Lobelia inflata L. | |
Lobelia inflata (Indian tobacco, 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.[2]
Growth
It is an annual or biennial herbaceous plant growing to 15–100 centimetres (5.9–39.4 in) tall, with stems covered in tiny hairs. Its leaves are usually about 8 centimetres (3.1 in) long, and are ovate and toothed. It has violet flowers that are tinted yellow on the inside, and usually appear in mid-summer and continue to bloom into fall.[3]
Cultivation and uses
Lobelia inflata has a long use as an entheogenic and emetic substance. The plant was widely used by the Penobscots and was widely used in the New England even before the time of Samuel Thomson, who was credited as discovering it. Indian Tobacco, also known as "pukeweed", is still used today. It can be used fresh, or dry.
It is also said that plant material is burned as a natural bug repellent to keep away insects such as mosquitoes.
It contains lobeline.
Appearance
from its microscopical examination: anomocytic stomata, sclerenchymatous idioblast, very long non-glandular hair with enlarged base and warty cuticle, spherical pollengrain
Propagation
Propagation is usually accomplished by cuttings or seed. Seeds are sown in containers in mid spring or mid fall. The seeds take about 2 weeks to germinate.
Traditional use
Native Americans used lobelia to treat respiratory and muscle disorders, and as a purgative. The species used most commonly in modern herbalism is Lobelia inflata (Indian tobacco).[4] However, there are adverse effects that limit the use of lobelia.[5]
