Arnica Montana is it good to use before surgery?

Omega 3 fats (e.g. fish oil, EFA, flax seed oil, Krill oil), NSAID's (aspirin, ibuprofen, naprosyn), Vitamin E, "blood thinners" and a whole host of supplements and medicines can cause excessive bleeding and bruising and therefore increase your recovery time. When in doubt stay away from supplements unless they are designed for surgery. I offer to my patients specific supplements that speed healing, reduce swelling, bruising and in some cases minimize discomfort (for example Bromelain, Arnica Montanum, and Vitamins designed for surgery.Bottom Line: Certain vitamins and minerals can speed healing others can cause problems and slow the process down or cause complications. If healing is going well I usually let my patients go back to their usual regimen of supplementsCheck with your doctor as only your doctor would have access to your medical history and what would be best for you. We typically allow our patients to continue their supplements 10 days post op if their recovery is going well.

Arnica is one of the few herbal medications that gets frequent endorsements by Plastic surgeons,  I recommend it for all my facial procedures including injections.

This is something you should discuss with your surgeon. For my patients, I have them take VitaMedica Surgery Program both before and after surgery which includes arnica montana and we have had good results. Good luck!
