It is one of the most important Shaivite shrines are popularly known as Vaitheeswaran Koil. Vaidhyanathaswamy or Vaitheeswaran (God of medicine) got his name as he has cured Angarakan of his leprosy here.
Legend has it that Angaraka was suffering from leprosy and was cured by Lord Vaidhyanathaswamy. Hence, it is believed that a bath in the holy waters of the Siddhamirtham tank will cure all diseases. It is also said that Lord Ram and his brother Lakshman did the rituals for Jatayu here. As such a pond is found here called Jatayu Kundam. Another importance of the temple is that the Saptarshi or Saptarishi have worshipped Lord Shiva here.
It is believed that a bath in the holy waters of the Siddhamirtham tank will cure all diseases. Devotees come here to get relief from various diseases and health problems.
The term Navagraha denotes the nine celestial bodies which are central to astrological calculations (and beliefs) (and not the nine planets as it is frequently erroneously translated). Certain planetary conflagrations give rise to strong negative effects called “Doshas”. The Navagraha Temples Puja eliminates the ill effect of these planetary movements. The duration of this puja is 1 year on every Tuesday.
