gargle, rinse mouth
漱 centers on cleansing the mouth by swishing liquid: gargling or rinsing the mouth.
漱 combines 氵 (water) with 欶, which likely contributes the sound and the idea of drawing in or sucking, together suggesting rinsing with water.
Water 氵 on the left and 欶 on the right, which looks like a person 欠 with a mouth 口 and a tree 木, can be imagined as someone using water from a wooden bucket to rinse their mouth.
For ソウ, picture rinsing your mouth with a soothing sound: so -> ソウ, as the water swishes and cleans.
