Small Fennel Fruit — Classic Formulas
Xiao Hui Xiang · Fructus Foeniculi
Primary Actions
- Warms the Liver and Kidney and dispels cold - Xiao Hui Xiang is the classical TCM medicinal fennel seed for cold-type lower abdominal pain and cramping.
- Moves qi and alleviates pain - it is used for hernia-type discomfort, menstrual cold pain, and stagnation in the lower burner.
- Harmonizes the Stomach - it also helps nausea, poor appetite, and cold-digestive discomfort when the middle burner lacks warmth.
Classic Formulas
- Tian Tai Wu Yao San - an important lower-abdominal cold and qi-stagnation formula that illustrates Xiao Hui Xiang's pain-relieving role.
- Nuan Gan Jian - warming-Liver formula that uses Xiao Hui Xiang when cold contracts the lower burner.
- Smaller digestive and menstrual formulas pair Xiao Hui Xiang with Gao Liang Jiang, Wu Zhu Yu, or Yan Hu Suo when cold and pain are tightly linked.
Classical Text References
- Traditional herbology classifies Xiao Hui Xiang as a warm acrid seed that enters the Liver, Kidney, Spleen, and Stomach.
- Its classical niche is colder, lower, and more pain-focused than many ordinary kitchen spice uses would suggest.
- It is preferred when cold-induced cramping and stagnation dominate rather than damp-heat or food-heat patterns.
