Natural Medical Properties
|The ripe pods and seeds are widely used in both traditional and conventional medicine as a laxative. The root-bark, leaves and flowers also have laxative properties, but to a lesser extent.
In modern medicine, the fruit pulp is sometimes used as a mild laxative in paediatrics.
The fruit pulp and leaves are rich in anthraquinone derivatives (around 2%), and glycosides, which are responsible for the laxative properties.
The fruit pulp is rich in pectins and mucilage.
In-vitro and in-vivo tests have shown that the seed powder has amoebicidal and cysticidal properties against Entamoeba histolytica and that it could cure intestinal amoebiasis of humans. The aqueous fraction of the pods has produced a significant decrease in glycaemia.
An alcohol extract of the leaves has shown antibacterial activity in vivo against Staphylococcus aureus and Pseudomonas aeruginosa, plus accelerated wound healing.
A water extract of the leaves has shown antifungal activity against the human skin pathogens Trichophyton spp., Epidermophyton floccosum and Microsporum ferruginum.
The pods are used as a remedy for malaria, blood poisoning, anthrax, diabetes and dysentery.
The pods contain a sweet, sticky pulp.
The sennoside content of the pods is highest at the mid-stage of fruit maturation, when the pods are pale brown.
