I just recently cured my dog's aural hematoma after only one week using:
1. turmeric in food (light sprinkle, ~1/8 tsp)
2. Chinese Herb Yunnan Baiyao, made into a paste and applied topically 2x/day (but can also be given internally - I just didn't have the time to figure out how best to do so because it is BITTER gross nasty)
3. Arnica tablets 30c, 2 crushed tablets 4x/day on day 1, then cut back to only three times a day.
Hope this helps!
