I keep a bottle of Absorbine Veterinary Liniment on hand for rashes, cuts, any skin problems. Absinthium oil is an ingredient.
Absorbine Jr. is great. It has two different anaesthetic ingredients - good for pain, good for bug bites. It actually keeps bugs away too.
It’s an old company with an interesting history.
