Fennel, the spice that warms the belly
Xiao Hui Xiang is “the little fragrance of Hui”: little, to distinguish it from the big one, star anise, which is something else entirely. What we call fennel seed is in fact the dried fruit of Foeniculum vulgare, a tall Mediterranean umbellifer with feathery foliage and golden-yellow umbels. China officially lists it as both a food and a herb of its pharmacopoeia: northern China has used it for centuries in dumplings, braised meats and pastries. Its benchmark origins are Inner Mongolia and Shanxi, and the Ben Cao Gang Mu held that of Ningxia to be the finest. A good fruit is cylindrical, with five prominent ridges and a clean, aniseed scent.
Warming the Middle, restoring Qi’s liveliness
In Traditional Chinese Medicine, fennel is warm, with a single flavour, pungent, which moves and disperses; it warms without the vehemence of the great hot plants. It is also aromatic, and tradition holds aroma to be what penetrates and awakens a sluggish Middle. Associated with the Spleen and the Stomach, it sets Qi moving again in a Middle Burner slowed by Cold and dispels fullness: that is why the same seed is both a kitchen spice and an apothecary herb. One classical text defines it in six characters: a substance that warms the Middle and restores Qi’s liveliness.
Cold in the lower abdomen
Its two other meridians, the Liver and the Kidney, direct it towards the lower body. Tradition teaches that Cold contracts: it knots the meridian, and Qi comes to a halt. Fennel warms what has tightened, and movement resumes; this is its most characteristic use. With Wu Yao, it forms the classic pair for knotted Cold in the lower abdomen. Not to be confused with star anise, similar in aroma but botanically unrelated: little fennel is better at moving Stomach Qi. Modern research is looking in particular at trans-anethole.
