Traditionally, all parts of papaya, including roots, seeds, flowers, fruit, latex, barks, and leaves, have been used to treat several diseases in various world regions. The fruit, seeds, or leaf extracts of papaya have been shown to possess cytotoxic and anti-proliferative activities and were assessed for estrogen. (Shrefa A. Hadadi, 2018)

The papaya plant is a nutritionally abundant source of vitamins A, B, and C and a fair source of calcium and iron. It contains the enzyme papain. The seed extract of papaya fruit contains benzyl isothiocyanate, which is bactericidal, bacteriostatic, and fungicidal. Papaya possesses excellent antioxidant activity, which plays a role in neutralizing free radical generation and preventing pathogenesis. Latex is one of the essential constituents of papaya, which contains papain, glycyl endopeptidase, chymopapain, and certain, and the abundance of these proteinases varies in different parts of the papaya plant. Papaya leaf contains carbohydrates, vitamins, lipids, and proteins; thus, it can be used as a nutritional agent. (Surya P. Singh, 2020 )

Study indicates that papaya leaf extracts health benefits are impressive. They contain calcium and vitamins A, B, C, D, and E. The antioxidants filled in the leaves fight free radicals that go into the body. Leaf extracts play a vital role in increasing the platelet count. Beyond any question, it offers a cheap and possibly effective treatment for dengue. The flavonoids and other phenols in the papaya leaf have been encouraged to provide beneficial properties. One of the analyses found that the leaves of the papaya plant are rich in uncountable minerals, which might bring equity in mineral deficiency caused by the virus and reinforce the immune cells against it.   (Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021)

According to a study, Vitamin A in papaya can positively affect hair by helping the scalp produce sebum, which nourishes, strengthens, and protects your hair. The compounds in papaya and Lycopene show a potent growth-stimulating activity by increasing hair and protecting against hair loss. (Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021)  Papaya leaves have proteolytic enzymes and phytoconstituents with antimicrobial properties. Rwandan citizens use papaya leaves to treat hair dandruff, wounds, and burns. (Cyuzuzo Callixte, 2020) A study indicated that papaya has antifungal properties. The leading cause of dandruff is a yeast-like fungus called Malassezia. Papaya seeds' antifungal properties can assist in controlling and preventing dandruff.  (Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021)

It is also rich in Antioxidants like Lycopene, which helps defend the visible signs of aging. According to a study, skin damage and wrinkles appear due to excessive free radical activity; antioxidants help fight these free radicals damage and help keep your skin smooth and clean. Another study on rats suggested that papaya helps your skin elasticity, which would minimize the appearance of wrinkles. (Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021) Papain-treated samples show a slightly higher collagen content, possibly because of papain on collagen proteolysis. This suggests that papain might improve skin firmness and elasticity.  (Banchhor, 2008)

The enzyme papain in papaya can help decrease inflammation. The protein-dissolving papain is found in many exfoliating products, which helps in many skin problems. These exfoliating products help reduce acne by removing dead skin cells that clog pores. Another study suggested that Papain removes damaged keratin that can build up on the skin and form small bumps. Papaya is also rich in Vitamin A and might play a role in developing or treating acne. Retinol is the topical form of Vitamin A, which can help treat or prevent inflammatory acne lesions. (Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021)

Papain is very powerful in hydrolyzing fibrous protein and connective tissue. Kang and Rice reported that papain solubilized 15 % of connective tissue protein; Scientific evidence shows that this may improve the appearance of the skin. Papain degrades damaged, misfolded, and potentially harmful proteins and provides free amino acids required to synthesize new proteins. This helps tissue repair and encourages the growth of skin cells, which might be associated with the rejuvenation effect of papain on the skin. According to recent work, papain also acts as a powerful shield against the damaging effects of radiation on the skin. Its collective impact on the skin (Hydration. Hydrolyzing, Rejuvenation, Immune response, debridement, and exfoliative properties) reduces the signs of aging skin.  (Banchhor, 2008)

