To use Sitaram Karutha Vattu effectively, first, gently warm the tablet on a low flame. Once heated, grind it into a smooth paste. Apply the paste directly to the affected area and cover with a clean cotton bandage to retain the application. For optimal results, ensure the area is clean and dry before application. Follow the recommended frequency and duration of use as advised on the packaging or by your healthcare professional. Always conduct a patch test if you have sensitive skin.
