Should traditional Chinese medicine for treating urticaria be taken before or after meals?

Traditional Chinese herbal medicines for treating urticaria are generally taken after meals.

Etiology

Urticaria, commonly known as “wind rash” or “hives,” is a localized edematous reaction caused by dilation and increased permeability of small blood vessels in the skin and mucous membranes.

Treatment Protocol

Prescriptions used to treat urticaria typically aim to clear heat and eliminate toxins, release the exterior and dispel wind, or release the exterior and dispel cold. However, most herbs in these formulas are cold in nature and thus are generally unsuitable for administration on an empty stomach. Therefore, they are usually taken half an hour to one hour after meals—this helps prevent damage to the spleen and stomach.

Clinical Manifestations

The hallmark clinical feature is the appearance of wheals (urticarial lesions) on the skin. Patients often experience pruritus first, followed by the sudden onset of wheals, which may be bright red, pale, or skin-colored. A minority of patients develop erythematous, edematous plaques. Wheals vary in size and shape, and their onset is unpredictable.

Precautions

During treatment, medications must be taken regularly as prescribed; patients should not adjust dosages on their own. Daily diet should be light and bland, with minimal intake of greasy or spicy foods.
