• Deep Cold Dispersal (Treating Winter Diseases in Summer): By applying warm herbal patches during peak summer when blood circulation is robust and pores are open, the therapy deeply penetrates acupoints to thoroughly dispel rooted, chronic pathogenic Cold.

• Immune System Modulation: Clinical research indicates that these herbal patches help regulate immune responses (such as lowering serum IgE levels), proactively building a protective shield before the transition into autumn and winter.

• Respiratory & Meridian Relief: By warming and nourishing the Qi of the Lung, Spleen, and Kidney meridians, the therapy effectively reduces the frequency and severity of seasonal allergies, chronic coughs, and asthma flare-ups.

The "San Fu" days represent the hottest 40 days of the year, a period when the body's Yang energy peaks and metabolic rates are at their highest. Applying Sanfu herbal patches during this window capitalizes on nature's heat to maximize the effects of "borrowing summer heat to expel internal cold."

The standard protocol recommends 3 to 4 sessions (Initial Fu, Middle Fu, Strengthening Session, and Final Fu). Undergoing this regimen consistently across three consecutive summers creates a cumulative, constitution-shifting effect, breaking the chronic cycle of winter colds and recurring allergies.

• Respiratory Issues: Individuals dealing with allergic rhinitis (seasonal allergies), frequent colds, chronic coughs, or asthma-prone constitutions.

• Deficiency-Cold Constitutions: Those who are highly sensitive to cold, constantly experience cold hands and feet, or suffer from chronic fatigue.

• Weak Digestive Systems: Individuals prone to diarrhea from cold foods, chronic stomach aches, or general Spleen and Stomach deficiency-cold.

• Cold-Pattern Gynecological Issues: Women experiencing menstrual cramps (dysmenorrhea) or a cold sensation in the lower abdomen before or during their period that improves with heat.

To ensure patient safety, Sanfu herbal patching is temporarily deferred or not recommended under the following conditions:

• Acute Stages of Infections: Currently running a fever, experiencing a sore throat due to a cold, or during an acute flare-up of a chronic illness.

• Skin Sensitivity: Presence of open wounds, skin ulcerations, or severe skin allergies at the application sites.

• Special Populations: Pregnant women and infants under 3 years old (due to tender skin that blisters easily).

• Heat-Pattern Constitutions: Individuals with Yin deficiency, with excess fire, or a "heat" constitution (frequent dry mouth, constipation, or prone to canker sores).
