Research has shown that guava leaf has antioxidant effects beneficial to the heart, i.e. cardioprotective properties and improved myocardial function. In two randomized human studies, the consumption of guava fruit for 12 weeks was shown to reduce blood pressure by an average 8 points, decrease total cholesterol levels by 9%, decrease triglycerides by almost 8%, and increase HDL cholesterol by 8% (Jimenez-Escrig, et al., 2001; Conde, et al., 2003). In other animal studies guava leaf extracts showed demonstrable analgesic, sedative, and central nervous system (CNS) depressant activity, as well as cough suppressant actions (Jaiarj et al., 1999; Singh et al., 1993; Singh et al., 1992; Shaheen et al., 2000).
