I bought a bulk bag of nettles and RRL (and red clover) I was doing an infusion with all 3, but now I'm cutting out the red clover and cutting back on the RRL for the first trimester. I usually do a small handful of each herb, put it in my french press and pour boiling water over it and then let it steep for at least 4-8 hours or overnight, depending on when I find time to make it. Then I drink it hot or cold. Instead of a small handful of RRL I'm going to cut it down to about a tablespoon for the 1st trimester.
I also like to make infusions of oatstraw...and I'm going to get all the ingredients that are in the earth mama angel baby nausea tea and make a batch of that as well.
