Ganoderma lucidum is a species of new food resource, which is the whole herb of Zizhi or Chihze of the family Polyporaceae, with a sweet taste and flat nature, which can nourish the five organs, strengthen the muscles and bones, and cure deficiency. The folklore is mysterious, for example, in “The Legend of the White Snake”, it is described that Lingzhi has the effect of reviving the dead and the White Lady steals the immortal herb to save Xu Xian’s life. Nowadays, Lingzhi is mostly cultivated for medicinal use. According to the Ben Jing, it “benefits the vital energy and strengthens the muscles and bones”. In Chinese medicine, it is emphasized that Lingzhi has strong effects such as tonifying qi and nourishing blood, strengthening the brain and kidney, relieving cough and calming the mind. It is used for deficiency and cough, deficiency of vital energy, insomnia and palpitation. It is believed that Lingzhi contains polysaccharides, organic acids, ergosterol, various enzymes and alkaloids, and animal experiments have proved that it has many effects such as enhancing physical strength, prolonging life span, enhancing myocardial contractility, relieving cough and phlegm, and inhibiting bacteria. Clinical use of Ganoderma lucidum is considered to have sedative, tranquilizing, beneficial to lungs and asthma, anti-arrhythmic and hepatoprotective effects, and has certain strong effects. The inhibitory effect of Ganoderma lucidum on tumors has been studied more frequently, and the polysaccharide of Ganoderma lucidum substrates has an inhibitory effect on a variety of transplanted mouse tumors. It can also reduce the size of tumors in mice with certain carcinogen-induced esophageal cancer. Ganoderma lucidum is rich in organic germanium, with a content of about 800-2000 ppm per 100 grams, which is several times higher than ginseng. Organic germanium is effective in tumor prevention and is also a good immune booster. Reishi can enhance the synthesis of protein and nucleic acid in bone marrow cells, protect the function of bone marrow, reduce the damage of chemotherapy drugs and rays on bone marrow, thus can improve the cellular immune function and the number of white blood cells in peripheral blood. Ganoderma lucidum can correct the symptoms of deficiency of vital energy and qi and blood in patients with mid- to late-stage tumors, thus enhancing physical strength and improving quality of life, and achieving the effect of supporting the righteous and dispelling the evil. However, both Ganoderma lucidum and Ganoderma lucidum spore powder are auxiliary products for tumor treatment, and tumor treatment still mainly relies on regular treatment by specialized means. At present, there are many Ganoderma preparations used in the society, such as Ganoderma syrup, Ganoderma mycelium tablets, Ganoderma injection and Ganoderma polysaccharide injection, and spore powder. Now we can also use solid culture of Ganoderma lucidum mycelium, which can further research new dosage form. In recent years, the technology of artificial cultivation of Ganoderma lucidum is mature and the yield is very high, so there is no mystery anymore, and it is easy to take Ganoderma lucidum into medicine and make medicinal meals. To take Lingzhi into medicine, generally break it into small pieces, wrap it in gauze, soak it in cold water for 2~3 hours, and filter the soaked water with Lingzhi into the meal.
