People use dandelion for conditions such as swelling (inflammation) of the tonsils (tonsillitis), infections of the kidney, bladder, or urethra (urinary tract infections or UTIs), and many others, but there is no good scientific evidence to support these uses.
How does it work ?
Uses & Effectiveness ?
Insufficient Evidence for
- Swelling (inflammation) of the tonsils (tonsillitis). Early research shows that people who have had their tonsils removed recover faster if they eat soup containing dandelion compared to those who eat soup without dandelion.
- Gas (flatulence).
- Heart failure.
- Indigestion (dyspepsia).
- Infections of the kidney, bladder, or urethra (urinary tract infections or UTIs).
- Joint pain.
- Other conditions.
Special Precautions and Warnings
Eczema: People with eczema seem to have a higher chance of having an allergic reaction to dandelion. If you have eczema, be sure to check with your healthcare provider before taking dandelion.
Bleeding disorders: Dandelion might slow blood clotting. In theory, taking dandelion might increase the risk for bruising and bleeding in people with bleeding disorders.
Ragweed allergy: People who are allergic to ragweed and related plants (daisies, chrysanthemums, marigolds) might be more likely to be allergic to dandelion. But conflicting data exists. If you have allergies, be sure to check with your healthcare provider before taking dandelion.
Surgery: Dandelion might slow blood clotting and lower blood sugar. It might cause extra bleeding and problems with low blood sugar during and after surgery. Stop using dandelion at least 2 weeks before a scheduled surgery.
Kidney failure: Dandelion might reduce how much oxalate is released through urine. In theory, this might increase the risk for complications in people with kidney problems.
Antibiotics (Quinolone antibiotics) interacts with DANDELION
Dandelion might decrease how much antibiotic the body absorbs. Taking dandelion along with antibiotics might decrease the effectiveness of some antibiotics.
Some antibiotics that might interact with dandelion include ciprofloxacin (Cipro), enoxacin (Penetrex), norfloxacin (Chibroxin, Noroxin), sparfloxacin (Zagam), trovafloxacin (Trovan), and grepafloxacin (Raxar).
Medications changed by the liver (Cytochrome P450 1A2 (CYP1A2) substrates) interacts with DANDELION
Some medications are changed and broken down by the liver.
Dandelion might decrease how quickly the liver breaks down some medications. Taking dandelion along with some medications that are broken down by the liver can increase the effects and side effects of some medications. Before taking dandelion, talk to your healthcare provider if you take any medications that are changed by the liver.
Some medications that are changed by the liver include amitriptyline (Elavil), haloperidol (Haldol), ondansetron (Zofran), propranolol (Inderal), theophylline (Theo-Dur, others), verapamil (Calan, Isoptin, others), and others.
Medications changed by the liver (Glucuronidated Drugs) interacts with DANDELION
The body breaks down some medications to get rid of them. The liver helps break down these medications. Dandelion might increase how quickly some medications are changed by the liver. This could decrease how well some of these medications work.
Some of these medications changed by the liver include acetaminophen, atorvastatin (Lipitor), diazepam (Valium), digoxin, entacapone (Comtan), estrogen, irinotecan (Camptosar), lamotrigine (Lamictal), lorazepam (Ativan), lovastatin (Mevacor), meprobamate, morphine, oxazepam (Serax), and others.
Water pills (Potassium-sparing diuretics) interacts with DANDELION
Dandelion contains significant amounts of potassium. Some "water pills" can also increase potassium levels in the body. Taking some "water pills" along with dandelion might cause too much potassium to be in the body.
Some "water pills" that increase potassium in the body include amiloride (Midamor), spironolactone (Aldactone), and triamterene (Dyrenium).
Lithium interacts with DANDELION
Dandelion might have an effect like a water pill or "diuretic." Taking dandelion might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.
