The Sree Dhanwanthari Temple at Nelluvai is one of India's most prominent and ancient temples dedicated to Lord Dhanwanthari. According to legend, the temple's idol was installed by the Ashwini Devas and was the same one worshipped by Sri Vasudevar in the Dwapara Yuga. Hence, it is inferred that the temple's origin dates back more than 5000 years.
