Dandelion (Taraxacum officinale)

Dandelion: Medical Uses Dandelion root is used most often for liver disease and to increase bile flow. The root is also used as a coffee substitute. The leaves are used primarily for their diuretic effect and for adolescent acne. Historical Uses Dandelion first appeared in the 10th century in Arabian medicine and has been used as a diuretic, a treatment for anemia, a blood tonic, a mild laxative, and an appetite stimulant. Europeans used dandelion to treat diabetes. It is reported that dandelion is more nutritious than spinach. It may have antiviral properties that help prevent herpes. It also has been used to treat premenstrual syndrome and hepatitis. It is also called lion’s tooth and wild endive. Growth Dandelions grow in lawns and fields throughout the spring and summer in the northern hemisphere and are usually considered weeds. The plant has “lion-toothed” leaves and a bright yellow upright flower.

Dandelion: Uses. Dosage. Interactions. Pregnancy Use. Practice Points

Clinical Use The therapeutic effectiveness of dandelion has not been significantly investigated under clinical trial conditions, so evidence is derived from traditional, in vitro and animal studies. DIURETIC Dandelion has a long history of use as a diuretic in well-established systems of traditional medicines; however, the scientific and clinical evidence to support this use is limited to animal studies. The high potassium content of dandelion is considered to be partly responsible for any diuretic activity. A double-blind randomised study of 57 women with recurrent cystitis found that a commercial preparation known as Uva-E (a combination of Arctostaphylos leaves and dandelion root) significantly reduced the frequency of recurrence of cystitis compared with placebo. At the end of 12 months, none of the patients taking Uva-E had had a recurrence of cystitis, compared with 23% recurrence in the control group (P < 0.05). The role of dandelion in achieving this result is unknown; however, the researchers suggested that its diuretic effect was likely to have contributed to the positive results. LIVER TONIC Dandelion has a long history of use as a liver tonic; however, the scientific and clinical evidence to support Read more […]
