Sorry to hear about the injury - hope Milo will heal well and quickly so .
I think , I never used this particular medicine ( might have , but am not so very knwoledgable about chinese meds ) - the ingredients sound fine ! On my dogs , who had some toe injuries over the years , I would use metacam for the 1rst 3-7 or so days in case they are really painful , otherwise I 'd rather not ;I think it damages the kidneys in long time use ( or was it the liver ? ) , also , to feel a little bit of pain keeps mine quieter ! helps the healing process... - and I would use heparin ointment on the toe /swelling - does the same , increase circulation/promote healing basically . In addition I would give arnica ( in various potencies ) and , most likely symphytum - as liquid on the skin or /and internally. Most of all , time to heal is important - leash walks , perhaps a good dogshoe ( with a harder/leather sole ( like the muttlukks available here ) to keep the toe a bit more even during a walk .
