it was a locally known herb used primarily in mountainous regions of southern China and Northern Vietnam, where it was described by the local inhabitants as the ‘immortal herb’, due to the inhabitants having a history of unusual longevity. As this is a new discovery there are lots of opinions on brewing temperature and steeping time. I’ve gone 80oC for 2 minutes and re-infuse as many times as possible.
It goes without saying that if you're pregnant (or are under the doc for anything) caution should be exercised with herbal decoctions.
