Guava leaves contain many compounds such as polyphenols, flavonoids, tannins and some other antioxidants.
If you want to use guava leaf water as a herbal drink to supplement your diet, you should choose clean guava leaves, without signs of pests and especially avoid leaves with the risk of pesticide residues. Leaves need to be washed thoroughly under running water before processing.
Fresh leaves or dried leaves can be used to make water. Drinking water should be diluted, without adding sugar, instead of cooking concentrated water into a thick decoction and drinking many times a day.
People who have never used it can start with small amounts to monitor the body's reaction.
The content of active ingredients in leaves can vary depending on guava variety, leaf age, planting conditions and processing methods.
According to the World Health Organization (WHO), high blood pressure is a condition of excessive pressure in blood vessels and can lead to serious complications such as heart disease, stroke and kidney damage if not controlled.
WHO says many people with hypertension have no obvious symptoms, so regular blood pressure measurements and adherence to treatment are important.
More evidence-based measures include healthy eating, reducing salt intake, increasing vegetables and fruits, maintaining a proper weight, regular physical activity, and taking medication as directed when necessary.
Adults should limit the amount of salt to less than 5g per day, equivalent to less than 2g of sodium, and increase vegetables and fruits in their diet.
Guava leaf water can be used as a herbal drink to support a healthy diet.
People taking medication should continue to take medication according to the prescription, monitor blood pressure regularly and talk to a doctor or pharmacist if they intend to use it regularly.
