Dendrobium is a common Yin tonic and one of the most valuable herbs in Yin tonic medicine. The Taoist medical classic Daozang, which was written more than a thousand years ago, lists Dendrobium as the first of the “Nine Chinese Immortal Herbs”, and the folk call it the “life-saving immortal herb”. There are many varieties of Dendrobium, for example, Dendrobium cinnabar, Dendrobium purple skin, Dendrobium copper skin, Dendrobium just section, Dendrobium grass skin, Dendrobium stone skin, Dendrobium iron skin, etc. The price and efficacy also vary. The story of Dendrobium and celebrities The only female empress in Chinese history, Wu Zetian, lived a long and beautiful life at the age of 81. Her hair is still black, lubricious and lustrous, and her skin is still white, rosy and elastic after she reached her prime. According to the classic records, Wu Zetian’s recipe for skin care focuses on nourishing blood and nourishing yin at the same time. The formula was offered by Ye Fashan, a famous health master of the Tang Dynasty and an imperial doctor of the Six Dynasties, with saffron as the ruling medicine and Dendrobium ferruginum and Ganoderma lucidum as the ministerial medicine, with the effects of nourishing blood and nourishing Yin, benefiting Qi and invigorating Blood, clearing the five organs, balancing Yin and Yang, soothing Qi and Blood, and improving the physiological functions of the body. Under the nourishment of this formula, Wu Zetian was glowing and radiant every day, and even in her twilight years, she remained beautiful and ageless, truly achieving the role of beautiful face, delaying aging and prolonging life, so experts called it the first formula for ancient beauty. In the folklore, when the dying patients who are extremely weak are dying, people often feed the fresh Dendrobium ironbark thick juice into their mouths, which can often revive them, so there is the saying of “life-saving herb”.
