Indian Guava (Psidium guajava L.) contains high concentrations of phenolic compounds including gallic acid and quercetin that provide antioxidant protection by scavenging free radicals and boosting antioxidant enzymes like glutathione peroxidase and catalase. The fruit's bioactive compounds demonstrate antimicrobial effects through bacterial cell membrane damage and anti-inflammatory activity via COX-2 and NF-κB pathway suppression.
Reported Benefits (Provisional)
Origin & History
Indian Guava (Psidium guajava) is a tropical and subtropical fruit native to India, Southeast Asia, and Central America. Revered in Ayurvedic and indigenous Indian medicine, guava has been used for centuries to support digestion, immunity, and cardiovascular health. Exceptionally rich in vitamin C, fiber, and polyphenols, guava serves as a potent superfruit for metabolic balance, anti-inflammatory support, and holistic wellness.
Research Narrative (Provisional)
Scientific studies support Indian Guava's benefits for gut microbiome balance, immune and antimicrobial effects, blood sugar regulation, cardiovascular protection, and anti-inflammatory skin benefits. Research validates its traditional uses, highlighting its rich nutrient profile and bioactive compounds.

Nutritional Profile
- Vitamin C: Supports immune function and collagen formation. - Quercetin: Offers anti-inflammatory and metabolic health benefits. - Carotenoids: Provide antioxidant and vision support. - Polyphenols: Deliver cellular protection and anti-inflammatory effects. - Tannins: Contribute digestive and antimicrobial properties. - Potassium: Aids in electrolyte balance and cardiovascular function. - Dietary Fiber: Supports gut and metabolic health. - Bioactive Alkaloids: Contribute to immune and metabolic resilience.
Reported Mechanism (Provisional)
Indian Guava's phenolic compounds including gallic acid, chlorogenic acid, and flavonoids like quercetin and myricetin scavenge free radicals while enhancing antioxidant enzymes glutathione peroxidase, catalase, and superoxide dismutase. The compounds inhibit acetylcholinesterase and butyrylcholinesterase enzymes (IC₅₀ values 44.95-56.11 µg/mL) and suppress inflammatory pathways including COX-2, NF-κB signaling, and cytokine production. Antimicrobial activity occurs through bacterial cell membrane disruption causing protein and ion efflux.
Clinical Narrative (Provisional)
Current evidence is primarily from in vitro and animal studies rather than human clinical trials. In vitro research shows guava extract induced 30-fold increases in apoptotic colon cancer cells compared to controls. A 28-day study in 25 Wistar rats demonstrated significant increases in antioxidant enzymes and reduced oxidative stress markers with stem-bark extract. Human clinical trials with quantified outcomes for blood glucose reduction, infection cure rates, or other therapeutic endpoints are lacking in current research.
