These are protease enzymes, which reduce inflammation. And since they digest proteins they can also work on blood clots and scar tissue if taken in the absence of food.
There are herbs that do the same thing. My favorite is dan shen (red sage root), and there is ginger. I prefer the herbs because they are less expensive, and offer more benefits.
Keep in mind though that all of these thin the blood so they they need to used cautiously if using other blood thinners. And avoided altogether if on Coumadin.
