31. The method as in claim 1 wherein said composition further comprises glycerol.
32. The method as in claim 1 wherein said composition is a gel.
33. The method as in claim 1 wherein said composition comprises:
2-30% by weight of a capsaicinoid,
30-70% by weight methyl salicylate,
1-20% by weight menthol,
1-20% by weight camphor,
wherein the percentage by weight of methyl salicylate, menthol, and camphor is greater than 50% of the composition.
