Abstract: Ganoderma contains 10 times more natural organometallic compound germanium than ginseng. The organometallic compound germanium helps to identify cancer cells, encourages the macrophage to envelop tumor cells, and also stimulates the production of interferon, improves the function of the immune system and inhibits the development of cancer cells. Modern laboratory and clinical studies have revealed anti-inflammatory, antiviral, antimicrobial, antiallergic and antitumor properties. Keywords: Ganoderma, organometallic compounds of germanium, ginseng, cancer cells, interferon, immune systems, laboratory and clinical studies Introduction Many people might wish to live forever, without knowing illness and old age. The Daoists believed that achieving this was possible by following specific rules and consuming certain magical herbs. Among the herbs was also the wood mushroom reishi. In Japan, it is called reishi, while modern systematics refer to it as Ganoderma lucidum – glossy ganoderma. The genus Ganoderma comprises over 250 species, but when referring to Ganoderma, we specifically mean the glossy variety. Ganoderma parasitizes on dying trees, both deciduous and coniferous, on fallen trunks covered with soil. It appears that the mushroom is growing directly from the ground. It has long legs and a bright hat. It is not surprising that such a beautiful mushroom caught people's attention. According to legend, the mythical immortal Emperor,

Divine Farmer Shennong, first experienced the effects of tea. In the Chinese book "Shen Nong Ben Cao Jing" (Shen Nong's Classic of Roots and Herbs) written 100 years before our era, mushrooms were classified as highly beneficial and non-toxic[1-3]. The book "Bao Pu Zi" (Magical Medicine), published in the 3rd century, NUKUS · 2026

describes different ways to color lingzhi mushrooms. It can be red as coral, white as suet, black as lacquer, green as a peacock (more likely, blue-green), yellow as gold, and yet glistens like ice. Colorful mushrooms are distinguished by their properties. Red hellebore tastes bitter and is used to treat chest congestion and improve memory. The black hawthorn is slightly salty and assists with kidney X A L Q A R O I L M I Y- A M A L I Y K O N F E R E N S I YA

problems. Blue sour cinchona improves vision and liver function. Yellow sweet hawthorn treats heart, spleen, and stomach diseases, while white spicy hawthorn is beneficial for cough and lung diseases. The sixth "zhi" added to these five – sweet purple Cizhi, which heals deafness and arthritis[4-11]. When modern Western specialists express doubt about the effectiveness and safety of folk remedies, supporters of traditional Chinese medicine proudly respond that their preparations do not need clinical testing as they have been tested by centuries of practice. However, the beliefs that existed thousands of years ago still require further clarification. In the 20th century, Chinese scholars revised the concept of the "six zhij" according to modern classification and concluded that not « O ‘ Z B E K I S T O N O L I M A AY O L L A R I N I N G M A M L A K AT T A R A Q Q I Y O T I G A Q O ‘ S H AY O T G A N H I S S A S I »

all "zhij" actually belong to the genus Ganoderma. The blue larch bolete could be the multicolored mushroom Coriolus versicolor. Yellow lichen – presumably Laetiporus sulphureus, and white lichen – extremely bitter Fomitopsis officinalis. Therefore, we cannot confidently say which mushrooms are mentioned in the "Bao Pu Zi" and other Chinese medical treatises.

Fruit bodies and mycelium of Ganoderma lucidum contain carbohydrates (reducing sugars and polysaccharides), amino acids, peptides, proteins, triterpenes including steroids, lipids, alkaloids, glycosides, volatile essential oils, vitamins, trace elements such as magnesium, manganese, molybdenum, calcium, zinc, potassium, sodium, iron, copper, sulfur, germanium. Germanium, contained in high concentrations in the fruit bodies of Ganoderma lucidum, is part of the organic compound carboxyethyl germanium sesquioxide (The compound was first synthesized in 1967 at the Asai Research Institute in Japan. It is a water-soluble organogermane compound used as a raw material in food additives). The most important biologically active compounds isolated from this mushroom are polysaccharides and triterpenes. Almost all the preventive and therapeutic effects known in the glazed tinder fungus are found in these two groups of compounds.

The spore-bearing structures of Ganoderma lucidum contain carbohydrates (simple and complex sugars), amino acids, a small amount of proteins and inorganic ions, triterpenoids, fats, alkaloids, glycosides, coumarin glycosides, essential oils, riboflavin, and ascorbic acid. Inorganic ions include mainly magnesium, calcium, zinc, manganese, iron, copper, and organic germanium. Disputes contain choline, betaine, tetracosanoic, stearic, palmitic, ergosterolic, nonadecanoic, and behenic acids, tetracosane, higher alkaloids, ergosterol, and beta-sitosterol. Pyrophosphoric acid is isolated from the lipids of Ganoderma lucidum. Terpenoids, derivatives of triterpenes, increase stress resistance or, in other words, "restore harmony", which is the main definition for adaptogens. Triterpenes affect nonspecific immunity, including the complementary activity and function of NUKUS · 2026

macrophages. They improve liver function, and also have many valuable pharmacological properties, such as lowering blood lipids, normalizing blood pressure, calming effect on the nervous system, relieving inflammation and pain, promote detoxification of the body, and have an antioxidant effect. Nucleoside analogues in Lingzhi mushroom spores include adenine, adenosine and uracil X A L Q A R O I L M I Y- A M A L I Y K O N F E R E N S I YA

RNA, which have an active physiological effect. Adenosine perfectly prevents the formation of blood clots. Method 1.
