Leeches are actually useful in limb reattachment recovery. Sterile leeches are applied distal to the reattachment point to remove excess blood until the veins heal enough to do the job.
My sister and I looked into raising sterile leeches and maggots for wound recovery but the regulatory environment is oppressive, to say the least. Sterile swine and bovines are another lucrative business but the startup costs are very high and the regulations are the same as for leeches and maggots. On the other hand, the leftovers are hand raised, organic pork and beef.
