Lobelia is one of the most useful systemic relaxants available to us. It has a general depressant action on the central and autonomic nervous system and on neuro-muscular action. It may be used in many conditions in combination with other herbs to further their effectiveness if relaxation is needed. Its primary specific use is in bronchial asthma and bronchitis for which it is wonderful. An analysis of the action of the alkaloids present reveals apparently paradoxical effects. Lobeline is a powerful respiratory stimulant, while isolobelanine is an emetic and respiratory relaxant, which will stimulate catarrhal secretion and expectoration while relaxing the muscles of the respiratory system. The overall action is a truly holistic combination of stimulation and relaxation! Do not take in excess because Lobelia has dangerous side effects when taken in high doses!
