Urinary tract infections (UTIs). A specific oral combination of
dandelion root and uva ursi leaf extracts seems to help reduce
the recurrence rate of UTIs in women.(3) In this
combination uva ursi is used for its antibacterial properties and
dandelion is used to increase urination.
Dandelion root contains quercetin, luteolin,
p-hydroxyphenylacetic acid, germacranolide acids, chlorogenic
acid, chicoric acid, and monocaffeyltartaric acid. In addition it
has a high potassium content. The roots contain caffeic acid,
taraxacoside, taraxasterol, and large amounts of the
Dandelion root promotes bile production and bile flow and urinary
flow. It is anti-inflammatory, anti-oxidative, analgesic,
anti-hyperglycemic, anti-coagulatory and has prebiotic effects.
Based on a small study using an alcohol extract of dandelion leaf
in human volunteers, this herb elicits a significant diuretic
effect in humans.(5
Emerging evidence suggests that dandelion and its constituents
have antioxidant and anti-inflammatory activities that result in
diverse biological effects.(6,7,13)
Animal studies show that dandelion has effects on detoxifying
enzymes in the liver.(9)
Preliminary evidence indicates a beneficial effect on
cardiovascular risk factors mediated by oxidative stress,
inflammation, and cholesterol profile. (13)
Dandelion root contains high concentrations of inulin.
Oligofructans, such as inulin, are used as food sources by
beneficial intestinal bacteria. Dandelion root enhances the
growth of bifidobacteria and may be useful as a
Dandelion extracts were effective for facilitating the
gastrointestinal motility in animal studies.(12)
Anti-cancer effects on melanoma, breast and prostate cancer cells
have been demonstrated. (10,11)
