While you can have diarrhea because of viruses, it can also be caused by bacteria from contaminated water or food. A study was done to evaluate the spasmolytic activity of guava leaf and was found that a compound called “aglycone quercetin” is responsible for spasmolytic activities, which is formed when flavonoids of guava leaves are hydrolyzed by the gastrointestinal fluids. The observed inhibition of Gram-positive bacteria, Bacillus cereus and Staphylococcus aureus, suggests that guava possesses compounds containing antibacterial properties that can effectively suppress the growth when extracted using methanol or ethanol as the solvent.
