Late-Harvest Silkworm Droppings … Classic Formulas
Wan Can Sha · Excrementum Bombycis Mori
Primary Actions
- Dispels wind-dampness and frees the collaterals in the same general herb family as Can Sha, especially for chronic joint pain, stiffness, and rheumatic discomfort.
- Harmonizes the middle and transforms turbid dampness for diarrhea, abdominal discomfort, and cramping when digestion is burdened by damp obstruction.
- Supports external-use traditions for itching, damp skin irritation, or warm compresses over painful areas.
Classic Formulas
- Can Shi Tang-style digestive formulas ... the same core family context shared with Can Sha.
- Warm bag, wash, or external applications ... especially when local dampness, itching, or aching dominates.
- Wind-damp combinations for chronic obstruction ... the practical lane for long-standing joint complaints.
Classical Text References
- Traditional sources treat Wan Can Sha as a recognized name within the Can Sha lineage rather than as a wholly distinct medicinal.
- Its actions remain the familiar Can Sha pattern ... dispelling wind-dampness and harmonizing the Stomach.
- Quality discussion centers more on harvest stage and processing than on any fundamentally different TCM nature.
