“…guava leaves can interfere with multiple signaling cascades linked with tumorigenesis and provide a source of potential therapeutic compounds for both the prevention and treatment of cancer.”
Male fertility – A Nigerian study found guava leaf extract to increase male fertility in rats without toxic side effects and with implications for humans.

Just for fun:
“The alcoholic extract of Pisidium guajava (Guava) leaves was found to act as a good corrosion inhibitor for mild steel in 1 M phosphoric acid medium. A maximum inhibition efficiency of 89% was obtained for an inhibitor concentration of 800 ppm in the weight loss studies for 1 h immersion time.”
