Quick Reference Facts
"Sanguinaria is described in traditional materia medica for right-sided periodic headache rising from occiput over right eye, circumscribed red cheeks, and burning palms and soles."
Clinical Description
Sanguinaria Canadensis (Bloodroot) is a major right-sided cephalic, respiratory, and vasomotor botanical remedy proved by Dr. Bute, Dr. Hering, and Dr. Neidhard. In classical homeopathic texts, it is celebrated for its specific pathogenetic affinity for the right side of the head, right shoulder, respiratory mucous membranes, and vasomotor circulation. Key features recorded in materia medica include periodic American sick headaches (migraines) beginning in the morning in the occiput, spreading upwards over the vertex and settling definitively over the right eye and temple, circumscribed redness and burning heat of the cheeks, vasomotor flushes of heat during menopause with burning of palms and soles, right-sided subacute rheumatism of the shoulder and deltoid, and dry hacking cough with rust-colored or foul-smelling sputum.

- Menopausal vasomotor disturbances: sudden flashes of burning heat with burning heat in palms and soles (forcing uncovering of feet at night)

Therapeutic Affinities
Clinical Safety & Potency Guidance
Crude Bloodroot contains toxic benzylisoquinoline alkaloids (sanguinarine, chelerythrine) with severe corrosive and cardiotoxic properties; source-specific toxicology guidance is required. A homeopathic dilution label does not by itself guarantee composition, quality, safety, or effectiveness. Acute intracranial hemorrhage, hypertensive encephalopathy, acute lobar pneumonia with severe respiratory distress/cyanosis, or stroke requires immediate emergency hospital management; this traditional profile must not delay proven care.
