Chronic diseases such as cancer, diabetes, neurodegenerative and cardiovascular diseases are characterized by an enhanced state of oxidative stress, which may result from the overproduction of reactive species and/or a decrease in antioxidant defenses. The search for new chemical entities with antioxidant profile is still thus an emerging field on ongoing interest. Psidium guajava leaves have traditionally been used to manage several diseases such as rheumatism, diarrhea, diabetes mellitus, and cough. The results of the free radical scavenging activity of the DPPH radical assay method for antioxidant activity have shown that the Psidium guajava extract exhibits significant scavenging activity.
