Absorbine Veterinary liniment?

Is the above liniment safe for humans? Several people have told me it
is the only med they are taking for lower back pain that gets rid
of the pain. They swear by it. It is a a topical Analgesic. Can be used for sore
muscles & joint pain relief. Sold by Walmart and American tractor supply. Its
cheap $12.99 for 12oz container.Smells like spearment and is a gel.
