Can eating Lao Xiang Huang cure cough?

Generally speaking, to a certain extent, consuming Lao Xiang Huang (aged preserved citrus peel) can help treat cough. The detailed explanation is as follows:

Lao Xiang Huang is made from pickled bergamot and contains ingredients such as hesperidin and volatile oils, which help regulate qi, resolve phlegm, moisturize the lungs, and relieve cough. It is suitable for alleviating mild cough caused by initial stages of colds due to exposure to cold or early bronchitis, especially when accompanied by excessive phlegm and throat discomfort. Its sweet and sour flavor with a hint of fragrance can stimulate secretion of respiratory mucosa, dilute phlegm, promote expectoration, and relieve throat discomfort. A small amount can be taken orally or steeped in water, allowing its active ingredients to work slowly on the respiratory tract.

Consumption of Lao Xiang Huang should be moderate—just 1–2 small pieces each time. Excessive intake may irritate the gastrointestinal tract and cause excess stomach acid. Pregnant women and children should consume only small amounts, and those with weak spleen and stomach should use it cautiously; it should not be taken on an empty stomach. If the cough is severe, lasts a long time, or is accompanied by symptoms such as fever or chest pain, Lao Xiang Huang alone will not suffice, and prompt medical attention is necessary. It should be stored sealed in a cool, dry place to prevent spoilage.
