Healthy saliva is usually clear or white. However, the color of saliva or phlegm (often mistakenly called spit) can vary and sometimes indicates an underlying health issue. Let's explore the different colors and their possible meanings.
Understanding Saliva and Phlegm
It's important to distinguish between saliva and phlegm. Saliva is produced in the mouth, while phlegm is mucus from the respiratory tract. While both might be expelled from the mouth, their colors and implications differ.
Healthy Saliva
As mentioned, healthy saliva is typically clear or slightly white and thin. A thick, white saliva could indicate oral thrush (oral candidiasis), a yeast infection. [Source: Jagwire]
