If you frequently suffer from cold hands and feet that never seem to warm up, neck and shoulder pain, aching limbs, or an aversion to cold, these conditions are often caused by "cold pathogens" invading our meridians and blood vessels. In Traditional Chinese Medicine (TCM), cold is characterized by "contraction and pulling." Cold pathogens cause our meridians and vessels to constrict, leading to poor circulation and stagnation of Qi and blood. When blood cannot nourish the meridians and muscles, and fails to reach the extremities, pain occurs—as the TCM saying goes, "where there is obstruction, there is pain." Today, I would like to share a cold-dispelling formula from the *Treatise on Febrile Diseases* (Shanghan Lun) called Danggui Sini Decoction. It is designed to warm the meridians, dispel cold, nourish the blood, and unblock the vessels.

The formula consists of Danggui (Angelica sinensis), Guizhi (Cinnamon twig), Shaoyao (Peony root), Xixin (Asarum), Tongcao (Medulla Tetrapanacis), Zhi Gancao (Honey-fried Licorice root), and Dazao (Jujube). This remedy not only uses acrid and warm properties to activate Yang, but also promotes and tonifies blood while providing a soothing and moisturizing effect. While its medicinal properties are not overly aggressive, it effectively activates blood circulation and unblocks the vessels. It is highly suitable for those with cold limbs, stomach chills, and localized cold pain caused by insufficient Yang energy and poorly nourished blood vessels.

A reminder to everyone: Traditional Chinese Medicine requires syndrome differentiation. If needed, please consult a professional physician for timely diagnosis, treatment, and conditioning.
