The patient have a disorder to be treated with leech should be asked to sit or lie down.Then the shodhita leech should be applied to the diseased spot.Their mouth should be covered with smooth white and moistened cotton swab. When the leech starts opening its mouth like horses hoof and raising the shoulders it is the sign that the leech is sucking the blood.If the leech does not start sucking blood then ksheera or a drop of blood should be kept over the affected part and the leech will start sucking the blood. If at the bitting site needling pain and itching appear it indicates that the leech is sucking pure blood, by pouring rock salt at its mouth.
As soon as the leech is removed it should be dipped in dilute saline water, turmeric water and plain water one after the other. By this process the leech vomits out the blood immediately. Once used the leech is not fit to be used again for atleast seven days.
TREATMENT OF THE PATIENT
After the leech has detached blood from the sucked area should be allowed to flow for 1-3 minutes and then dressing should be done with jathyadi ghritham.
Starting of pruritis and subsiding of redness and pain are indications of removal of vitiated blood.
Praechana is a type of raktamokshana. Superficial incisions are made over the skin with the help of a scalpel, fine needles or instruments. It is applied over the elevated portion of the skin locally where few superficial incisions should be made. The part proximal to the incision should not be made in marmasthalas, snayus, sandhis and asthis.
Blood letting with this method is commonly used in localised blood disorders and in certain skin disorders. Praechana must be done after taking aseptic measures. Antiseptic dressing should be applied over the mankind.
