A VERY beautiful wild plant growing in corn fields, with large bluish leaves, and full of flowers like marigolds. It is two feet high; the stalks are numerous, round, stiff, tolerably upright, and branched; the leaves stand irregularly, and are long, very broad, and of a bluish green; they are smallest towards the base, and larger at the end, and they are deeply cut in at the sides. The flowers are as broad as half a crown, and of a very beautiful yellow; they have a cluster of threads in the middle. The root is fibrous.
The flowers, fresh gathered and just opened, contain the greatest virtue. They are good against all obstructions, and work by urine. An infusion of them, given in the quantity of half a pint warm, three times a day, has been known to cure a jaundice, without any other medicine; the dried herb has the same virtue, but in a less degree.
