which goes on growing worse with the progress of the day and begins to abate only when that great luminary begins to set in the western sky, is called Suryávarta. It (generally) abates on the use of cold articles but sometimes on that of warm things as well. It is ascribed to the concerted action of the three Doshas. 10.
Symptoms of Ananta-váta Śiro-roga: — The disease of the head in which a violent pain is felt at the Manyá and the Ghátá (the two nerves on the backside of the neck) which ultimately affects the region of the eye, the eyebrow and the temples and specially produces a throbbing of the cheek, as well as paralysis of the jaw-bone and the eye. The disease is known as Ananta-Váta and is due to the concerted action of the three Doshas. 11.
Symptoms of Ardhávabhedaka and Śamkhaka: — The disease of the head in which a violent and excruciating pain of a piercing or aching nature is felt in one half of the cranium which makes the patient feel giddy, and which either follows no distinct periodicity or recurs at a regular interval of ten days or of a fortnight, is called the Ardhávabhedaka and is due to the concerted action of the three Doshas. A violent pain caused in the head and more especially in the temples by the local Váyu in combination with the deranged Kapha, Pitta and blood is designated by the holy sages of Áyurveda as the Samkhaka. It produces a very great pain, and is very hard to cure even by the joint advice of thousands of physicians and is as fierce as death itself. 12-13.
Thus ends the twenty-fifth chapter in the Uttara Tantra of the Sus'ruta Samhitá which deals with the symptoms of the diseases of the head.
