Reishi
Evidence
A 2016 Cochrane systematic review of use of reishi for treatment of cancer included 5 randomized, controlled-trials (373 subjects). The analysis found that patients who were given reishi in combination with their chemotherapy/radiation therapy had greater tumor regression with treatment than those treated with chemotherapy/radiation therapy alone, and quality of life improved. Treatment with reishi alone did not show a benefit. There was no evidence of survival benefit ( Reference ).
