Guava
Psidium guajava
Long before it traveled the world in fruit bowls, guava was already a household plant across Central and South America, where communities steeped its young leaves into a simple, astringent tea to settle an upset stomach after meals. As the tree spread through the Caribbean, Africa, and Asia in the wake of trade and colonization, folk healers in many of these regions adopted the same leaf tea, and it also became a common home gargle for minor mouth and throat irritation. The fruit itself, soft, fragrant, and full of small seeds, was treasured simply as a generous source of vitamin C long before that nutrient had a name.

Traditional preparations.
A simple infusion made from the young leaves, used across the tropics as an after-meal tea when the stomach feels unsettled.
Traditionally, a tea is made by steeping 1 teaspoon of dried, crumbled guava leaves in 250 ml of just-boiled water for 10 minutes, then straining and sipping slowly, warm.
A cooled, well-strained batch of the same leaf tea has traditionally been used as a mouth rinse or gargle for minor mouth and throat irritation.
Steep 1 teaspoon of dried guava leaves in 250 ml of hot water for 10 minutes, strain well, and let the tea cool completely before using it as a gargle or mouth rinse.
Safety.
Guava is a safe, common fruit; the leaf tea has been studied for lowering blood sugar, so those on diabetes medication should watch for an added effect.
