Arnica Montana flower tincture. Perhaps the ultimate trauma remedy. Non-homeopathic arnica like this tincture is for external use only; for soothing trauma of all kinds, and for reducing bruising, swelling, and pain both acute and chronic. Suggested uses: May be dropped into a birth tub, bath water, sitz bath, or poultice. A drop of tincture can be mixed with oil in the hands and massaged onto sprains or applied to bruises or shallow wounds. Only homeopathic preparations (not tinctures) of arnica are used internally, for the same purposes.