Carica papaya, a tree-like herb, is cultivated in more than 50 tropical and subtropical countries worldwide. The parts [leaves, fruit (ripe and unripe), seeds, and latex] are used as food and traditional medicine in several ways for several diseases. Papaya, with a variety of phytochemicals like carotenoids, polyphenols, benzyl isothiocynates, benzyl glucosinates, prunasin (cyanogenic substrate), papain and chymopapain, alkaloids, phenolic compounds, flavonoids, vitamins (A, C, E), carotenoids, cyanogenic glucosides, cystatin, and glucosinolates exhibits significant health benefits ranging from digestive to immune modulation. These compounds have antioxidant, chemoprotective, anti-diabetic, anti-bacterial, anti-plasmodial and anti-fungal activities. Papaya aqueous leaf extract was evaluated for immunomodulatory and anti-tumor activities through cytokine modulation. (Heena & Sunil, 2019) Carica papaya, a tree-like herb, is cultivated in more than 50 tropical and subtropical countries worldwide.

(Heena & Sunil, 2019) The juice of the leaves of the Carica papaya plant from the family Caricaceae may help to escalate the platelet levels in patients suffering from dengue. (Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021)

Oxidative stress occurs due to excessive ROS production, which will cause oxidative damage to tissues. Consequence effects of oxidative stress are known to cause inflammation, leading to the development of various health conditions, including AD, rheumatoid disease, cardiovascular diseases (CVDs), cancers, cataracts, as well as cosmetic issues, such as the formation of wrinkles and loss of elasticity of the skin. (Yew Rong Kong, Beneficial Role of Carica papaya Extracts and Phytochemicals on Oxidative Stress and Related Diseases: A Mini Review, 2021) 

The Carica papaya counteracts oxidative stress via its potent antioxidant properties. The antioxidant properties of the Carica papaya plant might be attributed to the different chemical constituents that the plant contains, including caffeic acid, myricetin, quercetin, rutin, α-tocopherol, papain, kaempferol steroids, alkaloids, and saponins. Several studies have suggested that Carica papaya extract's antimicrobial properties aided wound recovery. Therefore, more studies should be done to unravel the benefits of the Carica papaya.  (Yew Rong Kong, Beneficial Role of Carica papaya Extracts and Phytochemicals on Oxidative Stress and Related Diseases: A Mini Review, 2021) 

Papaya is high in fiber and has a good water content, both of which help with constipation and promote regularity and a healthy digestive tract. The papaya's fiber, vitamins, and potassium content help prevent heart disease. An increase in potassium and a decrease in sodium will help prevent cardiovascular disorders.   According to many studies, eating papaya has shown that it helps to contract the uterine muscles. It produces the required body heat as well as providing carotene. This stimulates the hormone estrogen, which helps induce periods or menses more frequently. (Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021) (Banchhor, 2008)

Dengue is an acute infectious disease caused by mosquitoes and associated with significant mortality and morbidity. Clinically, dengue causes moderately high-grade fever, rash with severe aches, primarily severe backache, and pain behind the eyes. In severe forms, symptoms such as vomiting, pain in the abdomen, red spots, reduction in urine output, change in alertness, and bleeding can occur. The red flag sign, citing the severity of severe dengue, is a fluid leak from blood vessels and capillaries from the nose, gums, skin, lung vessels, intra-abdominal areas, etc. Pathogenesis of bleeding involves leakage of plasma from the blood vessels. It seems to be due to the destruction of platelets through the complement system or depression of bone marrow due to dengue viral infection or both. Based on this systematic review and meta-analysis, it can be concluded that C. papaya leaf extract has a definitive role in improving the platelet count in patients with dengue. The community instantly took up papaya in the treatment of dengue due to its perceived beneficial effect on the platelet count. The literature cites the therapeutic effects of aqueous extract of papaya (Carica papaya) leaves that are presumed to be due to several active components (flavonoids, alkaloids, enzymes, and minerals), which may have antioxidant and immunomodulatory effects.  (Jaykaran Charan, 2016)(Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021) (Banchhor, 2008)

The flesh of the ripe papaya is usually eaten raw. It makes an excellent breakfast or dessert fruit. It is generally combined with other tropical or citrus fruits in fruit cocktails or salads. Because it contains an enzyme that breaks down protein, fresh papaya cannot be used in gelatin salads and desserts; various products such as drinks, jams, marmalades, nectars, ice cream, sherbet, yogurt, and pie may be made from ripe papayas. Green papayas are sometimes cooked as vegetables and can be pickled or candied. Papain, the protein-splitting enzyme in green papaya, is extracted and sold commercially as a meat tenderizer. Papain extract is also used to treat specific intestinal and digestive problems.

