I use a product which contains the same flower essences as rescue remedy, but is made with Dr. Bach's original formula - using Brandy as a base.The product is Feel5ive, produced by Feel Bach! (http://www.feelbach.com)
Not only is it the original recipe, the price is much more reasonable.
I swear by this not only for myself, but for rescued cats and dogs who are fearful and upset. It calms them and helps them adjust to life in a kennel cage, and/or life without the humans they knew. It also helps dogs who have been abused and are thus fearful of humans. I recommend it to anyone who adopts a dog or cat to help them settle down and transition into their new home environment.
For myself - it helps me get through stressful situations. For instance, going to the dentist, which I have feared since childhood.
