The search for cures to treat common diseases is not new, nor is it unusual to find the cures for such diseases in tree bark. Aspirin for headaches and quinine for the treatment of malaria are both examples of modern medicines which have been derived from tree bark. But the latest additions to this list may be the most significant yet, according to the findings of research into the medicinal benefits of the bark of the African Bush Willow. At an international conference, Dr Scott Remick of the USA claimed that combretastin, a product of this bark, has proved up to 85% effective in combating cancer, and may, in combination with chemotherapy, finally provide a way to destroy many types of tumour.

The African Bush Willow, which grows in South Africa, has been recognised as a medicinal plant by local tribespeople for many years. In the past, its roots were used as purgatives and its gum was used to treat sores and ulcers. Common along river banks in southern Africa, this plant has proved both hardy and prolific, It is one of the worlds fastest-growing trees and can grow one metre in height annually to a maximum of fourteen metres. To sustain this level of growth normally requires warmth, rich soil and abundant water. but even when these are in short supply, the African Bush Willow can survive. It is resistant to severe drought and even sustained periods of frost, and temperatures well below zero do not damage the tree.
