Tai sui is edible, also known as meat ganoderma lucidum, which is the elixir of life that Qin Shihuang struggled to find in ancient Chinese legends. Li Shizhen did record the meat ganoderma lucidum in Compendium of Materia Medica, and put it in the category of "Zhi" in the department of "vegetables". Eating it as medicine is regarded as "the superior product of this meridian", which has the effect of "keeping fit for a long time and prolonging life".

According to Shennong's Classic of Materia Medica, "Ganoderma lucidum is non-toxic, nourishing, benefiting essence and qi, increasing wisdom, curing the knot in the chest and strengthening the body for a long time." Shan Hai Jing called it "seeing meat", "gathering meat", "letting the old age" and "sealing", which was a delicious health care for ancient emperors.

Extended data:

Modern science has found that Ganoderma lucidum is a large myxomycete complex between protozoa and fungi. Its structure is not composed of a single cell, but a polymer composed of bacteria, myxomycetes and fungi.

Studies have shown that Ganoderma lucidum feeds on microorganisms such as bacteria, yeast and mold spores. Take cellulose, chitosan, chitin, etc. As a nutrient, it is rich in protein, nucleic acid, candida and Geotrichum candidum. Its cells contain photosynthetic pigments. According to the genealogical analysis of the origin and evolution of life, it should be located between bacteria (algae) plants and protozoa.
