Chapter CLXXXVII - The Nidanam of aphonia

Dhanvantari said:—Now hear me, O Sushruta, discourse on the Nidanam of Svara-Bhanga (aphonia). The deranged Vayu etc, aggravated by loud talking, loud chanting of the Vedas and loud recitations of verses, etc., affect the vocal chords, and give rise to Svarabhanga (aphonia) Which may divided into six different types. In the Vataja lorm (form?) of aphonia the stool, urine, face and the eyes of the patient assume a black colour and the voice somewhat resembles the harsh brayings of an ass. The stool, urine, face and the eyes of a patient, suffering from an attack of Pittaja aphonia assume a yellow colour, and a burning sensation is experienced in the larynx at the time of speaking. In the Kaphaja type the voice becomes small and weak owing to the obstruction of the larynx with mucous, which, when it melts under the influence of the solar heat during the day, allows the patient to speak in a stronger and clearer voice.
