Uses

In New Ireland, leaves are heated over a fire and squeezed when soft. The juice is drunk to soothe throat infections such as laryngitis. In New Britain leaves are used to treat diarrhoea, whereas on the Gazelle Peninsula, leaf juice is drunk with water to treat diarrhoea and dysentery. In the Central Province boiled leaves are used to massage people suffering from fever. In the Southern Highlands the bark is used as a poison. In Fiji, an infusion of leaves and bark is drunk as a treatment for pleurisy. The leaves are squeezed and mixed with water, and drunk to regulate menstruation. A decoction of the leaves is used to treat gastritis and lymphoid swellings. In Central America, fresh leafy branches are externally applied to induce perspiration, apparently for their rubefacient effect. Similarly, heated leaves are applied to cure fevers. Likewise fresh or heated leaves are externally applied to relieve rheumatic pains, inflammations and swellings. In West Africa the water extract of the reddish form is traditionally used for treating skin problems.
