leech
Hirudinea
Hirudinea is a class of segmented worms, commonly known as leeches. While traditionally used in some cultures for bloodletting and other medical practices, there are no specific traditional uses recorded for Hirudinea itself. Scientific studies have documented the presence of 21 leech species from the Maghreb region, with one study reporting heavy parasitism of a Berber toad by Batracobdella algira. Another study found that macroinvertebrate communities dominated by leeches showed similar composition across two constructed wetlands despite varying water chemistry conditions, and described two new freshwater leech species from Mexico. Fungal communities associated with five species of glossiphoniid leeches included both plant and human pathogens. No major safety issues or drug interactions have been recorded for Hirudinea.

Frequently asked questions
What is leech?
leech (Hirudinea) is a plant documented in FolkKB's traditional-medicine reference, drawn from sourced literature and cross-checked against the evidence.
What does the scientific evidence say about leech?
4 sourced findings are recorded for leech; the strongest carries evidence grade D. For example: The study found that macroinvertebrate community composition, dominated by tolerant taxa including Hirudinea, was similar between two subtropical constructed wetlands.
How strong is the evidence for leech?
The strongest finding for leech carries evidence grade D — preliminary or traditional. Grades run A (strongest) to D (preliminary or traditional).
Is leech safe? What are the side effects?
No major safety issues are recorded for leech in our sources, but the data may be incomplete. Consult a qualified professional before use.
Does leech interact with medications?
No drug interactions are recorded for leech in our sources. This does not rule them out — check with a pharmacist.
What are the common names of leech?
leech is also known as: Пиявки.
Is leech a proven treatment?
No. FolkKB is informational only. Traditional use and early findings are not proof of efficacy or safety — consult a qualified professional and never self-treat.
