“Medical-grade” is not a marketing word. For leeches it is a chain of controlled conditions that together make the animal safe and predictable to use on a patient.
Bred, not foraged
Wild leeches carry an unknown history — diet, pathogens, age, water quality. Controlled breeding replaces that uncertainty with documented provenance, consistent health and reliable grading.
Fasted and conditioned
A hungry leech attaches and draws; a recently fed one does not. Fasting and conditioning are what make a leech behave on demand in the operating room.
Graded and documented
- Size-graded so the animal matches the procedure
- Batch-traceable from breeding line to dispatch
- Accompanied by health and CITES documentation
