What is lobelia?

Lobelia is a group of flowering plants native to North America.

Hundreds of species exist, including Lobelia inflata, which has tall green stems, long leaves, and tiny violet flowers.

Native Americans in the New England region of the United States used Lobelia inflata for medicinal and ceremonial purposes for centuries. It was smoked and burned to induce vomiting or treat asthma and muscular disorders.

This variety of applications earned the plant the nicknames Indian tobacco and puke weed.

Lobelia inflata continues to be used for medical purposes today. Studies indicate that lobeline, its main active compound, may protect against depression, help treat drug addiction, and improve memory and concentration.

Lobelia is available loose and dried for making into tea, as well as in capsules, tablets, and liquid extracts. The flowers, leaves, and seeds are used in various preparations.
