The herb Mistletoe was popularized in treatment for cancers almost twenty years ago. The same can be written about laetrile, B17. Mistletoe is true immunotherapy - meaning it has many actions on your immune system. It has been shown to strongly affect natural killer cells which promote cancer cell death. It also has been shown to decrease recurrence.
There are more than 4,500 scientific published papers on the effectiveness of this herb in killing cancers. It has been shown to increase the quality of life and stimulate the immune system. It has been shown to alleviate the side effects of conventional chemotherapy and radiation.
Mistletoe has been shown not to interfere with conventional chemotherapy, but increases the effectiveness of conventional chemotherapy. A meta analysis of more than 3,000 patients treated with mistletoe also had a positive effect on their survival. The study concluded that the destructive effects of cancer on the immune syste can be counteracted by mistletoe.
