Liquidity
One of the 20 universal attributes representing the liquid, diluted, less concentrated quality
Liquid Quality (Drava)
Drava (liquid) is one of the 20 universal attributes in Ayurveda, representing the quality of being diluted, less concentrated, and fluid. It is the opposite of sandra (dense). The liquid quality increases pitta and kapha while decreasing vata.
The distinction between drava and sandra is one of concentration: water is drava — liquid and diluted — but if salt is continually added until it stops dissolving, the resulting highly concentrated salty water becomes sandra (dense). Kapha embodies both the dense, liquid, and salty qualities.
Drava dissolves and liquefies substances in the body. The liquid quality promotes salivation, compassion, and cohesiveness. However, excessive intake of water will cause water retention and increase kapha in the system.
