Osteoarthritis is characterized by inflammation in specific joints – especially joints that are constantly mobile, and may have received age-related damage over time. That inflammation leads to joint pain (in this case, knee pain) with swelling that may contribute to a lack of mobility. Osteoarthritis generally starts mild, but can become worse over time if not treated.
Leech therapy helps relieve symptoms with osteoarthritis of the knee.
Leech saliva contains many bioactive substances, including anticoagulants, analgesic, blood-thinner, vasodilators, antibiotics- like substances , Hyaluronidase, Destabilise, Bdellines, Eglines, Histamine-like substances, Lipolytic enzymes, Lipase, Neurotransmitters, Hormones and many more.
Medicinal leech therapy is used in a variety of conditions; most of which have pain as a major symptom. Its mode of action relies on the injection of leech saliva into patients’ tissues during the process of blood withdrawal. Leech saliva contains active ingredients with anti-inflammatory, thrombolytic, anti-coagulant and blood- and lymph-circulation enhancing properties.
Pain relief from leech therapy is rapid, effective and long-lasting in many conditions.
„Scientists have found the tiny parasitic creatures can bring welcome relief for people who have the condition in their knee. Use of leeches helped to ease both the pain and the inflammation associated with the condition. Leech treatment produced rapid pain relief after three days, with the greatest effects registered 24 hours after treatment. The effects were sustained four weeks later. It seems likely that leeches help to relieve pain because their saliva contains various compounds that have an anaesthetic effect.”
