Chief Minister Oommen Chandy will officially inaugurate the GAF on January 31, organising committee members of the GAF said.
"The conclave is a discussion on promoting Ayurveda," Dr Praveen, an organising committee member told PTI.
Some 5,000 delegates, including 400 from abroad, will participate in the GAF in which about 500 firms will exhibit their products, the members told reporters here last evening.
The previous two events held at Kochi in 2012 and at Thiruvananthapuram in 2014 has made GAF, considered one of the largest biennial events of the ayurvedic fraternity, as an internally recognised festival.
