sandybeach,
ByGosh, and anyone else interested in reading this... As a Registered Natural Medicine Practitioner I use Arnica quite frequently in my practice.
Arnica (Arnica montana) has been used for medicinal purposes since the 1500s and is still popular today. Applied to the skin as a cream, ointment, liniment, salve, or tincture, arnica has been used to soothe muscle aches, reduce inflammation, and heal wounds. It is commonly used for injuries such as sprains and bruises. As an herb, arnica is generally used only topically (on the skin) because it can cause serious side effects when taken by mouth. Oral homeopathic remedies do contain arnica, but they use an extremely diluted form that is not considered dangerous. If you have any question about whether you have the herbal or homeopathic form of arnica, talk to your doctor before taking it.
I made up a mixture of three different tinctures to use topically in hospital to elevate the swelling, bruising and to assist the healing. Because it is classed as an Astringent, it acts to break up the bruises and disperse the tiny clots that may form and congregate. It has the ability to move them into the normal elimination patterns of the body. The medical staff including my OS were most interested because I was able to reduce the swelling down quickly and did not get any bruising!
