I had an injured knee that was as bad as it could be without having to operate. I went for over a month without much improvement. Ended up healing it by using large doses of oligomeric proanthocyanidin (OPC). And at the same time I used large doses of An enzyme product called Somazyme.
The OPC's are a super powerful antioxident. The enzymes are taken on an empty stomach so they won't digest food but instead are used by the body to tear down and replace bad tissues.
