Carica Papaya may have potential health benefits for blood related medical problems.

The Pakistan Journal of Biological Sciences, issue of March 2011, reported a study on the phytochemistry and heamotological potential of the ethanol seed, leaf and pulp extract of Carica papaya. In this study, it was identified that the phytochemical contents in the seeds, leaf and pulp of Carica papaya were almost the same but in varying proportions. It was also observed that the phytochemicals found in Carica papaya significantly improved (P<0.05) the production of certain blood parameters in treated albino rats. This study suggests that Carica papaya may have potential health benefits for blood related medical problems. (Source :

Carica Papaya may have Anti diabetic health benefits

The Journal of Natural Product Research, issue of December 2011 reported that a study done in INFORMM, Malaysia identified the phytochemicals in Carica papaya that may have anti diabetic properties. The ethanol extracts of Carica papaya and Pandanus amaryfollius were administered to a group of streptozotocin induced diabetic rats to measure its anti diabetic effects. Results have shown that there was a significant reduction (P<0.05)in the blood glucose level in the Carica papaya treated group in comparison to a control group. Histologically the pancreas of the treated groups indicated significant regeneration of the β-cells and liver tissues indicated a reduction in fatty changes and pyknotic nucleus. Moreover, the kidney tissues of the treated groups indicated significant recovery in the cuboidal tissue. The study suggests that the phytochemicals found in C. Papaya and P. amaryfollius may be responsible for the anti diabetic health benefits. (Source:

Carica papaya Health Benefits for Digestive Disorders

In a published report in Nuero Endocrinology Letters 2013, a research was done in Vienna, Austria to verify the folkloric health benefits of Carica papaya for digestive disorders. Clinical trials involving volunteers with chronic (prevailing) indigestions and dysfunctions in the gastrointestinal tract were given papaya preparation (Caricol). They were compared to a control group given a placebo. Results have shown that there was a significant improvement in the symptoms of “indigestion” and “bloating” for those under the papaya preparation as compared to the control group. The study concludes that the papaya preparation (Caricol®) contributes to the maintenance of digestive tract physiology. It ameliorates various functional disturbances, like symptoms of IBS.

Papaya and Pregnancy: Safety and Side Effects

The British Journal of Nutrition, August 2002. published a study done in the Department of Obstetrics and Gynaecology, National University, Singapore on the common belief of some Asian communities that eating papaya can be unsafe for pregnant women. In a laboratory experiment, the effects of ripe papaya blend (500 ml/l water) and papaya crude latex to the uteri of pregnant Sprague-Dawley rats was compared to a control group given with water only. Results have shown that ripe papaya has no adverse or noticeable side effects, while the crude latex induced spasmodic contraction of the uterine muscles. The study suggests that normal consumption of ripe papaya during pregnancy may not pose any significant danger. However, the unripe or semi-ripe papaya (which contains high concentration of the latex that produces marked uterine contractions) could be unsafe in pregnancy. (Source:
