The exact site of kloma is not defined but it’s the main controlling center for water regulation in the body. Acharya chakrapani described kloma as the site of thirst and mentioned that it is situated near the heart (hridyastha pipasa sthana).[Chakrapani on Cha. Sa. Vimana Sthana 05/08] Acharya Gangadhara described the site of kloma as the junction of throat and chest (Kantha urso sandhi). [Gangadhara on Cha. Sa. Vimana Sthana 05/08]
