Papayas are one of the most common hosts for fruit flies like A. suspensa, which lay their eggs in overripe or spoiled papayas. The larvae of these flies then consume the fruit to gain nutrients until they can proceed into the pupal stage. This parasitism has led to extensive economic costs for nations in Central America.

Effect of a quality-controlled fermented nutraceutical on skin aging markers: An antioxidant-control, double-blind study. Exp. Ther. Med. 2016, 11, 909–916. [ Google Scholar] [ CrossRef] [ PubMed][ Green Version] Papain is available in several forms, including as capsules, tablets, powders, chewable gummies, creams and ointments. Papain is also an antioxidant and anti-inflammatory. As such, it can neutralize excess free radicals that can build up and contribute to a number of chronic diseases [ 7, 12, 13, 8, 14]. Snapshot Papaya leaves are usually consumed orally or applied topically for soft, clear, and young-looking skin. Papaya leaves also contain papain, a protein-dissolving enzyme. So, the leaf extract can be used topically as an exfoliant to remove dead skin cells, clear clogged pores, and treat acne.

Vitamins A and C can also help to naturally brighten your skin’s appearance and promote a natural glow.

What’s more, your body absorbs these beneficial antioxidants better from papayas than other fruits and vegetables ( 3). There are many papain preparations. The enzyme is commonly taken in supplement form or applied topically to reduce inflammation, promote wound healing, aid digestion and fight pain.

Because of its rich amounts of vitamins A, papaya fruit extract can be used to help protect your skin from UV damage by reducing your skin’s sensitivity to the sun. It’s believed that people who are allergic to kiwi and fig may also be allergic to papain. People who experience allergy symptoms after being exposed to these fruits should definitely be cautious when using papain topically or internally.

It’s is not considered safe to use papain supplements during pregnancy or while nursing. Sources and Dosage Recommendations Carica papaya was the first transgenic fruit tree to have its genome sequenced. [30] In response to the papaya ringspot virus outbreak in Hawaii in 1998, genetically altered papaya were approved and brought to market (including 'SunUp' and 'Rainbow' varieties.) Varieties resistant to PRV have some DNA of this virus incorporated into the plant's DNA. [31] [32] As of 2010, 80% of Hawaiian papaya plants were genetically modified. The modifications were made by University of Hawaii scientists, who made the modified seeds available to farmers without charge. [33] [34]
