DR elmore, this is what DR Jeanne had to say about anrica. I don't recommend the Arnicare Cream by Boiron. If it made a difference I haven't noticed.
The Arnica Rub is my favorite of the Arnica topicals, since it has lots of other remedies in it as well. About a week ago I started a little trial of Topricin, a homeopathic cream for arthritis. I'm using it on my two arthritic fingers. It's helping. If you don't get results with Arnica, you may want to try Topricin. I've seen in on Amazon. It's very easy to use--no smell, absorbs easily, etc.
Life Extension has a wonderful supplement for arthritis, the Fast-Acting Joint Formula. It contains a high dose of hyaluronic acid and it really is fast-acting. A bit pricey, but very effective.
the Arnica Rub I like is by NatraBio. I see there is also one by A.Vogel, but that one is straight Arnica, the herb. The NatraBio product is a homeopathic combination product.
My cousin swears by Australian Dream for arthritis. I haven't tried it, but it has good reviews. She also uses Arnica for EVERYTHING, except when she's using Australian Dream.
