Fennel Seeds (Xiao Hui Xiang): A Warming Herb for Digestion, Qi Flow, and Abdominal Comfort

Introduction

Fennel seeds, known as Xiao Hui Xiang (小茴香) in Traditional Chinese Medicine (TCM), are a fragrant, warming herb traditionally used to regulate qi, warm the interior, and alleviate abdominal pain. Their sweet and slightly pungent nature makes them ideal for relieving digestive discomfort, soothing menstrual cramps, and dispelling cold in the lower abdomen. Used both as a culinary spice and medicinal herb, fennel seeds bring warmth, movement, and comfort to the body.

What Are Fennel Seeds?

Xiao Hui Xiang refers to the dried seeds of Foeniculum vulgare, a hardy plant native to the Mediterranean but long integrated into Chinese herbal medicine. In TCM, fennel seeds are classified as acrid, warm, and entering the Liver, Kidney, Spleen, and Stomach meridians. Traditionally, they are used to move qi, disperse cold, relieve pain, and harmonize the Stomach. Their aromatic quality makes them a favorite in formulas for digestive complaints and cold-induced menstrual issues.
