2. Can cause Delayed Allergic Reaction
Mangoes contain a chemical compound known as urushiol. This is an oil that is present in poison ivy, oak, and sumac. People that are allergic are likely going to get a skin rash around their mouth, which is same to the red and itchy problem caused by contact with other urushiol-containing plants.
Now, one tricky thing about reactions gotten from this compound is that it doesn’t occur immediately. Most times it takes about three days before you start noticing reactions on your body, making if very difficult to determine the cause.
So if you recently consumed mango and noticed reactions on your body later on, then you need to stop eating mango and see a doctor.
