Pruritus
AliasPruritus sicca
Traditional Chinese Medicine Definition
In traditional Chinese medicine, pruritus is known as "wind itching," a condition categorized under dermatological diseases. According to the classical text "Internal Medicine in Traditional Chinese Medicine," it is described as: "Wind itching is characterized by intolerable itching of the skin, relentless scratching, bleeding upon scratching, dry skin, and may be accompanied by symptoms such as restlessness and insomnia." This condition is often attributed to the invasion of wind pathogen, internal heat, and malnutrition of the skin.
In clinical practice of traditional Chinese medicine, the core pathogenesis of pruritus is the invasion of wind and internal heat. Common triggers include irregular diet, emotional disturbances, and improper balance of work and rest. During diagnosis, attention should be paid to the following key points:
1. Cold and heat, deficiency and excess: Wind-heat syndrome presents with intermittent exacerbation of itching, worse upon exposure to heat; blood deficiency and liver hyperactivity syndrome is characterized by itching predominantly at night and dry skin.
2. Key points for differentiation: Observe the onset time, intensity of itching, and accompanying symptoms.
Overall treatment approach: In clinical practice, the treatment of pruritus in traditional Chinese medicine often focuses on expelling wind and clearing heat, nourishing blood and calming the liver, and removing wind and moistening dryness. By adjusting the internal and external environment of the body, restoring the balance of Qi and blood, the aim is to alleviate itching. Traditional Chinese medicine believes that the adjustment should be tailored to the specific constitution and condition of the patient, utilizing a comprehensive approach that includes internal herbal medicine, external applications, and therapies such as acupuncture and cupping.
