Some essential oils that are often listed for use while breastfeeding include basil, clary sage, fennel, lavender, myrrh, orange, peppermint, chamomile, and ylang ylang. Because breastfeeding can be a sensitive time for both mother and baby, essential oils should be used carefully and in moderation. Many people prefer gentler methods such as diffusing or well-diluted topical use, while avoiding direct application near the breast area unless guided by a qualified healthcare professional.
