The Propolis protects from the occurrence of stomach cancer, colon cancer, liver cancer, kidney cancer and skin cancer. During chemo therapies it protects kidneys and heart from acute damage with cytostatics (the cisplatin). The Native propolis has strong antioxidant effect. The “Ruder Boskovic” showed that it explicitly amplifies the gene whose lack leads to appearance of reproductive organs cancer, lungs cancer and lymphatic system cancer. In this case the Propolis is very helpful to any one. http://hedera.hr/propolis-research/native-propo...
