Medicinal role of guava leaf extract
Psidium guajava is an evergreen shrub whose height can reach upto 15 metres. It is a native to Mexico and Central America but can be grown in warmer climates as in Asia including India. The plant's young leaves have been used historically in Mexico to prepare an extract which is consumed on daily basis to cure diseases, such as gastric ulcers, acute diarrhoea, flatulence and abdominal pain. In parts like Egypt, it has been used to treat dry cough and pulmonary diseases. In china, it is used as an an anti-inflammatory and haemostatic agent.

The bark of the tree is used to treat diarrhoea and gastro-intestinal problems while the flower part is used to treat bronchitis and pulmonary diseases. The fruit part is found to be very helpful in the prevention of bleeding gums and to maintain oral hygiene. These wide implications in the medicinal field are due to the presence of flavonoids, tannins, lectins, phenols, anthocyanins, alkaloids, carotenoids, essential oils, triterpenes and vitamin C. It has also been found that, the guava leaf extract is very much efficient in the prevention of biofilm formation by certain bacteria, namely Pseudomonas aeruginosa which causes gingivitis in humans. Due to the presence of polyphenols, it possesses anti-inflammatory and anti-oxidant activity. Some studies have shown that, the leaf extract is found to be effective against cancer cell lines of colon, prostate, epidermal and melanoma. It also seems to be effective against CNS defects as a result of the presence of Quercetin. The most important aspect is that, it does not have any side effects except some constipation problems in severe cases.
