Going back to the past, centuries ago, a family of Ayurveda Acharyas : Changethu family-has established on the fringes of Achankovil River. The legacy of Ayurveda has been bequeathed to Kanderar, by his guru Alathur Nambi, the Ashtavaidya, who was the storehouse of the covert combination of medicines for numerous ailments, has set out the family- Kalloorkkattu, which was renamed to Changethu by Vaidyan Narayana Kurup. Ever since Vaidyan Govindappillai and Vaidyakalanidhi Bhaskaran vaidyan have spearheaded the family. The wanton is now safe in the hands of Dr. C Sathish, Chief Physician, since 1989.
