Last year while pregnant, I’d text my midwife constantly with “is this plant safe?!” questions & pictures. One thing she encouraged me to consume was nettles (any and all) and DANDELION! She said “any chance you get, eat dandelion.” There are no contraindications, it’s loaded with good nutrients for mom&baby, and it can be added to smoothies or salads or stirfry or tea… so many possibilities. I also like dandelion “coffee” when pregnant since I try to limit my caffeine intake to one cup a day; caffeine free herbs fit the bill.
Summer purslane is another great pregnancy forage for all that omega-3, but I tried not to go too wild on any tart herb assuming it has a higher oxalic acid content. Wasn’t worried about smaller amounts tho.
