Documented side effects of African Mango include dry mouth, digestive problems, insomnia and flu symptoms, Drugs.com reports. These findings are based on limited clinical research on a small sample of patients, as of 2015.
Although research has shown that African Mango has positive effects for conditions such as diabetes and obesity, relatively little is known about the entire scope of its medical benefits as of 2015, Drugs.com explains. Even less is known about how African Mango interacts with other drugs, so people should take caution and consult a doctor before mixing it with prescription medications. Toxicology tests performed on laboratory rats resulted in no deaths among those tested with high doses of African Mango seed extract over a span of a week.
