Wild yarrow is a natural antibiotic, anti-fungal and anesthetic. Enjoy a hint of its woodsy scent in this bar. Includes yarrow essential oil. Why mill the soap? Because the yarrow is added to the milled soap AFTER the saponification process, so that the effectiveness of the yarrow is not affected.
I used this on my dear departed dog Bear, who suffered from hot spots on her skin. After trying everything, I started bathing her with yarrow soap, as well as treating the spots with yarrow cream, and voila! problem solved.
