Herbs for herbal teas were gathered in Altai, one of the most ecologically-clean areas on the planet. Each grain of TianDe herbal teasgives the maximum of useful elements when brewed.
Precious properties of Altai herbs are preserved thanks to the innovative processing of raw materials: it is known that vitamins are destroyed when heated to temperatures above 70 C.
This is excluded when TianDe teas are produced. Herbs are processed under low pressure and the optimum temperature, which increases the degree of extraction in case of repeated brewing (as compared to to teas not subject to such processing). Herbal teas bags have a three-layer package, including sachets, a box and a film. This reliably protects vitamins, as well as plant micro and microelements.
