Since ancient times, we used guava leaf tea from Psidium gujava Linnaeus as a remedy for gastroenteritis and paediatric diarrhoea. The well-known tropical tree Psidium guajava, or guava, is widely farmed for its fruit. Guava has a lengthy history of use as a medicine in many nations. Treatments for diarrhoea, dysentery, gastroenteritis, hypertension, diabetes, cavities, pain alleviation, and improved locomotor coordination can all be achieved using this herb. For treating oral ulcers, cough, diarrhoea, and some wounds with swollen gums, it's leaf extract is employed. Its fruit is a good source of minerals, iron, calcium, phosphorus, and vitamins A and C. It has a high concentration of organic and inorganic substances like secondary metabolites, such as polyphenols, antioxidants, antiviral substances, and anti-inflammatory substances. Guava's phenolic chemicals aid in the treatment of malignant cells and delay premature skin ageing. Terpenes, caryophyllene oxide, and p-selinene all have calming effects when present. In this review we focused on the pharmacological, phytochemical constituents and antimicrobial activities of this plant.
