I just put some on my sore back
, and I have the container in front of me.
Active ingredient: Methyl Salicylate 29%, Menthol 7.6%. The rest is a balm of Paraffin and White Petrolatum.
I bought it after some comparison shopping tonight, and noted that this is much higher than Ben Gay, which has about 15% Methyl Salicylate as its active ingredients.
Long ago, when I was young and stupid, I thought it might be a good idea to try and masturbate with this stuff as a stimulant. The feeling was indeed intense, but after the orgasm, I discovered to my horror that it would not go away, and it started to feel as though I was on fire down there. I sprinted to the shower, but the slimy hydrophobic mixture did not wash off easily, and I spent the rest of the day wearing some especially loose pants and cringeing when I had to urinate.
