In our lives, in fact, there are many animals and plants named that sound slightly strange, such as Wang Bu Liuxing, ten merits, etc., at first glance, there will always be a feeling of not knowing what to do. In addition, in the world of traditional Chinese medicine, there is also a type of plant, its name is very immortal, it is "immortal surplus food", and the reason for this name, mainly because people at that time believed that this plant belongs to the class of sesame grass, "the essence of the soil", and at the same time has the effect of chewing and satiety, hence the name.
The ancients believed that this plant belonged to the category of sesame grass, which is what we often call fairy grass Ganoderma lucidum, but such a miracle medicine was not classified as one of the "nine immortal grasses" during the Tang Dynasty, but even so, its popularity was not inferior to the nine immortal grasses.
As we all know, the ancients have always been obsessed with ascending to immortals, especially many emperors, in the pursuit of immortality, they have tried all kinds of methods, and there is such a medicinal herb is regarded as "immortal surplus food", it is the plant - yellow essence.
To be precise, Huangjing is not a sesame plant, but a lily plant, its rhizome is cylindrical, but there are nodules, and the nodule site is swollen, according to its shape, there are many different species.
And Huangjing can be called "immortal surplus food", this is not without reason, in the eyes of doctors, it is a medicinal material with high medicinal value, with a very wide range of use prospects.
Not only did the doctor Tao Hongjing praise Huang Jing, but the famous doctor Li Shizhen of the Ming Dynasty also valued Huang Jing, and even called it "the king of qi and blood double supplements", in the Materia Medica's magnum opus "Compendium of Materia Medica", it was evaluated as follows: "Huang Jing is a medicine for taking food", and in the "Famous Doctors", Huang Jing is also at the head of the grass.
Traditional Chinese medicine believes that yellow essence is flat and sweet, classified into the spleen meridian, lung meridian and kidney meridian, and has the effect of nourishing qi and yin, strengthening the spleen, moisturizing the lungs and benefiting the kidneys. It is a Yin tonic drug classified under deficiency medicine, mainly used for spleen and stomach qi yin deficiency, lung yin deficiency, kidney sperm deficiency and other diseases.
Although yellow essence is not classified as "nine immortal grasses", but in the Taoist classic "Daozang", it is also recorded that eating yellow essence can enrich muscles and make the body stronger, and the ancients said "long service without hunger, prolong life", although there is a certain exaggeration, but from the effect of yellow essence, such a description seems to be reasonable.
In many later medical works, Huangjing has been elaborated in great detail, and it has also been widely used in traditional Chinese medicine. Although yam and yellow essence also have the effect of qi and yin, the ability of yellow essence to nourish the kidneys is much stronger than that of yam, and yam is better at nourishing the spleen and stomach.
In addition to being a medicinal herb with high medicinal value, yellow essence also has high edible value. The taste of yellow essence is sweet, which can play a certain effect of strengthening the body, especially in the "Rescue Materia Medica" compiled by the Ming Dynasty botanist Zhu Yu (sù), which included yellow essence in the list of ancient "life-saving food" and was one of the famine relief foods.
