yep have done, for many years, still do
dont think the modern stuff is as potent as the old
i doubt it is any better than the bengay i have heard about, jits not really a liniment type thing
smells very potent, almost stings the eyes, but i dont think that denotes its strength
i think it would be very expensive to buy huge quantities to use as a liniment type thing
i have mainly used it for small cuts/stings/burns,/colds not so much muscle cramp, if thats what your thinking of using it for
think it was around Centuries ago, prior to all this modern stuff, old ancient Chinese remedy ..
