Herbal remedies, or phytotherapy, is the science of using herbal medicines to treat the sick. Natural herbs are the highly esteemed source of medicine throughout human history. Psidium guajava (PG), the common Guava tree popularly known as ‘poor man's apple of the tropics is an important dietary plant having a long history of traditional use for a wide range of ailments. The medicinal properties of guava fruit, leaf and other parts of the plant are also well known in the indigenous system of medicine. In view of the immense medicinal importance of PG, this study reveals the efficacy of PG in the amelioration of diabetes, a chronic metabolic disorder that affects the body's ability to produce or use insulin. Treatments could be achieved by the use of synthetic oral hypoglycaemic agents. But due to the major to minor side effects that have been reported so far there is a persistent need to search for safe and effective alternatives.
