Rating (out of 5): 1

Lobelia (Lobelia inflata), also known as Indian tobacco, has a long history of use in Native American and Western herbal medicine. Traditionally, lobelia was used for respiratory complaints, as an expectorant, and to induce vomiting in cases of poisoning. In the context of the lymphatic system, some herbalists have included lobelia in formulas intended to "stimulate lymphatic drainage" or "move stagnation," but this is based almost entirely on traditional energetic models of herbalism rather than physiological evidence. There are no well-controlled scientific studies demonstrating that lobelia directly affects lymphatic function or supports lymphatic health. The plant contains alkaloids, notably lobeline, which have been studied for their effects on the nervous and respiratory systems, but not on the lymphatic system. Most references to lobelia’s use for lymphatic health appear in herbal compendia and practitioner traditions rather than in biomedical literature. Given the lack of rigorous scientific validation and the reliance on traditional use, the evidence supporting lobelia for the lymphatic system is weak. Lobelia can also be toxic in higher doses. Therefore, its use for this purpose should be approached with caution and is not widely endorsed in evidence-based practice.
