Ping Wei San

Calm the Stomach Powder

Transform Damp • Regulate the Middle Jiao • Harmonize Digestion • Restore Appetite

Ping Wei San is one of the foundational classical formulas for resolving Damp accumulation in the Middle Jiao. Traditionally used when the Spleen and Stomach become overwhelmed by Dampness, it is especially valued for digestive patterns marked by heaviness, fullness, poor appetite, nausea, and sluggish transformation.

Unlike formulas that primarily tonify the Spleen, Ping Wei San first focuses on clearing the obstruction that prevents healthy digestion from occurring. By drying Damp, moving Qi, and harmonizing the Stomach, it creates a clearer environment for digestive function to recover.

When patients present with bloating, abdominal distention, nausea, loose stools, and a feeling of heaviness after eating, Ping Wei San is often one of the first formulas practitioners consider.

Beyond traditional digestive complaints, this formula has become a valuable clinical tool for modern presentations involving digestive stagnation, post-medication imbalance, and the “foggy” sensation that accompanies Damp accumulation.

Traditional Indications

• Damp stagnation in the Middle Jiao
• Nausea
• Bloating and abdominal distention
• Loss of appetite
• Loose stools
• Food stagnation
• Heavy sensation in the body
• Thick tongue coating
• Digestive sluggishness
• Spleen and Stomach disharmony

TCM Pattern

Damp Obstruction in the Middle Jiao with Qi Stagnation

Ping Wei San dries Damp, regulates Qi, harmonizes the Stomach, strengthens digestive transformation, and restores smooth movement through the Middle Burner.

Modern Clinical Applications

Many practitioners reach for Ping Wei San when supporting patients experiencing:

• Chronic bloating
• Nausea and poor digestion
• Post-antibiotic digestive disruption
• Food stagnation patterns
• Abdominal fullness after meals

Why Practitioners Keep Ping Wei San on the Shelf

Every practitioner eventually encounters the patient who says,

"My digestion feels stuck. I’m bloated, heavy, and food just seems to sit there."

That patient often reflects the classic Ping Wei San presentation.

Its strength comes from addressing one of the most common obstacles in Chinese medicine: Dampness interfering with the normal function of the Spleen and Stomach. Rather than immediately adding more tonics, Ping Wei San first clears what is blocking digestion so the body can better receive nourishment.

Practitioners frequently reach for Ping Wei San when supporting:

• Bloating and abdominal fullness
• Nausea after meals
• Poor appetite
• Loose stools with Damp signs
• Digestive stagnation
• Post-antibiotic digestive complaints
• Food accumulation patterns
• Heavy body sensation
• Foggy-headedness associated with Dampness

Because Urban Herbs tinctures are designed for blending, Ping Wei San becomes even more versatile when combined with formulas that strengthen the Spleen, resolve phlegm, support chronic deficiency, or address Cold-Damp presentations.

For many practitioners, it is the formula they consider when the digestive system needs clearing before it can be rebuilt.

One bottle. A timeless solution for transforming Damp and restoring Middle Jiao function.

Clinical Pearl

Ping Wei San is one of the classic formulas every practitioner associates with the phrase “clear the middle.” Its hallmark indication is a patient whose digestive system feels overwhelmed by Dampness—creating heaviness, fullness, sluggishness, and poor transformation.

Its brilliance lies in its practical simplicity. Cang Zhu dries Damp, Hou Po moves Qi and relieves fullness, Chen Pi regulates the Middle Jiao, and the supporting herbs harmonize the formula. Together, they create one of the most reliable approaches for clearing digestive obstruction and restoring normal Spleen and Stomach movement.

For practitioners, Ping Wei San remains an essential formula for the patient who needs the digestive terrain cleared before deeper rebuilding can begin.
