Why choose Jiaogulan Leaf from Thailand? Answers here by the growers. 1st Place Award for the Best Tasting Tea in Thailand – Thailand produces 20 metrics tons of tea a day (also 100 different herbal infusions) and is famous for oolong and black teas. When the Ministry of Agriculture and the Department of Public Health hosted a symposium to spread awareness of these products, our herbal, organic Jiaogulan leaf won 1st Prize for the Best Tasting Tea. Immortalitea Trademark- Gynostemma Pentaphyllum, 5 Leaf variety. Local names: Herb of Immortality and Sweet Tea of the Vine. Health Properties – Adaptogen, Anti-oxidant and immunity support. More than 30 years of study in China, Japan, Thailand. Studies began in USA and Europe 15 years ago. 100% Organic – We grow organically using mulch fertilizers. All Natural – our tea has no additives, no caffeine, no additives, no colorings, no flavorings, no sugar, no chemicals, no herbicides, no pesticides and is 100% GMP free. Sweet Tasting – most Jiaogulan has a medicinal and bitter after-taste, yuck! Our tea is slightly bitter and slightly sweet; subtle yet hardy/healthy/green. The longer is sits, the sweeter it gets. Leaves sink to the bottom of the cup; there is no need for tea bags. Quality Leaf and NO Tea Bags – We only use the rolled leaves in our tea and no stems over 1mm. Tea bag products commonly use stems and lower grade fillers. Powdered tea leaf oxidizes quickly, reduces shelf life and deteriorates the effectiveness of a fresh, healthy product. Effectiveness – our product has been tested for its strength. 1 gram (enough to make 1 cup) has highest concentration of active ingredients available in sweeter varieties of Jiaogulan.
