“…The wetlands selected for the present study are the main areas, where the commercial leech collection is conducted, around Lake Eğirdir. The studied wetlands are distinctly isolated from the lake, being far from each other, rich in macrophytes, being shallow, and rich in food in the form of hosts for leeches (Ceylan, 2016;Ceylan and Çetinkaya, 2017;Ceylan et al, 2021a).…”

“…Although Turkey is an important supplier of medicinal leeches, leech gathering has been done without information of their biological characteristics, reproductive behavior, and population structure (Kasparek, 1998). The intensive use of leeches in medicine, habitat destruction and over-collecting have led to a gradual decrease of medicinal leech populations in European wetlands and they have completely disappeared in some wetlands (Elliott and Tullett, 1984;Elliott and Kutschera, 2011;Sağlam, 2011;Elliott and Dobson, 2015;Ceylan and Çetinkaya, 2017). International medicinal leech trade, therefore, is conducted under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) (Collier et al, 2016;CITES, 2021;Uğural and Serezli, 2020).…”

In the present study size and structure of the Mediterranean medicinal leech (Hirudo verbana Carena, 1820) populations inhabiting wetlands around Lake Eğirdir (Turkey) were investigated. Population size was estimated by removal methods, age classes were estimated for the first time in leeches (Hirudinea) using “Modal Progression Analysis” of body length frequencies using Bhattacharya's method. The population size and biomass of medicinal leeches around Lake Eğirdir were estimated to be 1,562,696 ± 805,613 leeches and 467.26 ± 172.91 kg, respectively. Three age classes were identified; the age group of 0+ was dominant with 78.6%. While 89.9% of the individuals weighed less than 1 g, whereas the broodstock was estimated to represent only 7%. Body weight, body length and condition factor were found to be 0.52 ± 1.19 g, 4.5 ± 2.4 cm and 0.620 ± 0.123, respectively. This study reveals that the population size of H. verbana in the wetlands around Lake Eğirdir is relatively well preserved and there is no significant threat to the sustainability of the exploitation of the medicinal leech populations. It is concluded that the stability of the lake's water budget, the variety and abundance of the host in the undamaged wetlands, the socioeconomic structure of the leech collectors, the sales policies, and the effective activities of conservation and control units might affect conservation status of the medicinal leech populations inhabiting wetlands around Lake Eğirdir.

“…However, very few of them function as "medicinal leeches" (11). Leech species that are frequently used in medicine and subject to international trade are in the genus Hirudo (12,13). A total of seven species (Hirudo medicinalis, Hirudoverbana, Hirudo orientalis, Hi rudo troctina, Hirudo nipponia, Hirudo sulukii and Hirudo tianjinensis) have been described in the genus Hirudo.…”

“…(24,35). The leech export quota of Türkiye, which was 10,000 kg/year in 1996, has however gradually decreased due to the diminishing of medicinal leech populations in nature and was approximately 1,500 kg in 2022 (13,36). The increasing demand for leeches cannot be met adequately by either aquaculture facilities or nature.…”

Since ancient times humans have used a variety of plants and animals to both prevent and treat ailments. Hirudotherapy is a traditional treatment modality using medicinal leeches. In both traditional and modern medicine, medicinal leeches have been important in the treatment of eczema, chronic ulcers, psoriasis, osteoarthritis, thrombosis, and hypertension. Hirudotherapy is a trustworthy, easy-to-use, helpful, and affordable treatment option for draining blood from deeper tissues in localized venous congestion related with surgical replantations and flap reconstructions. Hirudotherapy has also been commonly used to treat soft tissue oedema and haematomas in trauma situations. Throughout the feeding process, leeches secrete biologically and pharmacologically active components into the wound. This article aims to present a broad assessment of the potential use of hirudotherapy, indications, contraindications, and therapy-related complications. Providing detailed evidence-based information about the usage areas of hirudotherapy will help spread healthy medicinal leech practices and prevent possible complications, thus infectious diseases and public health problems.
