Background
- Yerba mate (Ilex paraguariensis) is an herb prepared as a traditional drink common in South American countries. It can be served with or without sweetener, either hot or iced, and with fruit juice or milk.
- Yerba mate contains minerals, caffeine, antioxidants, and other nutrients that may offer health benefits. Traditionally, yerba mate has been used to help reduce mental and physical fatigue. More recently, yerba mate has been used to increase urination, treat headaches, and promote weight loss. However, scientific evidence is lacking. Some studies suggest that yerba mate may reduce blood sugar levels in people who have type 2 diabetes.
- Some studies suggest that drinking large amounts of yerba mate may increase the risk of some cancers, including oral, renal, and bladder. Also, the caffeine content of yerba mate may cause interactions with various prescription medications or herbal products.
