Fennel for cold, cramping period pain 小茴香温经

Women's Health 女性调理 traditional evidence
What the evidence says:
The 药典 indication for 小茴香 includes dysmenorrhoea from cold and cold lower-abdominal pain. Traditional use — the app is not claiming an independently verified effect on period pain. A heat pack has better evidence than the tea.

How to make it

Lightly crush 3–6 g fennel seed, steep covered in just-boiled water 10 min, drink warm. Traditionally taken with a hot-water bottle on the lower abdomen, which is the part that actually has trial support.

Why it works

Very safe as a culinary spice at these amounts.

Classical source

小茴香 is not in the Shennong Bencao Jing; it enters the Chinese materia medica later.

Cautions: Warming — avoid excess with heat signs or yin deficiency. Period pain that is new, worsening, or severe enough to stop you functioning should be assessed — endometriosis is commonly missed and averages years to diagnosis.
