Phlegm 痰
Phlegm is the thickened, obstructive form of trapped fluid — the concrete congestion that dampness produces when it concentrates.
Pinyin: Tan · Five Element: Earth · updated
Phlegm is what dampness becomes when it concentrates. Dampness is diffuse — a general heaviness. Phlegm is specific — congestion in a named place: the nose, the chest, the throat, or in the classical framework, nodules that form where fluids collect.
Chinese medicine also uses Phlegm as a metaphor for things that obstruct clear thinking, which is why a Phlegm-type pattern often shows up alongside foggy concentration or a sense of mental dullness. This is a classical reading rather than a biomedical claim, and it is worth holding as a description of experience rather than a mechanism.
Clearing phlegm means fluids have to move again. Warmth, movement that induces sweating, and reducing heavy cold food all help. Where phlegm is thick and fixed, the classical approach uses transforming herbs — those are practitioner territory, not self-prescription.

Patterns that often appear alongside this one
Phlegm and Dampness
Phlegm and dampness describe fluids that transform slowly, leaving the body heavy, coated and prone to congestion.
Food Stagnation
Food stagnation is the Spleen overwhelmed by more food than it can transform — the pattern behind most indigestion complaints.
Cold-Dampness
Cold-dampness is dampness that has been chilled — heaviness plus cold, which is what a weak digestion produces when cold food meets it.
Spleen
The Spleen governs transformation and transport — turning food and drink into usable energy, and moving what has been transformed.
Damp-Heat
Damp-heat combines sluggish fluid with excess heat — the pattern behind breakouts, burning sensations and a bitter taste.
Qi Stagnation
Qi stagnation is Qi that cannot move — emotion, breath and digestion pile up, and the pressure shows up in the chest, throat or mood.
