Clinical Safety & Potency Guidance
Raw Aconitum napellus is extremely toxic due to aconitine alkaloids (causing fatal arrhythmias and respiratory paralysis). Raw plant tinctures are strictly restricted; homeopathic preparations must be potentized (30C/200C). Immediate emergency evaluation is mandatory for severe dyspnea, chest pain, or anaphylaxis.
