Guava fruit is good for health but guava leaves also have other benefits, such as treating digestive diseases, and can reduce the risk of cardiovascular diseases and cancer.
Effects on the digestive system
One of the most notable uses of guava leaves is their ability to help treat digestive problems. Studies have shown that guava leaves contain many polyphenols and flavonoids that have strong antibacterial properties, helping to prevent bacteria that cause diarrhea and intestinal inflammation. A study in the Journal of Phytotherapy Research showed that guava leaf extract can reduce symptoms of diarrhea and intestinal inflammation thanks to its ability to inhibit the activity of harmful bacteria such as Escherichia coli and Salmonella.
Anti-inflammatory and antioxidant
Guava leaves are also known for their anti-inflammatory and antioxidant properties. Polyphenolic compounds in guava leaves such as quercetin and kaempferol have been shown to reduce inflammation, support the immune system, and slow down the aging process. Guava leaf extract has the ability to inhibit the production of free radicals, thereby minimizing cell damage and preventing diseases related to oxidative stress such as cancer and cardiovascular disease.
Effects on diabetes
Guava leaves also have a positive effect on diabetes, especially in regulating blood sugar levels. Guava leaf extract can help reduce blood glucose levels in people with type 2 diabetes. Compounds in guava leaves help improve the body's ability to use insulin, while reducing insulin resistance. This can reduce the risk of developing complications of diabetes.
Reduce the risk of cardiovascular disease
The ability to reduce cholesterol and blood pressure - two important risk factors for heart disease - is also one of the effects of guava leaves. A study in the Journal of Clinical Biochemistry and Nutrition showed that the use of guava leaves can reduce bad cholesterol (LDL) and increase good cholesterol (HDL) in the blood. Thereby supporting the prevention of cardiovascular disease.
Along with guava fruit, guava leaves have many good effects on health, but if using guava leaves as a treatment method, it still requires the guidance and supervision of a doctor, especially for people with special health conditions.
