Avicenna (980–1037 AD) and Nocturnal Itching: Exploring Gut-Skin Connection.

Avicenna's historical insights on digestive health and dermatological symptoms' interrelationship, mainly nocturnal itching, are examined here. In his Canon of Medicine, Avicenna explains a deep relationship between the digestive system and the skin, pointing out that effective waste elimination via the skin is vital for overall wellness. The discussion highlights the significant impact of nocturnal itching on patients with inflammatory skin conditions, such as atopic dermatitis, psoriasis, and chronic urticaria, in studying the roles of skin barrier function and hormonal fluctuations. Furthermore, modern scientific research on the gut-skin axis is integrated to illustrate the continued relevance of Avicenna's therapeutic recommendations, such as addressing internal imbalances, body cleansing, and topical therapies.
