Regarding dry mouth caused by heat disease: This condition arises because heat-toxin resides in the Spleen and Stomach. The mouth is the external manifestation of the Spleen. If there is accumulated heat within the Zang organs, body fluids (Jin-Ye) will become deficient and withered, thus causing dry mouth.
