Xiang Ru San香薷散
Mosla Powder
Ingredients3 herbs
Indications
Summer-cold damp: in the hot season the person seeks coolness or takes cold food, so wind-cold binds the exterior while damp encumbers the Spleen and Stomach. The season is hot, but the pattern is a closed surface.
Clinical Manifestations
- Summer chills and fever without sweating
- Heavy head and aching body in hot weather
- Abdominal pain with vomiting and diarrhoea in summer
- Chest and epigastric fullness after cold food in hot weather
- Gastroenteritis of the hot season with a white greasy coating
Health Categories
Modern Applications
Common adjustments
- Interior heat with thirst and irritability — add Huang Lian 黄连 — the classical Huang Lian Xiang Ru Yin
- Damp predominant with watery diarrhoea — add Fu Ling 茯苓 and Gan Cao 甘草
- Cramping in the calves — add Mu Gua 木瓜
- Qi deficiency with marked fatigue — add Ren Shen 人参 and Huang Qi 黄芪 per pattern
Contraindications
Not for — heat-stroke with high fever, drenching sweat and great thirst; opening the surface further in an already sweating patient is exactly the wrong move. Avoid in exterior deficiency with spontaneous sweating, and in yin deficiency with heat. Heat-stroke with confusion, collapse or absent sweating and very high temperature is a medical emergency, not a herbal one.
For licensed practitioners’ reference only — not a self-treatment guide.
Pregnancy
Use with caution in pregnancy — it opens the exterior by sweating and Hou Po moves qi downward; only short courses under practitioner supervision.
