    "Sushruta Samhita for the management of Bhagandara (Fistula-in-Ano), Arsha (Haemorrhoids), "
    "and Nadivrana (Sinus). The word 'Kshara' refers to the alkaline, caustic medicament prepared "
    "from the ash of specific plants, and 'Sutra' means thread. A surgical thread is coated with "
    "Kshara (alkaline herbal preparation) and other medicinal substances by a standardised process "
    "of repeated coating, to create a medicated thread that exerts simultaneous chemical and "
    "mechanical action."

    "The proposed Kshara Sutra Changing model provides a comprehensive, hands-on representation "

    "rationale behind this ICMR-validated Ayurvedic procedure. The model will enhance conceptual "
