Hydrangea, also known as hydrangea mushroom, Latin scientific name for Sparassis crispa , is a non-pleated foramen order, Hydrangeaceae, Hydrangea genus. The fruiting body is medium to large, fleshy, and consists of a stout stalk with many branches, the ends of which form numerous zigzag flaps resembling giant hydrangeas.
It is mainly distributed in the domestic forest areas of Jilin Province, Heilongjiang Province, Yunnan Province and other places, and abroad in Japan, Korea, the United States, Canada, Australia, but the resource reserves are relatively rare. It is very rare, known as the "king of all mushrooms", and is a very rare and valuable medicinal and food mushroom in the world. It is a rare and valuable medicinal and food mushroom in the world. It is rarely found in the wild, and is occasionally found in spruce and fir forests in the Changbai Mountains in the northeast of China, and in the mountains of Yunnan, Guizhou, and Sichuan.
Because of its high immune-activating ability, it is known as the "Magic Mushroom of Dreams" in Japan. While ordinary mushrooms grow in the shade, hydrangea mushrooms require more than 10h of irradiation per day, making them the only "sunshine mushrooms" in the world. It is the only "sunshine mushroom" in the world. It is extremely popular and expensive in Europe, America and Japan.
Hydrangea also contains a large amount of beta glucan, antioxidant substances, vitamin C, vitamin E, as the effective ingredient of beauty products, to remove melanin precipitation and other skin problems have a good effect.
Coccidioides contains a lot of beta glucan The biggest feature of hydrangea is that it contains a lot of beta glucan. According to the analysis of the Japanese Food Analysis Center, every 100 g of hydrangea contains up to 43.6 g of β-glucan, which is 3 to 4 times higher than Ganoderma lucidum and Agaricus mushrooms. It can be said that the β-glucan contained in hydrangea is the highest among mushrooms. Glucan is a polysaccharide polymerized from glucose monomer, divided into α-type and β-type. α-type glucan, such as starch, is the main source of energy for the body and does not have biological activity. β-type glucan is a biologically active substance, which has been confirmed by medical research to have various functions such as immune regulation, anti-tumor, anti-inflammatory, anti-viral, antioxidant, anti-radiation, hypoglycemic, lipid-lowering, liver-protecting and etc. Most of them have the function of anti-tumor, anti-oxidant, anti-radiation, blood sugar, lipid-lowering, and liver-protecting. It has also been found that most polysaccharides with anti-tumor activity are β(1-3)D glucans with β(1-6) glycosidic bond branches. It has been demonstrated that β(1-3)D glucans from fungi usually have tumor-suppressive effects. More than 70% of the glucan in hydrangea is β(1-3)D glucan, which has good anti-tumor, immunomodulation and improve hematopoietic function.
Hydrangea contains a large number of vitamins and minerals Hydrangea contains vitamin C, vitamin E, its vitamin E content ranks in the forefront of fungal food, these vitamins have antioxidant effects. Hydrangea also contains ergosterol, in sunlight and ultraviolet irradiation can be transformed into vitamin D, can promote calcium and phosphorus absorption, is conducive to the formation of bones, prevention of rickets in children, adult osteomalacia and osteochondrosis. Hydrangea contains a fairly high element of potassium, while the sodium content is low, this high potassium and low sodium food has a diuretic effect, is very beneficial to patients with high blood pressure.
Hydrangea contains a large number of antioxidant substances Free radicals in the body will cause oxidative damage to biological cells and lead to aging of the body, and destroy the body's resistance, defense, leading to cancer and cardiovascular disease and other chronic diseases. Nowadays, the antioxidant ability of natural food has been generally valued by people, among which, superoxide dismutase (SOD) can effectively remove free radicals in the body, preventing the damage of reactive oxygen species to the organism, antioxidant and anti-aging effects. It has been determined that the content of superoxide dismutase in hydrangea ranks first among all kinds of edible mushrooms.
