Nutrition, Traditional Use and Research
The statements below describe nutrition facts, traditional use and published research. They are not health claims for our products.
- Guava leaves have a long history of use in traditional medicine in many tropical countries, for example as a tea. This is a traditional use and has not been confirmed by sufficient scientific evidence.
- Guava leaves contain antioxidants and other nutrients.
- Some laboratory and animal studies have examined guava leaf extract: in rats in relation to diarrhea, in mice in relation to inflammation of the colon and antibody production, and in laboratory tests against bacteria such as E. coli and Salmonella. These are early findings from cell and animal studies, and no health effect in people can be concluded from them.
- To make guava leaf tea, steep fresh or dried guava leaves in hot water for 5–10 minutes.
- Guava leaves are generally well tolerated, but side effects such as nausea, vomiting or diarrhea can occur. If you experience any side effects, stop using guava leaves and consult a doctor.
