Introducing The Chinese Herb of Immortality - Jiaouglan (Gynostemma pentaphyllum) In the first Chinese nationwide census, demographers noted an unusually large number of people over age 100 in two Southern provinces. After years of study the researchers concluded that the only difference between people in these provinces and elsewhere was the traditional routine consumption of a locally grown herbal tea called jiaogulan. Now you too can benefit from the life enhancing power of this little-known herb. Why Immortalitea Jiaouglan is the bestWe specialize in jiaouglan. It is the reason we are called Immortalitea.
