Key Characteristic Symptoms
Other Associated Symptoms
Diagnostic Considerations
Chronic itchiness that worsens at night and pale tongue with a thin coating and a thin, wiry pulse are diagnostic signs.
Causes & Pathology
Common Causes
These can lead to a gradual depletion of Blood and Qi (vital energy), weakening the body's defenses against external pathogenic factors.
An insufficient intake of nutrients essential for blood production can lead to blood deficiency.
Prolonged exposure, especially in individuals with a Blood Deficiency constitution, can lead to this pattern.
Chronic stress or emotional disturbances can affect the Liver, which in TCM is closely related to the smooth flow of blood and qi throughout the body.
A compromised immune system, often linked with Blood and Qi Deficiency, makes the body more susceptible to external pathogens like Wind.
Pathological Mechanism
This pattern is characterized by chronic itchiness that worsens at night, potentially accompanied by a rash and flaking skin, resulting from long-term External Wind lodged in the body that has damaged the Blood, or occurring in individuals with a Blood-Deficient constitution who contract a Wind pathogen.
The pale tongue with a thin coating and a thin, wiry pulse are diagnostic signs. The focus of treatment in this pattern is to nourish the blood, moisten dryness, dispel wind, and alleviate itching, which is essential for conditions involving chronic itching skin disorders due to blood deficiency, contrasting with formulas that focus on dispelling wind-damp-heat toxins.
