سوال و جواب هایی در ارتباط با قارچ ریشی یا گانودرما

1. What is reishi?
   Reishi is a type of mushroom that grows on live trees. Scientists may call it either Ganoderma lucidum or Ganoderma sinense. In traditional Chinese medicine, this group of mushrooms is known as Ling Zhi. In Japan, they are known as Reishi. In China, G. lucidum is known as Chizhi and G. sinense is known as Zizhi.
   There are many other types of Ganoderma mushrooms and it is hard to tell the medicinal mushrooms from the other types.
   Reishi has been used as medicine for a very long time in East Asia. It was thought to prolong life, prevent aging, and increase energy. In China, it is being used to strengthen the immune system of cancer patients who receive chemotherapy or radiation therapy.
2. How is reishi given or taken?
   Reishi is usually dried and taken as an extract in the form of a liquid, capsule, or powder.
3. Have any laboratory or animal studies been conducted using reishi?
   In laboratory studies, tumor cells are used to test a new substance and find out if it is likely to have any anticancer effects. In animal studies, tests are done to see if a drug, procedure, or treatment is safe and effective in animals. Laboratory and animal studies are done before a substance is tested in people.
   Laboratory and animal studies have tested the effects of the active ingredients in reishi mushrooms, triterpenoids and polysaccharides, on tumors, including lung cancer. See the Laboratory/Animal/Preclinical Studies section of the health professional version of Medicinal Mushrooms for information on laboratory and animal studies done using reishi.
4. Have any studies of reishi mushrooms been done in people?
   Studies using products made from reishi have been done in China and Japan.
   Lung cancer
   Studies suggest that the use of products made from reishi as adjuvant therapy may help strengthen the immune system in patients with lung cancer.
   Studies in patients with lung cancer include the following:

   • In an open-label trial done in China, 36 patients with advanced lung cancer were given an over-the-counter product made from reishi called Ganopoly. The patients were being treated with chemotherapy or radiation therapy, along with other complementary therapies. Some patients had marked changes in the immune responses being studied, such as lymphocyte count and natural killer cell activity, and some patients had no change in immune response. A similar study of Ganopoly in 47 patients with colorectal cancer showed the same results.
   • In China, a study was done with 12 lung cancer patients. Their blood was tested to see if taking a product made from reishi could help improve immune response. The study found that the polysaccharides in reishi mushrooms may help cancer-fighting immune cells, called lymphocytes, stay active.
   Colorectal cancer
   The following study looked at reishi for the prevention of colorectal cancer:

   • In Japan, 225 patients with benign colorectal tumors were studied. For 12 months, 123 of the patients were given an extract of the mushroom G. lucidum mycelia (MAK), while 102 patients did not receive treatment with MAK. At 12 months, a follow-up colonoscopy was done on all the patients. The number and the size of the tumors decreased in the group that received MAK, but not in the group that did not receive MAK. The researchers suggest that MAK may help stop benign colorectal tumors from forming.
