Fresh Dandelion Root Side Effects

Dandelion root traditionally has been used to treat ailments including gall-bladder and kidney conditions, joint problems and liver issues. In some cultures, it has been used as a blood purifier. The use of dandelion root is based on tradition and not on scientific studies confirming its effectiveness. Medical observation has observed some side effects, however, from treatments involving dandelion root.

Bitter Principles

• Chemicals that occur naturally in dandelion root, including sesquiterpene lactones, promote digestion, act as a laxative and increase bile production and bile flow from the liver. These chemicals, also referred to as "bitter principles" in literature about herbal medicine, also cause dandelion roots' side effects.

Gallstones

• Dandelion root can cause problems for people who are already suffering from gallstones. Gallstones are associated with bile that contains an excessive amount of cholesterol. Dandelion root increases bile production. The use of dandelion root by someone who already has gallstones should be supervised carefully by a health care provider, according to the online health library of the University of California, San Diego Medical Center.

Obstructed Bile Ducts

• Dandelion root is not recommended for people who have obstructed bile ducts, as dandelion root increases bile production, according to the University of California, San Diego Medical Center.

Overproduction of Stomach Acid

• Dandelion root stimulates the stomach to produce more stomach acid, according to the University of California, San Diego Medical Center. This can lead to an overproduction of stomach acid. This is particularly problematic if a person has an ulcer or gastritis.

Allergic Reaction

• Dandelion root contains a fiber called inulin. Inulin is a common food ingredient. However, there has been at least one documented case of a serious allergic reaction to inulin, according to the University of California, San Diego Medical Center.

Drug Interactions

• Dandelion root is known to have adverse reactions with some drugs, including both the loop, thiazide and spironolactone classes of diuretics. Dandelion root may also decrease the effectiveness of ciprofloxacin, which is an antibiotic.
