SUTRASTHANAM.
211
A concourse of deranged humours, affecting and appearing in a particular part of the body, is called a boil or an ulcer (Vrana) which "is derived from the root "Vri" to cover and is so called from the fact of its covering a particular part of the body or from its leaving a cicatrix which remains the whole life-time of the patient.
Thus ends the twenty-first chapter of the Sutrasthanam in the Sushruta Samhita which treats of investigation into the nature of the humours giving rise to an ulcer.
