According to Healthline, guava leaves and fruits both contain many nutrients that are beneficial for health. While guava fruits are rich in vitamin C, fiber, potassium and antioxidants, guava leaves have long been used in traditional medicine in many Asian countries in the form of herbal tea or extract.
One of the most studied benefits of guava leaves is its ability to support blood sugar control. Some studies show that guava leaf extract can help improve blood sugar levels, increase insulin sensitivity and support blood sugar control for a long time. These results show that guava leaves have the potential to support people with diabetes or those at risk of the disease.
In addition, guava leaves and fruits are also highly appreciated for their benefits to cardiovascular health. Scientists believe that the content of antioxidants, potassium and fiber in guava can contribute to protecting the heart, supporting blood pressure control and improving cholesterol levels. Some studies have noted that guava leaf extract is associated with reducing LDL cholesterol (bad cholesterol) and increasing HDL cholesterol (good cholesterol).
For the digestive system, guava is a rich source of fiber. Adding guava to the diet can support bowel movements, help prevent constipation and maintain a healthy digestive system. Some studies also show that guava leaf extract has antibacterial properties, which can contribute to reducing the severity and duration of diarrhea.
Thanks to being low in calories but rich in fiber, guava is also a suitable food for people who are controlling their weight. Fiber helps create a longer feeling of fullness, while vitamins and minerals support the body in providing essential nutrients.
In addition, guava is also famous for its very high vitamin C content. Just one guava can provide a quantity of vitamin C exceeding the recommended daily needs, contributing to supporting the immune system to function more effectively. Antioxidants in guava are also said to be beneficial for the skin, helping to protect cells from harmful agents and slow down the aging process.
However, experts note that guava leaves and guava leaf extracts should not be considered a substitute for medication. People with chronic diseases or using medication should consult a doctor before using them regularly.
