MEDICINAL ACTION AND USES
Expectorant, anti-asthmatic and increase sweating. It should not be employed as an emetic. It is sometimes given in convulsive and inflammatory disorders such as epilepsy, tetanus, diphtheria, and tonsilitis. A homemade cough syrup can be created by combining tea made from lobelia and other cough suppressing herbs, such as mullein and wild cherry bark, with honey. Lobelia is almost never used alone as a treatment for any condition, due to its strength, and must be combined with other herbs.
There is also a difference of opinion with regard to its narcotic properties. Where relaxation of the system is required, as, for instance, to subdue spasm, Lobelia is invaluable. Relaxation can be counteracted by the stimulating and tonic infusion of capsicum. It may be used as an enema.
Lobelia is considered to be a toxic herb because of its lobeline affiliation. It is important, to begin with, low dosages and increases 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 is very similar to nicotine and should not be used internally by children, pregnant women, or sufferers of heart disease. It should not be taken by anyone in large amounts or for long periods of time. Taking more than 50 mg per day can lead to suppressed breathing, decreased blood pressure, or even coma. The herb should only be administered by a medical professional, qualified in herbal or natural medicine (Botanicals.com).
