It neutralizes the accumulated pitta toxins of blood. leeches are applied on the affected area of patient. Leeches have tiny rows of teeth. They pierce a person’s skin and insert anticoagulants through their saliva. The leeches are then allowed to extract blood, for 20 to 45 minutes at a time.
Enzymes in saliva of leeach (Hirudin) enter the blood which acts as an anti-coagulant. This leech enzyme stays in the blood and do vasodilation and increases the blood supply to the surrounding tissue. This prevent necrosis and expedites the healing.
Leech sucks impure blood from the skin and only the pure blood is left so it is a blood purification therapy .
Toxins present in the gastrointestinal tract are absorbed into the blood and circulated throughout the body. This condition is called toxemia, which is the basic cause of repeated infections and blood circulatory conditions. This includes repeated attacks of skin disorders such as urticaria, rashes, herpes, eczema, acne, scabies, leukoderma, chronic itching or hives. In such conditions, elimination of the toxins from blood is necessary.. Rakta moksha is also indicated for cases of enlarged liver, spleen and gout.
Pitta is produced from the disintegrated red blood cells in the liver. So pitta and blood have a very close relationship. An increase in pitta may go into the blood causing toxicity, and thus many pitta-genic disorders. Extracting a small amount of blood from a vein relieves the tension created by the pitta-genic toxins in the blood. Leeches have been used as an alternative to bloodletting. Bloodletting also stimulates the spleen to produce anti-toxic substances that help to stimulate the immune system. Toxins are neutralized, enabling radical cures in many blood-borne disorders.
Certain substances such as sugar, salt, yogurt, sour-tasting foods and alcohol are toxic to the blood. In certain blood disorders these substances should be avoided to keep the blood pure. For rakta moksha treatment other than bloodletting, there are blood-purifying practices involving herbs, gem
“You watch it swell up on your blood, watching it get fatter and fatter - then when it’s super drunk on your blood it just kind of rolls over like it is stumbling out of the bar.”
The actress, who was formerly married to Bruce Willis, is convinced the treatment worked.
“I’m going back – I only got four leeches and I felt a bit cheated,” she added.
Leeches have been used in medicine for centuries and were first employed in Egypt about 2,500 years ago.
They are often used today in plastic and reconstructive surgery, because the anticoagulant they secrete fights blood clots and restores blood flow to inflamed body parts.
In 2008, the union health ministry decided to recognize leech therapy to treat a range of diseases, including eczema, gangrene, vascular reconstruction and vascular surgery in chronic wounds.
The technique is in vogue in Jammu and Kashmir, coastal Orissa, Andhra Pradesh and some parts of Gujarat. Now the therapy is also practiced in some clinics across metropolitan cities such as Delhi and Mumbai.
Divya Sharma, 47, a resident of east Delhi’s Rohini area, says she found the treatment very effective and life-saving. “I had suffered serious injury to my legs in an accident some months back. The wounds turned gangrenous and doctors said they might have to amputate my legs if the injury does not heal. Then a friend advised me to try leech therapy. After I started it, my injuries began to get better day by day. The doctors said no operation was required.”
The first description of leech therapy, classified as blood letting, was found in the text of Sushruta Samhita (dating 800 BC) written by Sushruta, who was also considered the father of plastic surgery, according to information on the web.
The application of medicinal leeches for cleaning the blood of poison was used in Egypt around 2,500 years ago. The therapy was common until the mid-1800s when newer therapies took their place.
In the 1980s, medicinal leech therapy got a big boost by plastic surgeons who used leeches to relieve venous congestion, especially in transplant surgery. In 2004, use of blood-sucking leeches was also approved by the US government as a tool for healing skin grafts and for restoring circulation.
