Anyone do holistic healthcare or anything with Tinctures

I have strep throat pretty bad and I've always used sage tincture since I'm allergic to the medicine the doctors give but now that I'm in my tww I'm nervous that its not good to take when you're pregnant/trying. Can you still take it? Also I'm sorry about which group this is in I tried the holistic and got no answers :/ *edit* ok not once did I ever state that I wouldn't take a child to get medicine for the love of God this is something I prefer for myself personally. The alternative medicine they give doesn't work. This is what I've found works for me. Simply asking if I do end up being pregnant could it have negative effects and in asking those that take them. Not those that don't.
