Action, Medical Uses, and Dosage
History - This well-known plant is a native of southern or Mediterranean Europe , and is cultivated in this country. The flowers, or heads, as they are commonly called, appear in August and September, and are the parts used; the succulent receptacle and part of the calyx-leaflets are the edible portions. In their young stage, the heads, prepared with vinegar, salt, etc., are much valued by some persons. The corollas are used for coagulating milk. The juice of the leaves is amarous. This plant must not be confounded with the Helianthus tuberosus or Jerusalem artichoke, a species of sunflower, the tuberous roots of which are sometimes used as a substitute for potatoes, and as feed for hogs.
Action, Medical Uses, and Dosage - Diuretic and alterative. Reputed very beneficial in dropsies, and has been efficient in rheumatism, gout, jaundice, tic-douloureux, etc. The recent leaves only should be used in the form of an extract, or alcoholic solution. Dose of the tincture, 30 to 60 drops, repeated 3 times a day; of the extract, 3 to 6 grains (Dr. Badely, in London Lancet, 1843, p. 556).
