''
inflorescence '' Several species are used in
African or
Indian herbal medicine. Several species of this genus in
Madagascar known collectively as
voantamenaka or
voatamenaka (from
voa 'fruit' and
menaka 'oil') are used in traditional Malagasy medicine as
deworming remedies. The class of chemical compounds known as
combretastatins were first isolated from
South African bushwillow (
Combretum afrum), from which they get their name. One synthetic
derivative,
fosbretabulin disodium (combretastatin A4 phosphate), underwent preliminary study for the treatment of
anaplastic thyroid cancer, but it was not effective enough to progress to more advanced trials.
C. molle is also recorded to contain
antioxidants such as
punicalagin, which is also found in
pomegranates (
Punica granatum), a somewhat related plant. The
botanist George Don studied this genus extensively. The
Luvuvhu River in southern Africa was named after the river's bushwillows (
C. erythrophyllum), locally known as
muvuvhu. ==Species==
