Lobelia is a small, low-growing plant in the bellflower family
that produces vibrant purple-blue flowers. The aerial parts of the plant
are traditionally used to combat inflammation of the skin and
respiratory disorders. The herb is also a component of herbal smoking
blends, as indicated by the common names Indian tobacco and asthma weed.
Internal use of lobelia is risky, however, as indicated by other common
names including pukeweed, emetic herb and gagweed. Although the herb is
not considered poisonous per se, it does exert potent emetic effects due
to the presence of the alkaloid lobeline.
