Yunxiang Organic Oolong Tea Base To kill pests - Adopt the organic pesticide developed by the Science Academy of China and Northwest Agricultural University To fertilize - Apply farmyard manure and super biological organic fertilizer app roved by EEC. Without accelerating culture by chemical fertilizers, the organic tea has a longer growing period than other teas aided by chemical fertilizers. Its picking maturity is delayed 20 days as compared with that of other teas. Therefore, there are only three picking seasons for the organic tea and its output is only two third of that of other teas. Yunxiang Co. adopts the primitive tea making techniques for its organic Oolong tea making and with equipment of modern technology, free from any metals. Therefore, the organic tea manufactured in this way tastes mellow and refreshing. As no spice is added, the organic tea gives you a pleasant, delicate, and lasting taste with sweet smell. Through its hard work in the past few years, Yunxiang Co. has cultivated health teas completely safe for consumers of different groups in different health conditions (including patients sensitive to chemical residues and pregnant women)
