Nat. ord., Lobeliaceae.

Synonym. - Lobelia Syphilitica.

Blue Lobelia. Great Lobelia.

A plant with a somewhat hairy stem, from 1 to 3 feet high, indigenous to North America; thought at one time to possess specific powers in the treatment of syphilis, as its name implies, and used by the Indians for that purpose, but found valueless; it has, however, been found serviceable in other complaints.

Characters. - The flowers are generally of a light blue colour, occasionally white. The leaves are thin, ovate, acute at both ends, 2 to 6 inches long, irregularly serrate.

A notice will be found in Hale's New Remedies, where a tincture is directed to be made from the leaves; in allopathic practice the root is the part used.
