Properties and constituents
• Phytochemical studies have yielded sterols, steroidal sapogenins, steroidal alkaloids and alkaloidal amines.
• Hecogenin (IV), a saponin, is a source of cortisone.
• Study has isolated three new steroidal saponins: dongnosides C, D and E from the dried fermented residues of leaf juices.
• Barbourgenin is a steroidal sapogenin from the leaves.
No reported folkloric use in the Philippines.
In West Africa, lightly heated pounded roots used for intercostal pain; also used for nephralgia.
In Kenya, fibers used as bandage.
Used to treat high blood pressure; stomach and intestinal infections.

• Biologic Activities / Intestianal / Uterine Muscle Stimulant: Pharmacologic study showed that the juice obtained from A sisalana leaves stimulate intestinal and uterine musculature, lowers blood pressure, and produces abortion in pregnant animals.
• Immuno-Modulatory / Flavones / Homoisoflavonoids: Study isolated three known flavones and seven homoisoflavonones from the methanolic extract of A sisalana. Three compounds significantly inhibited the production of IL-2 and IFN-g in activiated PBMC in a concentration-dependent manner.
• Antifertility Effects: Dinordin and anordin from the steroids of A sisalana have been used for antiferlity effects.
• Hecogenin (IV): Hecogenin, a saponin from A sisalana has been used in the manufacture of cortisone.
• Antibacterial: Study of crude methanolic extract has shown antibacterial activity against Staphylococcus aureus and Bacillus cereus.
• Antifungal: Study of hydroalcoholic extract obtained from leaves and sisal waste showed significant inhibition of Candida albicans.
