@Dr. Jeff I have a bottle of Heel Arnica PC. Do you suggest the boiron brand. The Heel brand has magnesium stearate in it which I don't like. I thought the old BHI Heel formulas did not have this excipient so that is why I was asking if you prefer the boiron brand.... I believe his injury on his front leg is better. However his sagging and weakness from the acupuncture on Aug 12th has not resolved. I guess I will address that in a different post because we went to the vet again last thursday. Thank you...!
