This very common annual grows from one to three feet high along roadsides and in neglected fields, and blossoms from July to November. All parts of this Lobelia are medicinal, and Shakers and herb dealers prepare and sell it in oblong, compressed cakes. The plant, however, is considered to be somewhat poisonous, and if the leaves or capsules are chewed for a short time, they produce a sensation of giddiness, then headache, and finally nausea and vomiting. If swallowed it produces more serious results, and has been known to have caused death. The Indians are said to have used the foliage as tobacco. In more modern practice it has been employed as a remedy in various affections of the throat, including acute attacks of catarrh, croup and asthma. The upright stalk is leafy, often slightly hairy, rather stout and branching. The thin alternating leaves are oval or oblong in shape, with short-pointed ends and toothed margins. The upper ones clasp the stalk and become smaller and narrower as they approach the top. The flowers are quite small, light blue in colour, and are set on tiny stems, generally in the axil of a leaflet. They are formed much the same as those of the Spiked Lobelia, and are scattered along the stalk, forming loose, terminal spikes. This species is easily distinguished by the prominent inflated seed cases which succeed the flowers. The Indian Tobacco is found in dry, open soils from Georgia, Nebraska and Arkansas, and far into Canada.
