factual data is hard to come by regarding CS because there are no real scientists getting paid to do the research. this leaves CS TOTALLY in the realm of self experimentation and volunteer research. when i engage in these activities, i like to err on the side of safety as much as possible. plus, i am not much into coddling my body so a little discomfort does not bother me a bit.
what you say about mixing CS with salt makes sense. can you reference this info somewhere else? have you done this yourself?
