Huang Jing, known as "Huang Zhi" in ancient times, is listed as one of the "immortal medicines" in the Taoist classic "Daozang", and is considered to be a panacea that can prolong life and immortality. Legend has it that the underground stems of Polygonatum polygonatum are processed through nine steaming and nine drying processes, which can exert its maximum medicinal effect. After this special process, Huangjing has a variety of effects such as nourishing blood and yin, nourishing the spleen and stomach, moistening the lungs and relieving cough, delaying aging, etc., so it is widely used in traditional Chinese medicine clinics.
The medicinal value of Polygonatum polygonatum is very rich, its taste is sweet, the nature is flat, and it can enter the spleen, lungs and kidney meridians. In traditional Chinese medicine theory, Huang Jing is believed to be able to nourish the central qi, moisten the lungs and nourish yin, and has a good relieving effect on symptoms such as spleen and stomach weakness, indigestion, lung deficiency and cough. At the same time, a variety of nutrients contained in Polygonatum polygonatum, such as polysaccharides, saponins, flavonoids, etc., also have high medicinal value. Modern pharmacological research has also shown that Polygonatum polygonatum can improve immunity, lower blood sugar, regulate blood lipids, anti-aging, etc., and is a very precious Chinese medicinal material.
In addition to its medicinal properties, Huangjing also has an important place in Taoist practice. Many Taoist practitioners consume yellow essence to achieve the effect of strengthening the body and cultivating the mind. They believe that yellow essence is the "surplus food of the immortals", which can provide enough energy and nutrients to help practitioners better cultivate their bodies and minds, and achieve a state of harmony between body and mind. Therefore, Huang Jing also has a very important position in Taoist culture.
In short, Polygonatum polygonatum is a very precious Chinese medicinal material, with rich medicinal value and profound cultural connotation. Whether from the perspective of TCM clinical practice or Taoist practice, Huangjing is a valuable resource worthy of in-depth study and utilization. With the continuous deepening of modern medical and pharmaceutical research, it is believed that the medicinal value and health care efficacy of Polygonatum polygonatum will be more widely recognized and applied, and make greater contributions to the cause of human health.
