Lobelia Benefits

Lobelia inflata is an herb that is used to treat asthma, allergies, whooping cough, congestion, and bronchitis. In the past, it was also useful for tobacco withdrawal as an herbal remedy to quit smoking. It is found in the southeastern part of Canada from Nova Scotia to Southeast Ontario and British Columbia. It is also present in the eastern half of the United States (excluding the state of Florida).

Lobelia is a fragile flower described as light bluish to violet in color with a touch of yellow that can grow to a height of about three feet. It is a very popular garden plant that also has pale green or yellowish leaves. It is categorized as an annual or biennial plant meaning that it reseeds every year or two. The stem is smooth towards the top and hairy and rough towards its bottom. The flowers are asymmetrical and bisexual. The main parts used of the Lobelia plant are the flowering parts and the seeds. The seeds are the most potent because they contain lobeline, a piperidine alkaloid.

Named after Matthias de Lobel, a 17th century botanist, Lobelia is known as Indian Tobacco because it contains lobeline. Lobeline is believed to have a chemical make up similar to nicotine and was therefore used as an alternative to tobacco. In the 19th century, Lobelia was also used as a medicinal herb to induce vomiting, thus removing harmful poisons from the body.

The name Indian Tobacco was assigned because the Aboriginal people smoked dried leaves of the plant. Historically, the Aboriginal people were very creative and efficient in using the Lobelia plant for medicinal purposes. The Iroquois used the root to treat leg sores, venereal diseases and ulcers. The Cherokees used a poultice of the root for body aches. They also used the plant for boils, sores, bites and stings. Considered a plant to cure asthma, phthisic (lung disease), croup and a sore throat, it was also used to discourage the presence of gnats. The Crows made use of it in religious ceremonies.


Lobelia is considered to be a toxic herb because of its lobeline affiliation. It is important to begin with lower dosages and increase the dosage over a period of time.It is also imperative that you never surpass a dosage of 20 mg per day. If you consume a dosage higher than 500 mg, it could be fatal. Lobelia can be taken in a few different forms. It can be given as a vinegar tincture or a regular tincture, as a fluid extract, or as a dried herb for teas or in capsules. It is preferred that the dried herb be mixed in eight ounces of water with other herbs but not necessarily recommended as the best way of consuming it due to its pungent taste.

Lobelia Herb Notes / Side Effects

This herb is toxic at low doses and in some countries the sale of Lobelia is limited. In the past Lobeline was used in anti-smoking products as a deterrent for those with a smoking addiction. However, the sale of smoking products that contained lobeline was prohibited by the Food and Drug Administration in 1993 because it was not helpful to those who were addicted to smoking. Lobelia also contains various alkaloids other than lobeline which include lobelacrin, a bitter glycoside, lobelianin, a pungent oil and resin, acid, fats and gum. It also has 14 pyridine alkaloids. Therefore it is always best to consult your health care physician for proper dosage and use.

There are side effects to be aware of when using Lobelia. Some side affects include vomiting, convulsions, hypothermia, dizziness, dry mouth, coma, or death. Weakness, difficulty breathing, heartburn, collapsing or a weak pulse are signs of poisoning. If you have been diagnosed with heart disease, tobacco sensitivity, seizure disorder, paralysis, shortness of breath, high blood pressure, or are recovering from shock, you should not take this herb. It is also not recommended for women that are pregnant or breastfeeding.

To EUB,, It may be true that if you do not have seizures of ANY TYPE, Lobelia can maybe not be a popular herb for any person to use. I would not know what that kind of life could be like even as I am now 10 months without any seizures, and I never had to use Lobelia for that purpose when a seizure can be starting. So having Grand Mal seizures is humorous to you ? Really ? That's not worth a comment.

The dosing info provided on this page (20 mg maximum) is questionable inasmuch as many formulas on the market begin at 425mg/capsule with instructions to take one to two capsules.

I have found lobelia to be an excellent smooth muscle relaxer. I have used it to treat bilary colic and to help pass kidney stones. I have found it to be as effective as phenegren for calming the stomach during vomiting caused by a stomach virus. This is my go to remedy when one continues to vomit after all the stomach's contents have emptied. When even one's swallowed saliva will not stay down, a few drops of lobelia tincture in half a cup of water will stop it. I tell the patient that they may vomit it up, but it is usually the last time that they will vomit during that illness.

Yes Lobelia works. Lobelia saved me fro going into a grand mal seizure over 12 years ago. Lobelia shortens the time span that I can be in a grand mal seizure that would happen as I only take the Lobelia when I feel a grand mal is about to happen. Who are those people who says thet Lobelia causes seizures ?  They are not living in the same world I am in as they must be FDA doctors and neurologist, or some other brain specialist. Lobelia has never caused my brain to fry and go into any type of seizure. Get a life.
