Yun Zhi ( Coriolus mushroom) Yun Zhi means Cloud Mushroom in Chinese, its formal botanical name is Coriolus versicolor. The powder is extracted from Yun Zhi Mushroom (Cov-1 strain of Coriolus versicolor). Its active ingredients are PSK and PSP. The extracted polysaccharide called Polysaccharide K (PSK) is also known as Krestin. The PSP is a protein-bound polysaccharide peptides. The main component unit of the polysaccharide moiety is 1,4- and -1,6- glucans with -1,3- and 1,6- linkages. The reference of its usage can be traced in the Chinese Compendium of Materia Medica as far back as the 15th century. So far, There has been a number of scientific studies conducted and published by researchers and medical professionals in Asia on the effectiveness and safety of Yun Zhi. Many experimental studies and clinical investigations of PSK and PSP in relation to their antitumor effect and especially for their potential use in cancer immunotherapy have been reported. These studies include the clinical trial on 485 cases of cancer patients who have used Yun Zhi Extract for the treatment of cancer alone or in combination with chemotherapy and radiotherapy. The results of these studies have consistently shown increased survival rates and improved quality of life without toxic side effects. The total effective rate is 82.96%. Animal studies investigating the efficacy of Coriolus versicolor indicate it has marked immune system-enhancing activity and a broad antineoplastic scope. It prolongs the survival time of irradiated (cancer-induced) mice by stimulating phagocytic activity of macrophages and improving the functions of the reticuloendothelial system. It also has antiviral and antibacterial effects, which includes anti-hepatitis B and migratory hepatitis virus. Coriolus versicolor has been used for centuries in Traditional Chinese Medicine. Modern clinical research has focused on using the water extracts of this mushroom to stimulate and strengthen the immune health of people with cancer. The immune-stimulating compounds found in Yun Zhi (Coriolus versicolor), known as PSK in Japan, has generated sales of several hundred million dollars a year, making them the world��s top-selling natural products used by cancer patients. In Japan, where PSK is dispensed as an authorized drug, it is sold for approximately $1,000 per month at a dosage of 3 grams per day. As a US food product, this same monthly supply can be sold for about $149 retail. We are offering a much better price with a highly concentrated product . 100 gm 50:1 (35 % Polysaccharides) from raw wild grown powder extract.

本品別名白山雲芝、染色本雲芝、瓦菇等，係多孔菌科植物雲芝 Coriolusvcrsicolo的菌體。中國各地均有分布。味甘，性微寒。傳統功用為健脾強身，調節免疫。在1970年代，研究人員從雲芝的菌絲中分離出高分子的多醣體。這雲芝多醣體K(PSK)也被稱為Krestin，包含有具有主鏈β(1-4)的葡萄糖聚合物和分鏈3和6的葡萄糖的β葡聚醣 (beta-glucan)，雲芝多醣PSK已知具有抗微生物、抗濾過性病原體和抗腫瘤的特性。

雲芝是現今世上最暢銷的天然治癌寶物。在日本，雲芝一年就有數億元的銷售額，也有超過80篇的人體臨床研究，它是被最廣泛研究的菇類之一。事實上，早在1965年，就有許多文獻報告指出，雲芝可以有效的對抗胃癌。

上海醫科大學腫瘤醫院統計的一百個病例，也發現服用雲芝的組別，五年內的死亡率僅為兩成八，比沒有服用雲芝的對照組別，死亡率減少三成。根據上述研究，專家相信，雲芝能減低癌症患者的死亡率，並且能減輕患者在化療期間出現的痛楚。對白血病、淋巴瘤、胃癌、乳腺癌、子宮頸癌、甲狀腺腫瘤等多種種瘤有免疫機能低下者有幫助。與放、化療同用可提高療效。現代研究：本品含有多糖類、脂肪、蛋白質等成分。雲芝的蛋白多糖體(PS-K)被証實是通過增強腫瘤患者特異性免疫功能而發揮其抗癌作用。寶生公司雲芝產品至少含20%多醣體。100粒裝編號BE80
