• Doctrine of signatures: earthworms’ (and other insects’) ability to remove obstructions is indicated by their skill at wriggling through small places or plowing right through the earth.
• Contains the fibrinolytic enzyme lumbrokinase. May have benefit in cardiovascular disease. One study showed “Oral lumbrokinase improves regional myocardial perfusion in patients with stable angina.”
• A very safe herb.
MLT: Insects [and worms] represent the essence of pure neurological instinct reaction that is akin to the manifestation of involuntary reflexes such as spasms, shaking, and stroke.
