Sanfu Plasters represent a traditional Chinese medical therapy integrating acupuncture, meridian theory, and herbal medicine. By applying herbal compounds directly to specific acupoints, they achieve therapeutic and preventive effects. Though seemingly simple, repeated application requires careful attention to several key considerations. Below, we outline essential guidelines for using Sanfu Plasters.
Application Must Be "Tailored to the Condition"
Sanfu Plasters have clearly defined target users and should be selected cautiously based on individual constitutions and disease types. Even within the same disease category, different syndromes exist—such as cough and wheezing caused by cold phlegm invading the lungs, lung qi deficiency, or yin fluid depletion—each arising from distinct etiologies. Among these, Sanfu Plasters yield significant efficacy for cough and wheezing due to cold phlegm invading the lungs.
As a form of treating winter ailments in summer, TCM views winter diseases as conditions exacerbated or triggered by cold exposure—such as recurrent colds, COPD, asthma, and rhinitis—exhibiting distinct seasonal patterns. Individuals prone to these conditions often possess a cold-deficient constitution, typically presenting with pale complexions, cold hands and feet, aversion to wind and cold, and a preference for warmth.
While the Three-Fold Heat Plasters are effective for some individuals with a cold-deficient constitution, their efficacy is significantly reduced for those unsuitable for this treatment. Improper application without proper diagnosis may not only fail to treat the condition but could also lead to other health issues by overusing yang-enhancing substances, which may deplete yin fluids.He advises patients to consult a physician before application to understand their condition and constitution, ensuring appropriate selection and use of the treatment. During the application period, avoid raw, cold, spicy, and greasy foods, refrain from seafood, reduce physical activity to minimize sweating, and avoid prolonged exposure to direct fan drafts or excessively cool air-conditioned environments.
5 Essential Precautions for Applying Summer Heat Plasters
1. Strong reactions are normal.
Within 4–6 hours after application, some may experience prickling or itching—a natural response as the medication penetrates the skin. Others may develop redness, swelling, warmth, or pain.Approximately 1–5% of individuals may develop blisters. These reactions occur due to thorough absorption of the medication and acupoint sensitivity. Patients with blistering or intense reactions often experience unexpectedly strong therapeutic effects. To prevent infection, avoid scratching blisters. Small blisters may resolve on their own, while larger ones can be punctured with a sterilized needle to drain fluid, followed by application of antiseptic solution.
2. Maintain continuity.
Winter-prone illnesses may show minimal or no symptoms during summer, so treatment effects often become apparent only in winter. Patients who approach treatment with a "let's see" attitude may abandon therapy when immediate results are absent, leading to prolonged and difficult recovery.
3. Seize the optimal timing.
The Three-Fervent Days represent the peak of yang energy in the year. During this period, the pores at acupoints fully open, allowing medicinal properties to penetrate the body most effectively. Conversely, the Three-Nine Days of winter mark the coldest time of the year. Yang energy is stored internally, qi and blood circulation slows, skin becomes dry, and pores close.Applying patches to acupoints during these periods can warm yang, boost qi, strengthen the spleen, nourish the kidneys, benefit the lungs, dispel wind, and disperse cold. This achieves the effects of unblocking meridians, activating collaterals, and relieving pain. Clearly, "Three-Fold Summer Patches" and "Nine-Day Winter Patches" are undoubtedly important methods for enhancing patients' disease resistance and regulating the body's immunity.
Treating winter ailments in summer follows a three-fever cycle per treatment course. This year features an extra second fever period, hence the "reinforced moxibustion." Typically, three consecutive years—or three full courses—are required. Only consistent treatment maintains the medicine's efficacy, keeps meridians in a sustained state of stimulation, and ensures sustained momentum in expelling pathogenic factors. Moreover, treatment must be combined with proper care.Patients undergoing summer treatment for winter ailments should exercise restraint in daily habits even during the hottest days, avoiding excessive cooling and cooperating with therapy to achieve optimal results.
5. Maintain a light diet.
Eat radishes in the first heat, greens in the second, and buckwheat in the third; enjoy dumplings in the first heat, noodles in the second, and pancakes with eggs in the third.Dietary adjustments should focus on clearing the heart, preventing heatstroke, nourishing yin, and promoting fluid production. Avoid excessive consumption of rich, greasy, or sweet foods. Appropriate choices include mung beans, lotus seeds, coix seeds, vegetables, melons and fruits, lily bulbs, solomon's seal root, lean meat, eel, and duck meat.
