Some evidence suggests that guava can improve blood sugar control.

This is good news for people with diabetes or those at risk.
A few studies involving humans have also shown impressive results.

Flu
Drinking guava leaf tea may help people fight off the flu.
In a 2012 test tube study , guava leaf tea showed promise as an antiviral agent for flu treatment. The researchers found that the tea inhibited the growth of the virus that causes the flu.
The antiviral effect of the tea may result from the leaf’s flavanols, which are a natural antioxidant.
Confirming the effects in humans will require further research.
