Dandelion is usually considered an aggravating lawn weed, but it has long been used in many traditional medical systems, such as Native American and Chinese, to manage a broad range of health problems, including liver and kidney diseases. Dandelion continues to be used today for many of the same conditions, although scientific studies have not provided convincing evidence to support using dandelion for any health problem. Consult with your doctor before using dandelion medicinally.
How It Works
Dandelion contains substances called bitter principles that are thought to be the active chemicals responsible for the primary health effects of dandelion root. These chemicals are unique to dandelion. The bitter compounds in the root work to enhance digestion, and they cause a mild laxative effect. These chemicals also promote the manufacture of bile in the gallbladder and increase bile flow from the liver, which possibly enhances fat and cholesterol metabolism in the body. Dandelion root also consists of approximately 40 percent inulin, which is a substance that may increase insulin production and help to control blood glucose levels.
Preparations and Dosage
Dandelion root is available as standardized powdered root extract and root tincture. The powdered root is typically used in doses of 1/2 to 1 teaspoon, or 3 to 5 g, taken three times daily as a general liver tonic and to stimulate digestion. Dandelion tincture in doses of 1 to 2 teaspoons, or 5 to 10 ml taken three times daily, may also be used. The alcohol-based tincture is preferred because the bitter principles dissolve better in alcohol.
Medicinal Uses
Dandelion roots are mainly used as an appetite stimulant, digestive aid, and for liver and gallbladder function. According to the National Institutes of Health, or NIH, dandelion root has also been used in combination with leaf extracts of another herb called uva ursi for helping to preventing urinary tract infections in women. In this combination, uva ursi is used for its potential ability to kill bacteria, and dandelion is used to enhance urine flow.
Considerations
According to the NIH, dandelion is considered as generally safe when taken in food amounts and as likely safe when taken in medicinal amounts. You should not take dandelion if you have gallstones, gallbladder disease, or blockage in your bile duct because dandelion may increase bile flow from your gallbladder. You should also avoid dandelion if you are pregnant or breast-feeding. If you have diabetes, check your blood sugar levels closely because dandelion can lower blood sugar levels.
