Everything You Need to Know About Sanfu Plasters — A TCM Guide to Seasonal Healing
Share
What Are Sanfu Days?
Sanfu Days refer to the hottest period of the year in the Chinese lunar calendar, occurring between Minor Heat (Xiaoshu) and Beginning of Autumn (Liqiu). In Traditional Chinese Medicine (TCM), this period is considered a prime time for preventive treatment, especially for chronic cold-related conditions.
The 2025 Sanfu schedule is as follows:
- Pre-Sanfu (Yin Fu): July 10, 2025
- First Sanfu (Chu Fu): July 20, 2025
- Middle Sanfu (Zhong Fu): July 30, 2025
- Last Sanfu (Mo Fu): August 9, 2025
- Extra Sanfu (Strengthening Fu): August 19, 2025
During these days, the body's yang energy is at its peak, making it the ideal time to “open acupoints” and support the body's natural defenses through external herbal therapy.

🌿 What Are Sanfu Plasters and How Do They Work?
Also known as Tianjiu Therapy, Sanfu Plasters involve applying specially formulated herbal pastes to specific acupuncture points. The combination of transdermal herbal absorption and natural warmth during Sanfu days helps to:
- Unblock meridians
- Strengthen the functions of the spleen, lungs, and kidneys
- Warm yang and dispel internal cold
- Enhance the immune system
This method is especially effective for managing “winter diseases”—chronic conditions that tend to worsen in colder months—by treating them in advance during summer.
👥 Who Should Consider Sanfu Plaster Therapy?
Sanfu Plasters are suitable for individuals who experience:
- Frequent colds, nasal allergies, or asthma
- Joint pain, cold intolerance, or cold hands and feet
- Chronic diarrhea or weak digestion due to cold in the gastrointestinal system
- Irregular menstruation or menstrual pain
- Children who are physically weak, prone to sickness, or have poor appetite
- Post-illness weakness (e.g. recovering after COVID or flu)
⚠️ What If Redness or Blisters Occur?
Some people may experience mild allergic reactions, such as redness, burning, or blistering.
If this happens, remove the plaster immediately and treat the skin accordingly. For mild symptoms, you may apply Baoshutang Baofuling Compound Camphor Cream to soothe irritation. In severe cases, consult a doctor.

✅ Final Words
Sanfu Plaster Therapy is not just about “putting on a patch.”
It embodies the wisdom of Traditional Chinese Medicine by combining seasonal timing, individual constitution, and holistic care.
Take advantage of this golden healing window in summer to build a stronger foundation for your health in the months to come.
