Uses based on scientific evidence
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare professional.
Non-human research suggests that dandelion root may possess anti-inflammatory properties. There is a lack of well-designed human studies in this area. Additional research is needed.
Several laboratory studies report antioxidant properties of dandelion flower extract. However, this research is preliminary and data in humans is lacking. Further research is warranted in this area.
Limited animal research exists on the effects of dandelion on tumor growth, but the data is inconclusive. Additional high-quality human studies are needed in this area.
Colitis (colon inflammation)
There is a report that a combination herbal preparation containing dandelion improved chronic pain associated with colitis. The effects of dandelion alone are unknown. Additional research is needed before a conclusion can be made.
There is limited research on the effects of dandelion on blood sugar levels. One study reported decreases in glucose levels in non-human studies. Additional study is needed in this area.
Diuretic (increased urine flow)
Dandelion leaves have traditionally been used to increase urine production and excretion. There is a lack of reliable human research in this area. Dandelion extract has been reported to increase fluid excretion and urination frequency. Further research in humans is needed.
One study reported improved liver function in people with hepatitis B after taking a combination product with dandelion root. The effects of dandelion alone are unknown. Additional research is needed on this topic.
Early research suggests dandelion with penicillin is more effective than sodium penicillin alone for sore throat. Given the limited evidence, conclusions on the effects of dandelion alone are unclear. Additional studies are warranted.
