Historically, Native Americans smoked lobelia as a treatment for asthma. In the 19th century, American physicians prescribed lobelia to induce vomiting in order remove toxins from the body. Because of this, it earned the name "puke weed." Today, lobelia is sometimes suggested to help clear mucus from the respiratory tract, including the throat, lungs, and bronchial tubes. Although few studies have evaluated the safety and effectiveness of lobelia, some herbalists today use lobelia as part of a comprehensive treatment plan for asthma.Scientists think an active ingredient in the lobelia plant, lobeline, has similar effects to nicotine. For this reason, lobeline was once used as a nicotine substitute in many antismoking products and preparations designed to break the smoking habit. In 1993, the U.S. Food and Drug Administration (FDA) prohibited the sale of smoking products containing lobeline. The FDA reported that such products were not effective in helping people quit or reduce smoking.Researchers now think that lobeline may actually reduce the effects of nicotine in the body, particularly the release of dopamine. Dopamine is a brain chemical that plays a number of important roles in the brain. It is also involved in drug addiction, so researchers think that lobeline may have some potential in treating addiction. So far, however, there have been no studies to determine whether lobeline is effective.Lobelia is a potentially toxic herb. It can be safely used in small doses (particularly homeopathic doses), but moderate-to-large doses may cause side effects ranging from dry mouth and nausea to convulsions and even coma (see "Precautions" section). You should use lobelia only under the supervision of your health care provider. Plant DescriptionLobelia is an attractive annual or sometimes biennial (reseeding every year or 2) herb that grows to a height of 3 feet. Its upright, hairy stem is angular, branching at the top, usually green with a tinge of violet. The pale green or yellowish leaves have a sharp taste and a slightly irritating odor. The sparse flowers are pale violet blue outside and pale yellow inside.Parts UsedThe above-ground portions of the lobelia plant (namely the leaves and seeds) are used for medicinal purposes.Medicinal Uses and IndicationsFew studies have examined at the effect of lobelia in either animals or people. It is sometimes suggested (usually in combination with other herbs) for the treatment of the following respiratory problems:Asthma Bronchitis Cough In homeopathy, lobelia is also used alone or with other products for smoking cessation, muscle relaxation, nausea, vomiting, skin infections (bites, bruises, poison ivy, and ringworm), and various respiratory illnesses.Available FormsLobelia is available in liquid extracts, tinctures, and as a dried herb in capsules and for teas. It may also be put on the skin in the form of ointments, lotions, and plastics.How to Take ItBegin with low dosages and increase gradually, depending on response. Remember that even moderate doses can be toxic; herbal Lobelia should only be taken under the guidance of a knowledgeable herbal prescriber.PediatricThere are no studies evaluating whether it is safe to give lobelia to a child. Avoid use in children unless under the supervision of your child's health care provider.AdultLobelia comes in dried form to be used as a tea, liquid extract, tincture, and even vinegar tincture. Speak to a knowledgeable provider to find the right dose for you.PrecautionsThe use of herbs is a time-honored approach to strengthening the body and treating disease. Herbs, however, contain substances that can trigger side effects and interact with other herbs, supplements, or medications. For these reasons, you should take herbs with care, under the supervision of a health care provider.Lobelia is considered a potentially toxic herb. It can cause serious side effects, such as profuse sweating, nausea, vomiting, diarrhea, tremors, rapid heartbeat, mental confusion, convulsions, hypothermia, coma, and possibly even death. Check with your provider to determine the right dose for you, and do not exceed your provider's recommended dose.People with high blood pressure, heart disease, liver disease, kidney disease, tobacco sensitivity, paralysis, seizure disorder, and shortness of breath, and those recovering from shock should not take lobelia.Lobelia can irritate the GI tract. Lobelia may make symptoms worse for people with ulcers, Chron disease, inflammatory bowel disease (IBD), or intestinal infections.Pregnant and breastfeeding women should also avoid this herb.Possible InteractionsFew studies have looked at the effects of lobelia, so scientists are not clear about which medications might interact with this herb. Based on some of the chemicals contained in lobelia, use caution with the following medications:Psychiatric medications: Including antidepressants, Lithium, anti-anxiety agents, and stimulants (such as those taken for attention deficit hyperactivity disorder).Nicotine substitutes: Such as nicotine patches or gum.Chantix (varenicline): Chantix, a stop smoking medication, also affects dopamine levels in the brain.Tobacco: Including cigarettes and smokeless tobacco.Supporting ResearchAuerbach, P.
