Lobelia Powder (Lobelia inflata)

Ground aerial parts of Lobelia inflata, the species historically called "Indian Tobacco" by colonial settlers who observed Native American use of the plant. Lobelia has a complicated history in Western herbalism: championed by Samuel Thomson in the 1800s as a key herb, criticized by other practitioners, and known to be a strong emetic in larger doses.

What is Lobelia?

Lobelia inflata is an annual plant native to eastern North America with small pale blue-purple flowers. Native peoples used the plant medicinally and as a ceremonial smoke. In the 19th century, the herbalist Samuel Thomson built an entire system of Western herbalism around lobelia as a central herb. Lobeline, the primary alkaloid, structurally resembles nicotine and has been studied as a potential smoking cessation aid.

Important Safety Information

Lobelia is a strong emetic at higher doses (one common name is "Puke Weed"). Use only in very small amounts; signs of excess include nausea, vomiting, dizziness, and reduced respiration. Not recommended for pregnant women, individuals with hypertension, or anyone with cardiovascular concerns. Consult a healthcare practitioner before use.

How to Use Lobelia

Typical Western herbal use is in very small amounts: a small pinch (50-100 mg) of powder, or 5-10 drops of tincture, as a starting point. Lobelia is most often used in formulations rather than as a single herb.
