How to distinguish and choose good Ganoderma

Precious essences from Ganoderma are used to prevent and treat diseases, but not all fungi have medicinal value, some have only wood properties, even toxic, need to be carefully distinguished.

Ganoderma lucidum (Leyss ex.Fr) Karst has a scientific name. In China and Vietnam, it is also called: chi chi, knitting chi, fairy, lim mushroom, and swiss.

According to the Big Mushroom book in Vietnam by Professor Trinh Tam Kiet, the world's Ganoderma has more than 50 species, 48 ​​in China alone, and about 37 in Vietnam. Lingzhi is distributed in forests with many types of broad-leaved trees, especially Lim woods, so-called Lim mushrooms.

For a long time, lingzhi was recorded as a precious medicinal herb, used in many ancient remedies. The book "The draft of the outline" of Ly Thoi Tran in the Ming Dynasty in 1590 recorded 6 types of Ganoderma: 'green, red, yellow, white, black, purple'; 'eating many times your body is light but not old, living as long as a fairy' . In Vietnam, from more than 200 years ago, Hai Thuong Lan Ong Le Huu Trac (1720-1791) used Ganoderma for healing as well as strengthening health.

According to Master Co Thi Thuy Van, expert of edible mushroom - medicinal mushroom belonging to the Center for Plant Biotechnology (TTCNSHTV) - The Institute of Agricultural Genetics, currently in our country, the growing of Ganoderma is very strong. . Scientists have collected and isolated fungi of natural origin in Vietnam.

In 2000, from the source of natural mushrooms of Ganoderma in the protection forest, special-use forests belonging to 3 communes of Dong Son, Ky Thuong and Hoa Binh in Hoanh Bo, Quang Ninh districts, expert Nguyen Thi Son and TTCNSHTV's authors. The study selected to create successfully the Ganoderma mushroom DT, recognized as a national breed in 2005.

According to expert Van, Vietnam has built and completed the technological process of growing lingzhi mushroom by transplanting seed on the price of sawdust, put into nursery houses to care and collect. The time from mushroom to harvest is about 70 days, yield up to 30kg of dried mushrooms from every ton of material.

Ganoderma is effective in regulating blood pressure and cardiovascular disease; enhance immunity; increased blood supply of oxygen; sedation, treatment of neurasthenia, relieve cough, cure nephritis, asthma; Excretion of toxins in the body, beautiful skin, removal of strange pigments on the skin, and helps promote the formation of proteins, DNA, RNA, prolonging the life.

In order to prevent diseases, we can boil water for Ganoderma with a quantity of 10-15g Ganoderma / person / day; or soak alcohol with 200g of Linh Chi / 3 liters of wine 45 degrees, soak for at least 20 days, soak the alcohol for longer in delicious. In addition, to treat illness, the patient should pay attention to the dosage and how to coordinate other medications.

Not all spirits will treat disease

In Vietnam or China, people sometimes pick or collect lingzhi trees of large size, more than 1m in natural forest, often called 'thousand years'.

"There are many different strains of Ganoderma, but not all strains have medicinal properties. Linh chi has medicinal properties only when collected at the right age, has not spread spores or is in the stage of spores dispersal. " Master Van said.

"The types of thousand years of spirituality spent many spores dispersing spores, each end when it will be converted into cellulose, very little medicinal properties. There are strains of lingzhi which are wood-breaking species, not calculated. medicinal herbs, even if grown on the trunk of poisonous plants, the spirit tree itself will absorb the poison, when used can be poisoned. Therefore, people should not arbitrarily use the spiritual products yet. through testing ".

The life of Vietnamese people is increasing. Consumers tend to look for the products of Chinese Ganoderma, Korea, Japan, but "no one knows when they come to Vietnam, these products have been extracted or not. If you want to know , it is necessary to bring the product to inspection " , expert Van recommends.

The strains of Vietnamese Ganoderma that are sold on the market must be certified by the Ministry of Agriculture and Rural Development as Seed Certification and Technology Process Certification. Before being recognized, Ganoderma must be cultivated for testing. Linh chi will be tested at the Central Institute of Medicine, as well as put into clinical trials on people in traditional medicine hospitals.

Test shows that Vietnam's DT products have the active pharmaceutical value equivalent to products of Korea and Japan. Therefore, consumers should buy Vietnam 's Ganoderma products, domesticated lingzhi varieties and prove medicinal properties, and recognize them as national products to protect their health and relatives.
