In traditional Chinese and Native American medicine, dandelion root has long been used to treat stomach and liver conditions. Herbalists today believe that it can help treat many health problems including acne, eczema, high cholesterol, heartburn, gastrointestinal disorders, and diabetes. Dandelion root can act as a diuretic, causing you to produce more urine and helping to remove excess liquid from the body.
If you also take prescription diuretics or herbal supplements that make you urinate more, you could risk getting electrolyte imbalance. People who are allergic to dandelion root may experience rash, watery eyes, and other allergy symptoms.
