My husband has had a lifelong history of his legs cramping for no apparent reason so I had him incorporate taking vitamin E daily as well as rubbing the muscle pain reliever Banalg on his legs.
Banalg's active ingredients are: menthol at 1.0%, camphor at 2.0%, and methyl salicylate at 4.9%.
Banalg is not for the faint of heart as it has a very distinct odor but does it ever provide temporary relief! As soon as my husband feels a cramp ready to erupt, I rub Banalg on his legs and the pain magically disappears.
Although Banalg is a beautiful shade of green, the bottle states that it is a "fast vanishing lotion" and believe it or not, it is. I put a dime sized amount in my hands, let it emulsify and voila-the lotion is not green anymore therefore, this does not stain.
My husband also has back pains so when he has a long night ahead of him at work, I rub Banalg on his back. He works 10 hour shifts and comes home pain free with no stiffness or soreness.
Since using Banalg, my husband has not had any leg cramps and that gives me peace of mind. I (and my husband!) highly recommend this for temporary relief.
