Dandelion root refers to the underground part of the dandelion plant, which is commonly used as a natural remedy for various health conditions. It contains several active compounds such as taraxasterols, flavonoids and inulin that are believed to have medicinal properties. Dandelion root has been traditionally used to treat liver problems, digestive issues, kidney disorders, and even cancer. Some people also use it as a diuretic or to improve their overall well-being. However, the effectiveness of dandelion root for these conditions is still under scientific investigation, and more research is needed to fully understand its potential health benefits.
