Vaitheeswaran or the “God of healing” and it is believed that prayers to Vaitheeswaran can cure diseases. It is one of the nine Navagraha (nine planets) temples associated with the planet Mars (Angaraka). The village is also known for palm leaf astrology called Naadi astrology in Tamil.
The holy waters of the Siddhamirtham tank within the temple complex contains nectar, and a holy dip is believed to cure all diseases.
During the Ramayana period, Rama, Lakshmana and Saptarishi have worshipped the deity in this place. There is a pond at this temple called Jatayu kundam (pot of Jatayu having holy ash of Vibhuti). One of the nine planets, Angaraka (Mars), suffered from leprosy and was cured by Vaidhyanathaswamy and from then on it is treated as one of the Navagraha Temples for planet Angaraka. Parvati, the consort of Shiva, asked her son, Subramanya to appear with one face from his regular appearance of six faces. When he did so, she was pleased and presented him with vel (a weapon) to slay the demons. Subramanya overcame the asura Surapadman (a demon) and in the war, his army was severely injured. Shiva came out as the healer Vaitheeswaran and cured the wounds.
