Hirudo medicinalis مقابل Hirudo verbana: أيّهما تطلب
Two species dominate clinical practice — Hirudo medicinalis and Hirudo verbana. They are close cousins, but the distinction matters for procurement, documentation and the literature you cite.
For much of the last century, “the medicinal leech” meant Hirudo medicinalis. It remains the reference species in most reconstructive and microsurgical literature. Hirudo verbana, long supplied under the same name, is now recognised as a distinct species and is widely used across hirudotherapy practice.
Hirudo medicinalis vs Hirudo verbana at a glance
| Species | Body size / grading | Typical clinical use | Availability |
|---|---|---|---|
| Hirudo medicinalis | Fine 20–30 mm · Standard 30–45 mm · Large 45–60 mm | Reference species for reconstructive and microsurgery; named in most surgical case reports | Available; supply emphasises published clinical precedent |
| Hirudo verbana | Fine 20–30 mm · Standard 30–45 mm · Large 45–60 mm | Widely used in general hirudotherapy | Broadly available in consistent graded sizes |
Practical differences
- Citation & precedent: Hirudo medicinalis is the species most frequently named in surgical case reports.
- Availability: Hirudo verbana is broadly available in consistent graded sizes for general hirudotherapy.
- Documentation: both are subject to CITES Appendix II export controls; permits must name the correct species.
Which should you order?
For reconstructive and microsurgical indications where you intend to follow published precedent, specify Hirudo medicinalis. For general hirudotherapy where graded, reliably available stock is the priority, Hirudo verbana is often the pragmatic choice. When in doubt, tell your supplier the indication and let them advise.
