Will Mushrooms Increase Cancer Survival?

Wednesday, September 19th, 2012

A new study published in an open-access article in the journal Evidence-Based Complementary and Alternative medicine concluded that dogs with hemangiosarcoma treated with a compound derived from the Coriolus versicolor mushroom had the longest survival times ever reported for dogs with the disease providing hope that the compound might one day offer cancer patients a viable alternative treatment to chemotherapy. The mushroom commonly known as Yunzhi mushrooms have been used in traditional Chinese medicine for over 2,000 years and is believed to have immune-boosting properties in the compound known as polysaccharopeptine or PSP. Over the past two decades some studies have suggested PSP may also have tumor fighting effects.

To answer the question of whether of not taking PSP increases the life span the researchers studies 15 dogs diagnosed with hemangiosarcoma that were divided into 3 groups of 5. Each group received a different dose of 25, 50, or 100 mg/kg/da of I’m-Yunity, a formulation of PSP that was tested for consistency and good manufacturing processes. Owners were instructed to give their dogs the compound daily and bring them for follow up visits monthly. Blood tests were taken and ultrasound conducted at the visits to determine the extent the tumors developed or grew and spread in the dog’s bodies. Results showed that tumor progression was reduced and life span lengthen. Researchers were shocked and said “Prior to this, the longest reported median survival time of dogs with hemangiosarcoma of the spleen that underwent no further treatment was 86 days. We had dogs that lived beyond a year with nothing other than this mushroom as treatment.”  Although there was no significant differences in the three dose groups longevity the median survival time was highest ion the group receiving 100 mg. at 199 days. Further trials are planned to confirm and extend these findings.

Prostate Tumors Suppressed by Mushroom Compound

Wednesday, June 1st, 2011


In a new study published in the online journal PLoS ONE the researcher reported that an Asian mushroom used for its medicinal benefits was 100% effective in suppressing prostate tumors in mice. In the study transgenic mice that developed prostate tumors were fed polysaccharopeptide (PSP) a compound extracted from the turkey tail mushroom, for 20 weeks. They reported that no tumors were found in any of the experimental mice fed PSP. However, those not given the PSP developed tumors. They concluded that” findings support that PSP may be a potent preventative agent against prostate cancer.”
