Panchakarma is a specialized branch of Ayurveda that primarily deals with the body's purification (Shodhana) of doshas. As we know, the word Panchakarma refers to five special therapeutic procedures like Vamana, Virechana, Vasti, Nasya and Raktamokshana. Raktamokshana is an effective bloodletting therapy. Classically it is described as of six types, i.e. (1) Shringa, (2) Jalauka, (3) Alabu, (4) Shiravedha, (5) Prachchhana and (6) Ghatiyantra. In the present study, a clinical trial has been done, especially in the disease of Gridhrasi, with particular reference to Sciatica by combining Parchchhana and Ghatiyantra, a modified form of Raktamokshana therapy, called Multiple Vacuum Syringe Blood Aspiration Procedure (MVSBAP). Sciatica is painful neuralgia of the Sciatic Nerve in which pain starts from the gluteal region and buttock and comes down through the back of thigh, knee, calf and outer border of the foot. Sixty patients were selected for the clinical trial using a simple random sampling method from the OPD and IPD of Government Ayurveda College and Hospital, Varanasi, Uttar Pradesh, India. Two groups are made like Group-A and Group-B, each consisting of 30 patients. Patients of Group-A are treated with only traditional Ayurvedic medicines, and patients of Group-B are treated with MVSBAP and traditional Ayurvedic medication. After one month of final treatment, assessment is done on statistical parameters, which show pretty better results in Group-B patients. The application of MVSBAP in the disease of Gridhrasi draws a new horizon to the ailing humanities.
