First to answer your question from your other thread...
Rescue Remedy is an herbal product that is made for humans, but is often recommended for dogs, too. It has a calming effect. Look for it in health food stores.
DAP = dog appeasing pheromone. The diffuser is like an air freshener that diffuses a scent that is calming to dogs. It is often recommended for separation anxiety. It's also often recommended for dogs with noise phobias - like to fireworks or thunder. Here is the UK, it is available from vets. In the US, it may be more widely available, I'm not sure. Do an online search for it. Oh, by the way, the scent is not at all offensive to humans (you can barely smell it all).
As for the crate, I most definitely would NOT just put her in there for long periods of time. It would keep her from being destructive, but I have serious doubts about whether it would actually calm her or not. Personally, I think just putting her in there and locking the door would make her anxiety worse.
If you go with the crate, I recommend that you take steps to make the crate a pleasant experience for her. Here are a couple of articles on that topic:
