There’s an entire industry of pedaling them as health products. I once had a random bint on a tour notice my sore back thanks to my scoliosis and asked me about it during some downtime in the tour. After the tour was done she “tipped” me by pouring an amount of essential oil on my palm, told me to rub it on my back, and that if I buy the stuff myself it’ll cure my scoliosis.

I walked to the break room and washed it down the drain. Shit made my hand STANK and my head hurt from the fumes.
