Everybody knows the dandelion plant. Taraxacum dens leonis is its botanical name. The leaves are liked by some people as a kind of "greens" for the table. The root has long been known, when chewed or drunk in the form of a tea, to act upon the kidneys, increasing the flow of water. Besides this diuretic action, it appears also to aid in relieving torpor of the liver.

Extract of taraxacum is the most convenient preparation. In ten- or twenty-grain does it may be taken by those who have symptoms threatening bilious colic, or who, from nausea, dizziness, a bitter taste, and yellow eyes and tongue, appear to suffer from imperfect removal of bile from the system. It is thus a mild and safe assistant to, or perhaps substitute for, blue mass.
