Today my friend decided to smudge her house while I was over. For those who don't know what this means, she lit sage and "cleansed" her home. The smoke got strong and I excused myself outside. Then I made the mistake of googling the effects on pregnancy and now my paranoid self is nervous! Supposedly can cause problems

has anyone burned sage while pregnant or am I crazy? At first, I equated it with burning incense, which we do on occasion, but now I'm not so sure.
Edit: added sage in title of post
Re: Totally random: burning sage
I am really curious to know what the cleansing properties are sage are? Is it always "spirit" cleansing?
