After I posted the last message I looked on line again to find information on maitake mushroom extract...I was on the American Cancer Society web site and this is what I found about maitake D-fraction extract... very convincing..I
" What is the evidence?
D-fraction contains a polysaccharide called beta-glucan (sometimes called beta-glycan) that is found in several mushrooms, yeasts, and other foods. A polysaccharide is a large and complex molecule made up of smaller sugar molecules (similar to the lentinan in shiitake mushrooms; see Shiitake Mushroom). The beta-glucan polysaccharide is believed to stimulate the immune system and activate certain cells and proteins that attack cancer, including macrophages, T-cells, and natural killer cells (types of white blood cells) and interleukin-1 and -2. In lab studies, it appears to slow the growth of cancer in some cell cultures and in mice.
Most of the research on maitake D-fraction has been done in Japan using an injectable form of the extract. A 1997 study published in the Annals of the New York Academy of Science found that maitake D-fraction extract was able to enhance the immune system and inhibit the spread of tumors in mice that had been implanted with breast cancer. In a 1995 report published in the same journal, researchers concluded that maitake D-fraction extract was able to activate the immune response in mice injected with liver cancer cells to prevent the spread of tumors to the liver, and prevent the development of cancer in normal cells.
Animal and laboratory studies may show a certain compound holds promise as a beneficial treatment, but further studies are necessary to determine if the results apply to humans. In 2002, a group of Japanese people with different types of cancer were given D-fraction and maitake powder in addition to standard cancer treatment. Although the researchers thought some patients fared better, there was no comparison group. It is impossible to say for certain if there was any effect, or whether it was from their cancer treatment or from the extract. Because of the study design, no conclusions can be drawn. More scientifically designed studies are needed to determine maitake’s potential usefulness in preventing or treating cancer.
The National Cancer Institute is sponsoring a very early (Phase I) study at Memorial Sloan Kettering Cancer Center to learn if beta glucan can increase the effectiveness of rituximab (a drug used for cancer treatment) by making cancer cells more sensitive to it. This clinical trial is studying the side effects and best dose of beta-glucan when given together with rituximab. It will look at young patients with relapsed or progressive lymphoma, leukemia, or similar disorder.
In another clinical trial, beta-glucan is being tested along with other drugs to learn if they increase the effectiveness of another monoclonal antibody (3F8). Combining different types of biological therapy may kill more tumor cells. This is a small open label trial in patients with neuroblastoma that has not responded to treatment. A trial of maitake extract as treatment for breast cancer is also in progress. " American Cancer Society
Maitake is outline in great detail in the book by Dr. Michael Murray
Again...good luck....
