Properties and uses

The fruit are considered toxic, and force-feeding of either ripe or unripe fruit has led to deaths in cattle. Free-ranging cattle apparently avoid feeding on the fruit. The highest concentration of alkaloids (4.4%) is found in the seeds. Nevertheless a fruit decoction, fruit sap, or sap of roasted fruit, has been recorded as traditional remedies in Africa.
