Theres an antivax facebook group, and someone made an fb smurf account i think, and told everyone there about this new treatment for unhealthiness, and they said "i was feeling under the weather, and my homeopath(is that the right thing? I cant remember) told me to put mustard on my body, and have a shower, and i walked out feeling 100% better!"
They responded
"Thanks for the info!"
They actually smeared mustard on themselves just because someone said so and it wasnt prescribed by an expert in medicine.
