Lobelia Inflata is a plant. The above ground parts are used to make medicine.
Lobelia Inflata helps with smoking cessation. Most research suggests that taking lobeline, a chemical found in lobelia, does not help people quit smoking cigarettes or chewing tobacco.
Lobelia is used for breathing problems including asthma, bronchitis, whooping cough, and shortness of breath (apnea) in newborn infants. Some people take lobelia as a sedative to help them relax. Other people use it to increase sweating.
Lobelia is applied to the skin for muscle pain, joint lumps associated with rheumatoid arthritis (rheumatic nodules), bruises, sprains, insect bites, poison ivy, and ringworm.
In manufacturing, lobelia is used in cough preparations and counterirritant products. Some stop-smoking products around the world include lobelia as an ingredient. But since 1993, manufacturers have not been allowed to include lobelia in stop-smoking products sold in the U.S. That’s when research found that lobelia doesn’t make stop-smoking products any more effective.
Lobelia is considered LIKELY UNSAFE for most people when taken by mouth. Side effects include nausea, vomiting, diarrhea, cough, dizziness, tremors, and more serious effects.
Overdose may cause many serious toxic effects including sweating, convulsions, fast heartbeat, very low blood pressure, collapse, coma, and possibly death. Taking 0.6-1 gram of the leaf is said to be toxic, and 4 grams may be fatal.
Not enough is known about the safety of applying lobelia to the skin
Lithium interacts with LOBELIA
Lobelia might have an effect like a water pill or “diuretic.” Taking lobelia might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.