As a folklore medicine:

From time immemorial, the papaya plant, including its leaves, barks, roots, ripe & unripe fruits, and juices, are used as a traditional medicine. Papaya is a good source of Vitamin A, C, E & K as well as folate and fiber addition, and it is fat-free, cholesterol-free, and low in sodium. An average serving of a fruit dish has only 70 calories. (Parle Milind G. , 2011)                                     

 Papaya has a range of health benefits…

• Age-related macular degeneration.
• Asthma prevention.
• Cancer.
• Bone health.
• Diabetes.
• Digestion.
• Heart disease.
• Inflammation.
• Skin & healing.
• Hair health.
• Nutrition.

While papaya is an incredible tropical fruit, it has certain possible risk factors to consider before making any consumption decision. The risk factors depend on the usage of this fruit.

Latex, a mix of the proteolytic enzymes present in the papaya fruit, varies in quantity depending on the ripeness of the fruit. Ripe papaya has a comparatively lower concentration of latex than unripe papaya. So, applying unripe papaya can cause some people skin irritation, blister formation, or allergic reactions.  (Meesha Deshpande (Guide), Benefits of Papaya Fruit and its leaves to Treat Malaria or Dengue and, 2021)

According to the Study, there are no adverse/ toxic effects upon consumption of Papaya fruit over a long time except that it causes infertility. However, the leaves & roots of Carica papaya contain cyanogenic glucosides, which form cyanide, leading to fatal consequences. (Parle Milind G. , 2011)

1. When should papaya be eaten?

Incorporating papaya into the morning routine offers multiple advantages, including reducing the risk of heart disease, lowering cholesterol levels, and preventing strokes. Moreover, consuming papaya on an empty stomach can enhance skin health, minimize acne, and prevent premature ageing.

Experts recommend consuming papaya on an empty stomach, preferably in the morning, as it helps detoxify the body and facilitates healthy bowel movements.

2. When papaya should not be eaten?

Papaya latex might also cause irritation and blistering on the skin, so hypersensitive people are generally advised to consult a doctor before taking it. Excessive consumption of Papaya must be avoided as it may cause flatulence and loose motions. 

3. Who should not eat papaya?

Latex allergy: If you have a latex allergy, use caution with papaya or products that contain papaya. You may also be allergic to papaya. Papain allergy: Unripe papaya contains papain. If you are allergic to papain, avoid unripe papaya.

Pregnant women. Unripe and semi-ripe papaya should be avoided during pregnancy because it can cause uterine contractions due to its laxative properties. 

Kidney stones. We praise papaya for being high in vitamin C.

Heart issues and hypothyroidism should also be avoided by papaya.

4. Who extracted enzymes from papaya?

Papaya enzyme was first named in the late 19th century by Wurtz and Bouchut, who partially purified the product from papaya sap and recognized it as a constituent in the latex of tropical papaya fruit. It is obtained by making incisions on the epicarp of unripe papaya, collecting and drying the latex which flows out. More active papain can also be obtained from a greener or unripe fruit. Papain, a member of the papain superfamily, possesses inherent proteolytic properties vital in living organisms' biological processes. 

5. Where is papaya grown in India?

Papaya is mainly cultivated in Andhra Pradesh, Karnataka, Gujarat, Orissa, West Bengal, Assam, Kerala, Madhya Pradesh and Maharashtra.

