Couple of grams Phellinus linteus daily makes Natural Killer Cells 15 percent more deadly
Because we've already bombarded you with posts on the immuno-regulatory properties of mushrooms we thought... we can do it again, no problem. We stumbled across a Korean human study in which healthy participants were given a couple of grams extract of the medicinal mushroom Phellinus linteus daily. This made their Natural Killer Cells 15 percent more deadly, for cancer cells, that is.
The researchers divided 62 healthy subjects into two equal-sized groups. One group took a placebo for eight weeks; the other took 3.3 g Phellinus linteus extract.
The researchers measured the amount of Natural Killer Cells circulating in the participants' blood, before supplementation started and after it finished. They then put the killer cells in test tubes together with human leukaemia cells, and recorded how many leukaemia cells the Natural Killer Cells destroyed.
Supplementation with Phellinus linteus had no effect on the number of Natural Killer Cells.
But Phellinus linteus did make the Natural Killer Cells more effective. After eight weeks of supplementation the Natural Killer Cells killed 15 percent more leukaemia cells than they did before supplementation started.
Traditional healers in Asia have been using medicinal mushrooms such as Phellinus linteus for centuries as a remedy for cancer, and scientists today are studying the effects of these mushrooms as a complement to chemotherapy and hormone treatments for cancer. We're starting to understand why.
