What causes external genital itching?

Patient's question:

Vulvar hyperpruritus

Doctor's answer:

Hello, vulvar pruritus refers to a symptom caused by various gynecological diseases, known in traditional Chinese medicine as "vulvar itching." The key to treating this condition lies in paying attention to menstrual hygiene, maintaining vulvar cleanliness, and promptly eliminating the cause—treating the root rather than the symptom leads to health.
Traditional Chinese Medicine Therapy:
Medicine Name: Tankejing
Usage: First, rinse the vulva with warm water. Then, take 0.2 grams of Tankejing powder and apply it to the itchy area. Insert 0.1 grams into the vagina. Use once daily. Discontinue use during menstruation. Pregnant women should use with caution. Avoid sexual activity during treatment. A 5-day course constitutes one treatment.
Effectiveness: The effective rate reaches 100% after 1–2 treatment courses.
