CS>Nebulizing CS

[Melly Bag]

I've been making my husband nebulize 2 oz CS with 1/4 tsp MSM every single day 
for the last three weeks due to the epedimics going around.  Many in his office 
are sick and coughing.  I would like your advice if it is safe to nebulize with 
MSM long term.  If it is not harmful i would like him to continue until flu, 
norovirus, etc. are over.
 
Thanks to you all.
