TCM Syndrome Differentiation and Treatment for Frostbite
Frostbite is a common skin condition in cold seasons, affecting people of all ages, though more prevalent in women and children. It typically improves in spring and recurs in winter, commonly occurring on exposed areas like fingers and earlobes, and on parts with poor circulation such as heels and toes. During frostbite, the skin appears pale and swollen, feels icy to touch, and is accompanied by burning pain and itching—itching intensifies when warmed.
Frostbite often causes intense itching when warming up, disturbing concentration, work, and rest. Topical herbal fumigation and washing offer excellent therapeutic effects: 12g each of Angelica, Red Peony Root, Safflower, and Fine-leaf Ginger, 10g each of Wind-Protecting Herb, Schizonepeta, Cinnamon Twig, and Mugwort, 15g of Frankincense, 30g of Fresh Ginger, 10g of Licorice, and 30g of Alum. Add sufficient water, boil for 5–10 minutes, pour into a basin, fumigate and soak hands and feet. Use once daily, twice per day, each session about 20 minutes. Reuse the same decoction by adding water and reheating. Mild cases recover in 2–3 days; severe cases in 5–7 days.
Since the ears are difficult to fumigate, topical application is preferable: 50g each of Raw Aconite, Raw Kudzu, and Cinnamon Twig, 40g of Gypsum, 20g each of Fine-leaf Ginger and Safflower, 15g of Camphor. Soak all herbs in 1000ml of 60% alcohol, seal tightly for one week, filter and collect the liquid. Apply with cotton swab twice daily, 5 minutes each time.
Frostbite mainly results from insufficient yang energy in the body, leading to stagnation of qi and blood after cold exposure, depriving the skin of nourishment. To prevent frostbite in cold weather: first, increase physical exercise (to strengthen constitution), develop habits of washing face and hands with cold water (to enhance cold resistance), and soaking feet in hot water (to improve circulation). Second, keep warm and protect against freezing, frequently massaging vulnerable areas. After exposure to cold, avoid sudden heating (especially intense fire), instead use warm water immersion or warm wet towels to gradually restore local temperature, helping dissipate stasis and prevent frostbite.
