Post knee surgery I had bruising for 5 days until I remembered my arnica and St. John’s wort which I started using on day 6. Surgeon told me it would be another 3 weeks before the bruising went due to the intensity of the surgery but by day 7 all bruising was completely gone after 2 days of using it. This stuff is amazing, genuinely. Start by buying a small tub, i guarantee you will buy a large one next time. The large jar lasts four family of 3 about 12 months, you only need a small amount
I have been using this for a long time and I find it really helps
