Parts used and preparation
Leaves and fruit.
Indigestion: Warm the leaves in open fire. Apply to stomach while still warm; use abdominal binder. Renew every 2 hours. Also used for babies and children.

• Phytochemicals: Study isolated two annonaceous acetogenins from the seeds of Anona reticulata: squamone and isoannonareticin.
• Anthelmintic: (1) Study showed the ethanol extract of Annona reticulata exhibited anthelmintic activity, taking less time to cause paralysis of the earthworms, Pherentima posthuma. Activity was attributed to a compound present in fraction of the ethanol extract. (2) Extracts from the bark of A reticulata showed potent anthelmintic activity.
• Annonacin / Cytotoxicity / Anti-Cancer: Study of annonacin isolated from the seeds of A reticulata showed it caused significant cell death in various cancer lines and suggests a potentially promising anticancer compound.
• Antioxidant Study: In a study of antioxidant potential of leaves of three diffferent species of Annona, A reticulata showed better activity in quenching DPPH and superoxide radical than A squamosa and A muricata.