6. What papaya contains?

The prominent medicinal properties of Papaya include Anti-fertility, Uterotonic, Diuretic, Anti-hypertensive, Hypolipidemic, Anti-helmintic, wound-healing, Anti-fungal, Anti-bacterial, Anti-tumor, and Free radical scavenging activities. Phytochemically, the whole plant contains enzymes (Papain), carotenoids, alkaloids, monoterpenoids, flavonoids, minerals & vitamins. (Parle Milind, 2011) Both leaf and fruit of the Carica papaya Linn. possess carotenoids, namely β- carotene, lycopene, and anthraquinones glycoside. (Vijay Yogiraj, 2014)                     

The tropical fruit Papaya contains Vitamins A, B, C, D, and E, fiber, and healthy plant components. The antioxidants present may help reduce oxidative stress, lowering the risks of other diseases. Adding to that, it may also help against sun damage and defend against skin wrinkling. Papaya is delicious when eaten ripe, alone, or easily combined with other foods. (Meesha Deshpande (Guide), 2021)

7. What is papaya extract?

Traditionally, all parts of papaya, including roots, seeds, flowers, fruit, latex, barks, and leaves, have been used to treat several diseases in various world regions. The fruit, seeds, or leaf extracts of papaya have been shown to possess cytotoxic and anti-proliferative activities and were assessed for estrogen.

Study indicates that papaya leaf extracts health benefits are impressive. They contain calcium and vitamins A, B, C, D, and E. The antioxidants filled in the leaves fight free radicals that go into the body. Leaf extracts play a vital role in increasing the platelet count. Beyond any question, it offers a cheap and possibly effective treatment for dengue. The flavonoids and other phenols in the papaya leaf have been encouraged to provide beneficial properties.

8. What is papaya enzyme good for?

Enzymes are already found within our bodies to help our digestive system function correctly by breaking down the food we consume to release the nutrients around our bodies and into our bloodstream. The papaya enzyme, taken from the unripe fruit of the papaya tree, is a natural source of papain – an enzyme found in the white fluid (latex) that occurs in raw papaya fruit. It is a protease, meaning it breaks down proteins. Papain contains substances that might help fight infection and heal wounds.

9. Does papaya extract make hair soft?

According to a study, Vitamin A in papaya can positively affect hair by helping the scalp produce sebum, which nourishes, strengthens, and protects your hair. Enriched with enzymes of papain, chymopapain, and vitamins A and C with antioxidant characteristics, papaya extracts nurture and condition dull, damaged hair. Using papaya for hair nourishes the scalp and strands immensely, leaving the hair feeling soft and hydrated. It also reduces friction between the strands of your hair and makes it manageable. 

10. Does papaya extract safe during pregnancy?

The results of a study suggest that regular consumption of ripe papaya during pregnancy may not pose any significant danger. However, the unripe or semi-ripe papaya (which contains a high concentration of latex that produces marked uterine contractions) could be unsafe during pregnancy. 

11. Does papaya extract a bleaching cream?

According to a Study, Papaya contains the enzyme papain, which is more like bromelain (an enzyme of Pineapple) and removes superficial stains. Papain enzyme is found more in unripe papaya than in ripe papaya. The experiment shows that papaya latex & papaya fruit extract have tyrosinase inhibitory activities.

12. Are papaya pills safe during pregnancy?

The results of a study suggest that regular consumption of ripe papaya during pregnancy may not pose any significant danger. However, the unripe or semi-ripe papaya (which contains a high concentration of latex that produces marked uterine contractions) could be unsafe during pregnancy. But It is still not clear. We need more investigation.

13. Can papaya enzyme cause diarrhea?

While papaya is a source of fiber and is suitable for digestive health, eating too many may have a laxative effect, causing diarrhea and an upset stomach.

14. Papaya can get periods.

Papaya can regularize period circle. Eating papaya regularly helps in contracting the uterus muscles. Apart from producing heat in the body, the fruit contains carotene. This substance stimulates or regulates estrogen hormone levels in the body. Naturally, this induces periods or menses more frequently.

15. How much papaya leaf extract increases platelets?

According to a study, Numerous case reports have shown that administering C. papaya leaf extract (CPLE) in various doses increases platelet count in Dengue in humans. Most recently, an open-label randomized controlled trial of 228 patients already receiving standard treatment for Dengue investigated the effect of juice from 50 g of fresh C. papaya leaf daily for three consecutive days showed a significant increase in mean platelet count at 40 hours and 48 hours in the intervention group compared to standard of care alone. (Katherine Hampilos, 2019 )
