Roasted Radish Seed, Ginger and Tangerine Cake Tea

Why people make this tea

Not all coughs are the same. Traditional Chinese food therapy draws a clear distinction between a cough caused by heat patterns — with yellow, thick, sticky phlegm — and one caused by cold, where the phlegm is thin, white, and watery, and the person feels chilled and congested. This tea is designed specifically for the second type: the wind-cold cough.

Radish seeds (lai fu zi) are the seeds of the common radish, and have long been used in Chinese herbal cooking as a phlegm-dissolving, digestion-supporting ingredient. The raw seed has a strong upward-rushing action that can cause nausea or vomiting, so dry-roasting transforms this: roasted radish seeds (炒莱菔子, chao lai fu zi) work downward and inward, reducing phlegm and settling the chest without causing discomfort. Modern research has confirmed antimicrobial activity against a range of bacteria, as well as mild blood-pressure-lowering effects.

Fresh ginger warms the lungs from within, helping to dissolve cold phlegm and restore warmth to a chest that feels tight and congested. Tangerine cake adds throat-soothing sweetness and rounds out the blend.

Method

1. Chop the tangerine cake finely.
2. Combine all ingredients in a small pot with 1.2 L of water.
3. Bring to a boil, then reduce heat and simmer for 30 minutes until reduced to about 600 ml.
4. Drink warm. The tangerine cake provides enough sweetness — no sugar needed.

Nourilo’s Tips

Tangerine cake is already very sweet, so there is no need to add sugar. This tea is particularly well-suited to elderly people with chronic bronchitis who are not strong enough to tolerate the raw radish seed. For younger children (around 2 years old), the dose can be given, but reduce the roasted radish seed quantity to 11 g.

Remember: if someone is taking any form of qi-tonifying supplement — ginseng, codonopsis, astragalus, or similar — they should stop or pause those while using this tea, as the two work in opposing directions.
