I run myself down w/ arnica massage oil after a heavy run.
As far as I know arnica etc is just an expensive placebo.
People use the power of prayer Paul and have done for millenia, doesn't mean it doesn't work.Praying there isn't a rct showing statistically significant outcomes etc
OK, not a medic but what about arnica vs placebo?
I know placebo is well documented, just not sure about arnica re is efficacy for pain relief and or reducing swelling & promoting healing.
