It's cough medicine with guaifenesin (sp) as the active ingredient in it but you have to check there are no other active ingredients cos another one may cause the mucus to dry up and not increase it!
I think it was a venos one that I found, I had a cough anyway so had finished the bottle, you take it from start of af to ovulation but no after I think.
Hopefully someone else will be able to give you more thorough info
