Dandelion

There is currently no reliable evidence available for the effectiveness of dandelion for the above uses.

When using dandelion as a diuretic it should be for occasional use only. When used for flushing of the urinary tract, indigestion, and loss of appetite, you should contact your healthcare provider if symptoms persist for more than 2 weeks.

Dandelion is generally well-tolerated. It may cause diarrhea, heartburn, and stomach discomfort. When applied to the skin, it may cause skin irritation.

There may be an interaction between dandelion and the following medications:

• blood-thinning medications (e.g., warfarin, clopidogrel, ASA)
• diabetes medications (e.g., metformin)
• lithium
• medications that are metabolized by the liver enzyme cytochrome P450 1A2 (e.g., amitriptyline, haloperidol, ondansetron, propranolol, theophylline, verapamil)
• potassium-sparing diuretics (e.g., spironolactone, amiloride, triamterene)
• quinolone antibiotics

Dandelion can slow blood clotting. When it is taken with other medications that affect your body's ability to clot blood, dandelion can increase the chance of bleeding and bruising. Stop taking dandelion at least 2 weeks before surgery.

Do not use dandelion without consulting your health care provider if you suffer from liver disease, gallbladder disease, or intestinal obstruction.

Do not use dandelion in doses of 10g per day or more of dried leaf or dried root if you:

• have heart disease
• have high blood pressure
• have low blood pressure
• have kidney disease
• have liver disease
• have diabetes
• have edema (swelling of the feet, face, and hands)
• are currently using a diuretic medication

You should avoid dandelion if you are allergic to it or to any plants in the Asteraceae/Compositae family, such as ragweed, chrysanthemums, marigolds, and daisies. People living with eczema are more likely to be sensitive to dandelion.

Before taking any new medications, including natural health products, speak to your physician, pharmacist, or other health care provider. Tell your health care provider about any natural health products you may be taking.
