Lobelia inflata

Lobelia is a very strong herb historically used for respiratory spasm and chest tightness sensations—but it is also easy to overdo and can cause intense nausea and other adverse effects. This is not a beginner herb and not a casual DIY tea. If included at all, it should be framed as practitioner-guided and high-caution.
