We swore by this when our son was teething. It feels wild that it works so well, because its topical vs inside the mouth and it feels like some sort of gypsy magic....but DANG, it really does work!
BUT the biggest surprise I found with this, is it works for each aches too! I have inner ear issues and I once had an earache and thought "oh this might work..." and wow the relief was mindblowing!! My son had ENT issues and before his grommets, he'd have chronic ear infections - so I used it on my sons outer ear/cheek/jaw and noticed it relieved his ear pain too!
The smell is so good, and even when I smell it now it brings back big nostalgia of snuggling my baby (and not in a bad way, because it really did calm his teething pain so quickly!)
