Hello, i am no practioner of kung fu of any kind but my friends practice wing chun and were exposed to a bone hardening "potion" if you want to call it that, I was told it was for iron palm conditioning and did a little research and found something with the same discription called dit da jow.(Iron palm liniment)

I was wondering if it would still be beneficial to use it not for the purpose of practicing Iron Palm which it is used for but for the sole purpose of bone hardening to condition for a different form of MA?
