that help to treat and manage various diseases. The many
parts of the plant have been used in traditional medicine
to manage conditions like malaria, gastroenteritis, vomiting,
diarrhea, dysentery, wounds, ulcers, toothache, coughs, sore
throat, inflamed gums, and a number of other conditions
. This plant has also been used for the controlling

the total extracts of P. guajava leaves, growing at Fort
Valley State University, using various aqueous and organic
solvents to establish if it is effective against killing or
inhibiting the growth of foodborne bacterium Staphylococcus
aureus, Escherichia coli, Salmonella enteritidis, and
