What is Leech Therapy
The benefit comes from what the leeches inject into the tissues through their salivary gland secretion (SGS) in exchange for some blood.
Hirudotherapy is a holistic, all natural full body healthcare system that uses specific types of medicinal leeches to treat a wide variety of problems and diseases, systemic chronic and acute.
Hirudotherapy is more than just a better alternative to venesection or bloodletting, it utilizes the uniquely complex, and still not fully defined secretion from the medicinal leeches’ salivary glands to work what some call medical miracles.
​
Hirudotherapy is also encouraged and used for detoxification, health maintenance and illness prevention, which are main components of any holistic system who’s focus is maintaining health, not treating illness.
​
Most people refer to what the leech secrets as hirudin but actually that is only the main anticoagulant. The saliva from the leeches’ salivary glands actually contain over 120 (150-300 new research) different bioactive substances, some of which have been classified, while others are only defined by medical research as hirudo-enzymes, bioactive substances and proteins. Here is a list of some of the better known substances.
A Brief History
Within the last 200 years, leeches were used worldwide for medicine.
New tools excavated from archeological sites have dated venesection (blood letting) to the Stone Age.
Some of the earliest clearly document records of leeches being used for medicinal purposes come from Africa, Mesopotamia and India in the form of paintings on tombs and ancient Sanskrit writings. Traditional Chinese Medicine also documents the use of leeches in their medical literature.
Other cultures that are also known to have used leeches for healing are the Maya, the Aztecs, Greeks, Romans, Persians.
In the 8th century B.C. in a poem, Homer writes “A leech is worth many other men for the cutting out of arrows and the spreading of soothing medicaments”.
Indian physician Sushurta is credited with the most extensive literature on leeching in India.
Why Leech Therapy?
From Matt Isaac's book: Leech Therapy An Introduction to a Natural Healing Alternative
“Leech therapy can be used as an anti-atherosclerotic treatment (athersclerosis is when artery walls become thicker and harder due to buildup of cholesterol); against muscle spasms and high blood pressure (hypertension); against thrombosis; and to fight many more diseases. The list of leech therapy applications is so long, that it would lead you to believe that modern medicine would employ leeches as full time doctors. But, unfortunately, that is not the case. Instead, billions of dollars are poured into designing “quick fixes” for the masses.
​
There have been many substances from leech SGS (salivary gland secretion) that have been isolated and their effects identified. There remains many substances that can be seen though electrophoresis, but remain unknown in name and function. There remains an element of mystery still to be discovered.
​
-
Hirudin: Anti-coagulant, more powerful then pharmaceutical blood-thinners
-
Orgalese: Brings micro-circulation back, creates and restores micro capillaries
-
Calin: Inhibits blood coagulation, inhibits collagen and mediated platelet aggregation
-
Destabilase: Dissolves fibrin, thrombolitic effects
-
Bdellins: Anti-inflammatory
-
Eglins: Anti-inflammatory
-
Hyaluronidase: Antibiotic, increases viscosity
-
Chloromycetyn: Antibiotic effect
-
Tryptase Inhibitor: Inhibits proteolitic enzymes of host mast cells
-
Factor Xa Inhibitor: Inhibits the coagulation of factor XA by forming equimolar complexes
-
Compliment Inhibitors: Replaces natural compliment inhibitors if they are deficient
-
Carboxypeptidase A Inhibitors: Increases the inflow of blood
-
Histamine like substances: Vasodilator, increases the inflow of blood at the bite site
-
Acetycholine: Vasodilator
-
Anesthetic

How it Works With Heart health
With all our knowledge on healthy lifestyle and heart health the number one killer still remains cardiovascular disease and thrombosis remains a significant factor in causing the heart disease. It is also well documented that thrombin is the primary enzyme responsible for coronary thrombosis or the clogging of the arteries.
Let's take a closer look at some specifics of heart health and compare the use of natural Hirudin with it’s closest competition for venous congestion and complications which is heparin.
Factors related to the clotting process:
Factor Xa converts the prothrombin zymogen to its active form thrombin. Thrombin converts fibrinogen to fibrin and triggers the conversion of fibrin to cross-linked fibrin, and activates coagulation cofactors V and VIII. Once fibrin forms, thrombin attaches to it and amplifies its own generation 300 – 500 fold. Since this is the process that leads to the need for blood thinners for many problems, it has been the position of the medical world to focus on the direct inhibition of thrombin which is the main component in the process.
-
Leech salivary gland secretion is the best naturally occurring thrombin and Factor Xa inhibitor known.
-
Hirudin is a 3 to 5 times stronger anticoagulant than heparin.
-
Hirudin does not require any cofactors to be effective while heparin requires plasma cofactor antithrombin III in order to work, resulting in the progressive depletion of natural anticoagulants.
-
Hirudin does not consume antithrombin III (better for those with antithrombin III deficiency) no need for antithrombin III replacement therapy.
-
Hirudin is not inactivated by antiheparin proteins, whereas the use of heparin can lead to heparin resistance in patients with inflammatory or malignant disorders.
-
Hirudin has no direct effects on platelet or endothelial cells, whereas heparin may contribute to associated risk of bleeding. Heparin use runs the risk of developing the side effect heparin induced thrombocytopenia.
-
Heparin can not inactivate fibrin-bound thrombin (thrombin already attached to fibrin).
-
Hirudin also binds non specifically to other agents in the blood, not only thrombin.
-
Hirudin is a direct active-site inhibitor with the ability to bind to clot-bound thrombin, it does not require access to the heparin receptor.
-
Heparin is an indirect inhibitor and relies only on attaching to one of four receptors on thrombin, the heparin receptor. When thrombin binds to fibrin, the heparin site is inaccessible and heparin is useless.
-
Platelet Aggregation which is the clumping together of platelets in the blood, is part of the sequence of events leading to the formation of a thrombus (clot), and is also more effectively treated using hirudotherapy (SGS) over heparin or other modern medicines.
The Complicated Process of the Clotting Cascade (below)​
Pain Management
SGS (salivary gland secretions) input substances such as Carboxypeptidase A Inhibitors which increases blood flow and orgalese which stimulates the growth and restores microcirculation while bdellins and eglins are powerful anti-inflammatories injected deeply into the tissues.
Blood Circulation
Heart disease is the top killer in North
America, higher than cancer deaths. The main application for hirudotherpy is for the cardiovascular system. Many of the SGS contain beneficial substances that directly benefit the heart such as hirudin, orgalese, calin, destabilase, factor Xa inhibitor, carboxypeptidase A inhibitors, and acetycholine.
Skin Rejuvenation
For skin to look it's best, it needs oxygen rich blood flowing to all of the cells. Orgalese stimulates the growth of microcirculation to tissues and carboxypeptidase A inhibitors increase blood flow to the area.
Holistic Wellness
Hirudotherapy views the body as a whole unit, that is what holistic therapy does. In order to treat disease or to maintain health, leeches are commonly placed over the organ systems each session. This is known as the hirudo-complexo therapy. People commonly report that they feel lighter, sleep better and have more energy.
Inflammation Reduction
Leech therapy is known to treat any condition where inflammation is a factor. This is one of the reasons that hirudotherapy is so effective for many different ailments. All of the SGS work together, but there are specific substances that have an anti-inflammation effect such as bdellins and eglins.
Stress Relief
When your body is working in harmony, you will feel great. Did you know that your thoughts have roots in your digestive system? The balance of good and bad bacteria in the gut can influence the types of thoughts that you have. SGS from leeches can also affect the health of the digestive system. Many people report a feeling of wellbeing on the day they receive leech therapy.
