Lumbrokinase is a complex enzyme from earthworms. I have discussed this in teaching Cardiology as well as Oncology at the College of Naturopathic Medicine at the University of Bridgeport. Lumbrokinase has been used for thousands of years in Eastern Medicine. In Chinese medicine, earthworms are also called Earth Dragons. It is said to invigorate blood, resolve stasis and unblock.
I use Lumbrokianse as a natural blood thinner like Nattokinase or even Serrapeptase. There are more than 60 studies on Lumbrokinase which need to be read. There is an excellent safety record when you read and observe these studies.
Lumbrokinase has been shown to be safe and effective for treating acute ischemic stroke by lowering blood viscosity. It also has shown to improve efficacy of aspirin.
The enzymes from the Earthworm are beneficial. We need more studies. Keep an open mind.
