The root, fresh and dried, the young tops. All parts of the plant contain a somewhat bitter, milky juice (latex), but the juice of the root being still more powerful is the part of the plant most used for medicinal purposes.

 

 The chief constituents of Dandelion root are Taraxacin, acrystalline, bitter substance, of which the yield varies in roots collected at different seasons, and Taraxacerin, an acrid resin, with Inulin (a sort of sugar which replaces starch in many of the Dandelion family, Compositae), gluten, gum and potash. The root contains no starch, but early in the year contains much uncrystallizable sugar and laevulin, which differs from Inulin in being soluble in cold water. This diminishes in quantity during the summer and becomes Inulin in the autumn. The root may contain as much as 24 per cent. In the fresh root, the Inulin is present in the cell-sap, but in the dry root it occurs as an amorphodus, transparent solid, which is only slightly soluble in cold water, but soluble in hot water.

 

 

Diuretic, tonic and slightly aperient. It is a general stimulant to the system, but especially to the urinary organs, and is chiefly used in kidney and liver disorders.

Dandelion is not only official but is used in many patent medicines. Not being poisonous, quite big doses of its preparations may be taken. Its beneficial action is best obtained when combined with other agents.
