Have you ever tasted guava? You might have experienced its mouthwatering sweetness mixed with a light sour taste. This fruit is one of my favorite food during my younger years. I even visit the guava tree in our backyard for its fruit.

Soon, its seeds spread throughout the entire world as the world expeditions continued. And now, we can find it in Asia, especially in thickets and low-altitude forests.

Guava also promises a lot of health benefits. When I was still a little boy, my grandmother would even wash my wounds with a warm decoction from guava leaves. The elders in my country treat it as an effective antiseptic and antibacterial.

They even used it for local circumcision. And believe it or not, they didn’t do the circumcisions through surgery in hospitals. It occurred either under a wooden hammer or knife. And they used guava leaves to wash and disinfect that wound.

Years passed, I’m now an already professional pharmacist. I realized that the guava health claims of my grandparents were true. Guava facts, tested in the laboratory, and even history.
