Lobelia is a member of the bluebell family of flowering plants found in North America and Europe. Not surprisingly, then, the low-growing plant produces cascades of vibrant deep purple-blue flowers. Lobelia has a long history of use by Native Americans, who gave the plant many nicknames like Asthma Weed and Indian Tobacco, indicating the herb was once smoked. Other less attractive but descriptive alternate names for this herb include Vomitwort and Pukeweed. The dried leaf and powdered herb of lobelia are typically used to make tinctures and syrups, as well as infusions for use in topical ointments and salves.
