Huang Jing, also known as Siberian Solomon’s Seal, is the dried rhizome of Polygonatum sibiricum. The Chinese Pharmacopeia describes it as an herb that tonifies Qi, nourishes Yin, fortifies the Spleen, moistens the Lungs and tonifies the Kidney. Its main active compound consists of three different solomonseal polysaccharides, and 3 types of oligosaccharides. It also contains saponins similar to those of Ginseng and Astragalus. Those with big, fleshy, yellow and transparent cross sections are considered as supreme.
In the Taoist tradition, Huang Jing is one of the most important of all tonic herbs. It is said to “make the body light, to benefit the Qi, and to clear the eyes. Its taste is sweet, and it has no poison.” Taoists believe that ingesting Huang Jing is a way to consume cosmic Qi of a strong Yang nature, which adepts expect to confer primordial Yang characteristics into their bodies. It can tonify all Three Treasures at a profound level.
