Because it was such a bad burn, I didn't dilute it at all. I made him sit with his hand in a bowl....full strength. Expensive, but I think worth it.
We drink it everyday - one ounce in a gallon of distilled water. Don't know if there have been in health related effects, but it is safe, so we decided, what the heck!
It helped my cats, who were very aggressive towards each other. It seems to have calmed them down a bit.
