Papaya

Papaya fruit from the Carica papaya plant has been shown to decrease gastric acidity, gastric acid output, gastric pepsin secretion, ulcer index and gastric secretion in a research study conducted on albino rats in 2015.

Healing remedies in Belize have reported that sliced fruit or crushed papaya seeds applied to wounds, cuts, and topical infections assisted with healing.

Antibacterial
In laboratory tests, extracts from skin, flesh, and seeds of both ripe and unripe papaya showed in vitro antibacterial activity against several microorganisms, including Bacillus cereus, B. subtilis, Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi, Shigella flexneri, and Staphylococcus aureus.

Animal-based Research
A study revealed the antiulcer potential of aqueous and methanolic extracts of unripe papaya fruit in experimental rat models. The extracts reduced the ulcer index; the methanolic extract demonstrated better protection against indomethacin-induced ulcers, the ethanol extract against ethanol-induced gastric ulcers.

Various studies in animals confirm the effectiveness of C. papaya seeds as an anthelmintic effective against nematodes found in animals. C. papaya has documented activity against protozoa in addition to intestinal parasites in animal models.
