We used this stuff called Atomic Balm. It was provided by the trainers. On a cold day before running outside, we would slather the stuff on our calves and hamstrings to help loosen up before stretching. They provided the locker rooms with several gallon jugs and we used huge amounts of the stuff. I don't know if there even was a warning on the label. Unscrupulous team mates would smear the inside of your jock strap or cup with the stuff if you were stupid enough to leave the gear out. Not fun when you discovered you were "Bombed" a mile into a twenty mile run.
Really sad the young lady had such a reaction.
Much sympathy to her family and friends.
