What are the indications for applying Sanfu patches?

Sanfu贴 (Sanfu Plaster) is suitable for chronic respiratory conditions, cold-damp disorders of the bones and joints, spleen-stomach deficiency-cold syndromes, uterine coldness-related gynecological discomfort, and constitutional weakness predisposing to recurrent common colds. By harnessing the abundant yang energy of summer, it helps dispel internal cold and dampness, thereby regulating various chronic deficiency-cold conditions. Its use must follow professional medical guidance. When underlying health conditions are complex, patients should first consult a healthcare provider to determine suitability for application.

1. Chronic Respiratory Conditions: Persistent cough, asthma, and chronic rhinitis often stem from lung deficiency-cold. Sanfu Plaster warms and unblocks the lung meridians, expelling accumulated cold from the lungs and reducing the frequency of seasonal coughing, wheezing, nasal congestion, and rhinorrhea.

2. Cold-Damp Disorders of Bones and Joints: Neck, shoulder, lumbar, and leg pain caused by wind-cold-damp bi syndrome—worsening upon exposure to cold or chilling—can be alleviated through Sanfu Plaster application. It warms and unblocks the meridians, dispels cold and dampness, relieves joint stiffness and soreness, and enhances comfort and mobility of the limbs.

3. Spleen-Stomach Deficiency-Cold Syndromes: Individuals who consistently experience abdominal cold sensitivity, loose stools, or abdominal pain after consuming raw or cold foods benefit from the warming and tonifying effects of the plaster on spleen-stomach yang qi. This improves impaired digestive function and alleviates deficiency-cold symptoms such as abdominal distension, diarrhea, and poor appetite.

4. Uterine Coldness-Related Gynecological Discomfort: Women experiencing menstrual cramps, clotted menstrual blood, or persistent lower abdominal coldness may benefit from Sanfu Plaster. Its therapeutic action warms and disperses cold from the lower jiao, promotes smooth flow of qi and blood in the uterus, alleviates cold-induced menstrual pain, and improves blood stasis and qi stagnation.

5. Constitutional Weakness with Recurrent Common Colds: For individuals with deficient zheng qi (vital qi), aversion to cold, and frequent external pathogenic invasions during seasonal transitions, Sanfu Plaster helps warm and supplement yang qi, fortify defensive qi (wei qi), enhance the body’s resistance against cold pathogens, and reduce the incidence of colds.

After application, avoid cold water, icy beverages, and direct exposure to cold drafts for a short period. Limit intake of heavy, spicy foods, and drink moderate amounts of warm water to sustain the nurturing effect of summer’s abundant yang energy on deficiency-cold organs and tissues.
