Taraxacum Officinale
The root, leaves as well as Dandelion flowers are used medicinally. The flowers can be added to salads, or made into a nourishing tea. The leaves benefit the kidneys, and are also rich in Potassium and other minerals while acting as a diuretic, reducing hypertension.
Dandelion root would make an excellent addition to our daily regimen. It is a bitter tonic, stimulating the production of bile and digestive acids for better assimilation of nutrients, as well as elimination of toxins from the body.
Fortifying the Liver, Kidneys and the Gall bladder, dandelion does wonders to relieve the body of congestion, indigestion or constipation caused by rich foods and alcohol.
Rich in Sodium, Potassium, Iron, Manganese and many other trace minerals and vitamins, Dandelion root supports the immune system to eliminate free radicals, reducing high blood pressure, arteriosclerosis and lowering cholesterol levels. Dandelion root is also rich in inulin, which is a prebiotic.
I prefer the Tincture of Dandelion root (Alcohol extract) to the tea, since two of its medicinal constituents, Taraxasterol and Taraxerol are insoluble in water.
If you are trying to cut down on your caffeine, drink Dandelion Root tea instead. The bitter tasting Dandelion root tea is a healthy alternative to Coffee.
