Phytochemical Properties and Health Benefits of Psidium Guajava
Summary
Psidium guajava, commonly known as guava, is valued for a rich array of phytochemicals including flavonoids, phenolic acids, triterpenes and essential oils. Leaves, fruit and by-products yield quercetin, kaempferol, catechins, gallic acid and a spectrum of terpenoids that confer potent antioxidant, antimicrobial, anti-inflammatory and metabolic regulatory activities. These bioactives scavenge free radicals, inhibit microbial growth, modulate carbohydrate-digesting enzymes and regulate lipid metabolism, supporting traditional uses in gastrointestinal disorders, diabetes management, cardiovascular protection and wound healing. Advances in extraction and formulation have enhanced solubility and stability of hydrophobic constituents, expanding the potential for functional foods, nutraceuticals and complementary medicines. The convergence of ethnobotanical knowledge with modern analytical and delivery technologies underscores the global relevance of P. guajava as a source of safe, effective bioactives with applications in chronic disease prevention and health promotion.
