Thanks again!Check out this paper. Scroll down to lumbrokinase(page 4) unless you want to know a lot about earth worms. I am researching a podcast on it.
Lumbro, unlike the other systemic enzymes, seems to stabilize the fibrogen system. So it avoids some of the side effects of the other enzymes. Also has possible anti bacteria/anti biofilm effects
The article mentions the TCM supplement called Di Long, which comes from earthworms, and once again, I'm getting a hit at Activeherbs :
Di Long (Earthworm, 地龙)
I'm just not sure whether this is the same enzyme as lumbrokinase though. I'm avoiding buying anything from Amazon, since their automation in order fulfillment tends to make their packaging too large, and I incur additional charges when the package is forwarded to Manila. Amazon has Lumbrokinase though. I should ask Activeherbs to see if the product was made under conditions that don't degrade the product through high heat exposure, which destroys enzymes.
