Hibiscus-derived gossypin fights melanoma

The end of March and the beginning of April brought the discovery (1) of Texas scientists to light. The researchers tested a little known substance – gossypin – for its action against skin cancer cells. This naturally-occurring flavone was found to inhibit in vitro human melanoma proliferation. Scientists have also observed a unique mechanism that may be responsible for this effect. Furthermore, gossypin therapy, carried out on mice model, reduced the size of melanoma tumors and increased the survival rates. And this is not the only secret property that this flower-derived flavone has. Read full text »
