Lobelia, Lobelia inflata, is a powerful antispasmodic herb. It dilates the bronchial passage to ease asthma attacks and eases pain caused by tension. It helps to clear lymphatic congestion and can be applied topically to insect bites and stings.
The FDA considers lobelia to be poisonous, and many sources claim it will cause convulsions, coma, and death. These are potential effects of its principal alkaloid lobeline, but there is no record of the whole herb causing these problems in anyone. Lobelia is an emetic and makes you throw up if you take too much. Lobelia can produce severe symptoms (nausea, profuse, sweating, vomiting, and deep relaxation), but these symptoms typically pass quickly and the person feels better afterward. However, because of these effects, lobelia is not recommended for the weak, debilitated persons or persons who are deeply relaxed. Lobelia is not recommended for long-term use and should be used cautiously during pregnancy. To avoid unpleasant effects such as nausea and vomiting, use small, repeated doses instead of large, infrequent doses, or use it as part of a formula.
This can be used as an infusion, tincture, glycerite, capsule, or topical use.
