Modern research has identified a number of bioactive compounds after a chemical analysis of the calabash tree. Flavonoids like anthraquinone and quercetin can be found in both the leaves and the fruit of the herb. These play an important role in ant-iangiogenic processes, which control the development of the blood vessel network of the body. They can also divert the blood flow away from tumours, which deprives tumours of nutrients and can eventually kill them. Tumours develop from a single cell that multiplies out of control, after many processes of division. This can't happen if the flow of nutrients to the area is stopped.
