Lobelia inflata, also known as Indian tobacco or puke weed, is a species of Lobelia native to eastern North America, from southeastern Canada (Nova Scotia to southeast Ontario) south through the eastern United States to Alabama and west to Kansas.

[3] Lobelia inflata is an annual or biennial herbaceous plant growing to 15–100 cm (5.9–39.4 in) tall, with stems covered in tiny hairs.

It has violet colored flowers that are tinted yellow on the inside, and usually appear in mid-summer and continue to bloom into fall.

Lobelia inflata has a long use as a medicinal plant as an entheogenic, emetic, and skin or respiratory aid.

[7] Although it may be used medicinally,[9] consuming lobelia causes adverse effects, which may include sweating, nausea, vomiting, diarrhea, tremors, rapid heartbeat, mental confusion, convulsions, hypothermia, coma, or possibly death.
