 |
Overview Guava is a small tropical tree that grows up to 35 feet tall; it is widely grown for its fruit in tropics. It has a distinctive fresh aroma with sweet musk odor and the vitamin C content is higher than in citrus. Guava is considered a super-fruits, being rich in vitamins A and C, omega-3 and -6 polyunsaturated fatty acids and high levels of dietary fiber. In Suriname's traditional medicine, the whole guava-plant is used. The leaves and bark are used for an effective treatment of (acute) diarrhea and dysentery; for stomach upsets and to regulate menstrual periods. Guava leaves and bark have been used to treat diabetes. This plant has anti-inflammatory and analgesic properties. Guava is rich in the antioxidant lycopene (non-provitamin A carotenoid), which has recognized anti-cancer properties. These are preventions and treatments of cancers of the lung, stomach, bladder, cervix, skin, and especially, prostate. It may lower the risk of heart disease, lower LDL ("bad" cholesterol), enhance the body's defenses, and protects enzymes, DNA, and cellular fats. For the tincture and infusion only the leaves are used. Constituents Ascorbic acid, pectin, fatty acids, tannins, phenols, triterpenes, essential oils, saponins, carotenoids, lectins, flavonoids (quercetin) and gallic acid. Pharmacology Preliminary medical research in extracts from the leaves and bark are implicated in therapeutic mechanisms against cancer, bacterial infections, inflammation and pain. For instance, the essential oils from the leaves have shown strong anti-cancer activity. The numerous tannins, polyphenolic compounds, flavonoids, ellagic acid, triterpenoids, guiajaverin, quercetin, and other chemical compounds present in the plant are speculated to account for the observed anti-inflammatory and analgesic effects of the plant's leaf extract. Quercetin is thought to contribute to the anti-diarrhea effect of guava. Obtained research results suggest that the spasmolytic activity of the Psidium guajava leaf remedy is mainly due to the aglycone quercetin, present in the leaf and in the extract mainly in the form of five flavonols. Research suggests that Guava has cardioprotective effects against myocardial ischemia-reperfusion injury in isolated rat hearts, primarily through their radical-scavenging actions.
