About this species
Kigelia africana is an African tree, easily recognised due to the large sausage-shaped fruits hanging from its branches. The generic name Kigelia comes from the Mozambican name for sausage tree, 'kigeli-keia'. Sausage trees are sacred to many communities and are often protected when other forest trees are cut down. In Kenya, the Luo and Luhya people bury a fruit to symbolise the body of a lost person believed to be dead.
The flowers only open at night and are pollinated by bats and hawk-moths. They are dark red, which is unusual for a bat-pollinated species (bats are normally attracted to white flowers), but the strong unpleasant smell of the flowers is thought to attract the bats instead.
Every part of the tree is used in herbal medicines (eg for digestive and respiratory disorders, and to treat infections and wounds). The sausage tree is used in a variety of commercial applications to treat skin complaints. Research into its anti-bacterial, anti-fungal and anti-tumour activity is ongoing.
