Kshara Sutra is a time-tested, minimally invasive, minor surgical technique in Ayurveda, primarily used for managing anorectal diseases like anal fistula and haemorrhoids (piles). The term ‘Kshara’ refers to a caustic, alkaline substance derived from the ashes of medicinal plants, and ‘Sutra’ means a thread. This unique mechanism has made it a preferred treatment for conditions traditionally requiring complex surgery.
The procedure involves a specially prepared medicated seton thread coated with successive layers of Ayurvedic herbs and their alkaline ashes (Kshara). This thread (Kshara Sutra) is strategically placed through the pathological tract (like a fistula channel or the base of a pile mass). The thread continuously releases medicine into the tract, performing a ‘cutting’ and ‘healing’ action simultaneously. It works by reducing inflammation, pain, and swelling while helping the body eliminate waste materials and toxins.
The Kshara Sutra procedure is performed under sterile conditions by a trained Ayurvedic surgeon and is often an Outpatient Department (OPD) procedure, requiring only brief hospitalisation or none at all.
Patient Assessment: A thorough examination, often involving a fistulogram (for fistulas) or proctoscopy, is done to ascertain the exact path, depth, and extent of the tract. Next, the procedure is typically performed under local or spinal anaesthesia to ensure the patient’s comfort.
Preparation of the Kshara Sutra: The thread is prepared over several days by repeatedly coating a surgical linen thread with latex from the Euphorbia neriifolia (Snuhi), followed by fine powders of alkaline ash (Kshara) (e.g., from Achyranthes aspera (Apamarga)), and sometimes turmeric and other antiseptic herbs.
Probing and Insertion: A special malleable probe is guided through the external opening of the fistula and out of the internal opening (or through the base of the pile mass). The Kshara Sutra is attached to the probe and carefully drawn along the entire length of the tract. The two ends of the thread are secured and tied together at the external opening. For fistulas, this ensures the thread forms a complete loop within the tract.
Follow-up and Replacement: The Kshara Sutra is allowed to remain in place. Due to the continuous action of the medicated thread, it gradually cuts and clears the diseased tissue (cutting-cum-healing). The thread typically cuts a small portion of the tissue (about 1-2 cm) per week. The physician replaces the thread with a freshly medicated one every 5 to 7 days until the entire tract is cut through and healed from within. The duration depends on the length of the fistula tract.
Post-treatment Care: Patients are advised on proper hygiene, regular Sitz baths (warm water bathing of the anal area), and specific dietary recommendations (high fibre, avoiding spicy/fried foods) to ensure soft bowel movements and promote healing. Oral Ayurvedic medicines may be prescribed to control pain and inflammation.
The Kshara Sutram therapy typically requires 2-4 sessions, depending on the severity of the condition. Each session may last between 15 to 30 minutes. The entire healing process can take from 3 weeks to several months, depending on the condition being treated.
Kshara Sutra therapy is the gold standard Ayurvedic treatment for specific anorectal conditions and is gaining international recognition for its efficacy.
