Guava

Psidium guajava

Also known as: Psidium guajava, common guava

A small tropical evergreen tree in the myrtle family (Myrtaceae), native to Mexico, Central America, and northern South America. Carried by Spanish and Portuguese ships within decades of Columbian contact — now naturalized and culturally embedded across the entire global tropics. The fruit is central to Indian, Caribbean, Mexican, Brazilian, Pakistani, Bangladeshi, Filipino, and African cuisines. Pink-flesh and white-flesh cultivars are both common. The leaves are widely used in traditional medicine across the species' new global range for diarrhea and gastrointestinal complaints.

Scientific

Psidium guajava is in the myrtle family Myrtaceae — same family as [[eucalyptus]], [[clove]], and (closer to Psidium) the strawberry guava (P. cattleyanum). Native range covers Mexico, Central America, and northwestern South America.

The fruit is a many-seeded berry with white, pink, or yellow flesh depending on cultivar. Vitamin C content is exceptionally high — guava typically has 4x the vitamin C of orange by weight.

Cultural and historical

Spanish and Portuguese ships carried guava across the tropics within decades of Columbian contact. By the 17th century the species had been planted, naturalized, or integrated into local cuisines across:

India (where guava is amrood and is foundational to home gardening and street fruit culture)
The Philippines (where bayabas is both a food and a folk-medicinal plant)
Hawaii and the Pacific Islands
Sub-Saharan Africa
North Africa

The diffusion is one of the most rapid and complete plant naturalizations in tropical agricultural history.

Brazilian goiabada (a thick guava paste, often eaten with cheese in the Romeu e Julieta combination), Mexican agua de guayaba, Indian guava with chaat masala, Cuban guava-and-cheese pastry are all distinct regional culinary traditions building on the same species.

The leaves are used in traditional medicine across most of the species’ new range. Guava leaf tea for diarrhea and gastric complaints is documented in Mexican, Caribbean, Indian, Filipino, and African traditional medicine — independent traditions converging on the same therapeutic use, likely reflecting genuine antibacterial activity of the leaf compounds.

Global production

Top producers: India (by a wide margin), China, Thailand, Indonesia, Brazil.
