Is it effective to take Xigua Shuang Qingyan Huanpian (Watermelon Frost Throat Soothing Lozenges) for pharyngitis?
In general, whether Watermelon Frost Throat Lozenges are effective for pharyngitis depends on the severity and underlying cause of the condition. They are usually effective for mild throat discomfort or chronic inflammation, but their effectiveness is limited in severe infections or cases with specific causes, which require targeted treatments. The detailed analysis is as follows:

If pharyngitis is in its early stage and only presents as dryness, mild sore throat, or slight hoarseness without significant pus-like sputum or fever, the cooling ingredients in Watermelon Frost Throat Lozenges can directly soothe the throat mucosa and reduce burning sensations. The herbal components may also help alleviate inflammation. Symptoms can improve shortly after dissolving the lozenge in the mouth, and the effect can be enhanced by drinking plenty of water.
However, if pharyngitis is caused by bacterial infection—accompanied by severe sore throat, tonsillar abscess, or fever—or results from specific conditions such as allergies or gastroesophageal reflux, Watermelon Frost Throat Lozenges can only temporarily relieve surface symptoms and cannot eliminate the root cause.
Daily precautions include avoiding excessive voice use and speaking at lower volumes; maintaining a light diet, avoiding spicy or hot foods to reduce throat irritation; drinking plenty of warm water to keep mucous membranes moist; using a humidifier indoors to maintain proper humidity; quitting smoking and limiting alcohol consumption. Combining these measures with the use of throat lozenges can better promote recovery from throat inflammation.
