This is one of the five patterns of the Blood level, the fourth and last level of the Four Levels theory. This means this is a very serious pattern where an External Pathogen has penetrated deeply within the body.
At this level, the Heat had reached the Blood and is agitating it, much like heat makes water boil. This makes the Blood go out of the vessels, which is visible via various bleeding symptoms.
Heat in the Blood also disturbs the Mind since the Heart governs Blood and houses the Mind at the same time. This gives rise to symptoms such as mental restlessness and manic behavior.
Precursor patterns: Heat victorious agitating Blood can derive from Heat in Pericardium Heat in Nutritive Qi level
External pathogenic factor: The main original cause of Heat in Nutritive Qi level is an Exterior Pathogenic Factor (typically Wind-Heat) that has invaded the Interior and progressed to this level.
Diagnosing a pattern in Chinese Medicine is no easy feat and should be left to professional practitioners. In particular one has to know how to differentiate between different types of pulses and tongue coatings, shapes and colors as well as learn to read from a long list of seemingly unrelated symptoms.
