What are the uses of liniments?

For muscle pains, bruises and sprains; apply this liniment to the affected area and massage in gently.

A waiter brought us a very potent cocktail of something, that smelled of horse liniment and Brain naturally drank both glasses.

I wouldn't use it. The amounts and strength of the herbs in the liniment is completely unknown. Natural does not mean safe.

We got it on a recent trip to Oklahoma. My husband has been using it... he is a 50-something year old soccer referee and does up to 10 games a week and has been known to do a few tournaments per year...

Using " Has " is referred a past tense. Such as: He has taken the garbage out already. Using " Is " for example is referred a Present tense. Such as: He is taking out the garbage.
