Consumer advice
If you're interested in dandelion root, buy a cheaper bulk powder or tea form from a grocery store or bulk supplier—the active compounds are the same. Don't expect dramatic liver detox or digestive miracles; traditional use doesn't equal clinical proof. If you have liver disease or take medications, consult a doctor first, as dandelion can interact with certain drugs and may worsen some conditions."
