The Power of Flowers

I was having a conversation with a woman in Central Park this morning, and she swore by Rescue Remedy as a legit chill-out product for dogs. It’s a flower essence that is supposed to relax your pet when he or she is in stressful situations—whether it’s a trip to the vet, to quell separation anxiety, whatever. (Touted as “yoga in a bottle,” it’s also available for humans and has been written about in basically every major magazine.)
Rescue Remedy Pet comes in a dropper bottle, and you’re supposed to put 4 drops in your dog’s mouth, on a treat/food, or directly to his or her nose, ears, or paw.
Has anyone tried this—for yourself or your pet?
