This morning I woke up with a shocking cold (hope its not swine flu). It is mainly a head cold at the moment but my nose is so blocked I can't breath at all. My eyes are continously watering and my head is pounding. I am 30 weeks pregnant. I was wondering if anyone knows if it is ok to use TAAV Mentholaire vapouriser fluid in a vapouriser when pregnant? The ingredients are

Eucalyptus Oil 100mg
Menthol 97.6mg
Methyl Salicylate 13mg
Camphor 5.9mg
Propylene Glycol 600mg
Ethanol (alcohol) 225mg

I have googled it but can't find any info.
