Arnica for Swelling and Bruising?

There's no scientific evidence to support the use of arnica preop or postoperatively for the purpose of decreasing bruising and swelling.

Arnica and bromelain are used in my practice to decrease bruising and speed up the swelling portion of healing process after surgery. While these are not prescription drugs, there have been studies to show their efficacy and they certainly cannot hurt to consume before-and-after surgery.
