Is Erchen Wan effective for chronic pharyngitis?

Generally speaking, whether Erchen Wan is effective for chronic pharyngitis depends on the specific circumstances. If chronic pharyngitis is caused by internal obstruction due to phlegm-dampness, Erchen Wan may have some therapeutic effect. However, if the condition is due to other syndrome patterns, its effectiveness is usually limited. A detailed analysis is as follows:

If chronic pharyngitis presents with symptoms such as sticky phlegm in the throat that is difficult to cough up, along with a sensation of a foreign body in the throat, chest tightness, and a white, greasy tongue coating—indicative of internal obstruction by phlegm-dampness—Erchen Wan's functions of drying dampness, resolving phlegm, regulating qi, and harmonizing the stomach may help eliminate phlegm-dampness and alleviate throat discomfort, thus serving as an adjunctive treatment.

If chronic pharyngitis is caused by yin deficiency with fire hyperactivity or invasion by wind-heat, manifesting as symptoms such as dryness, burning sensation in the throat, sore throat, a red tongue with little moisture, Erchen Wan is not appropriate. Because it primarily targets phlegm-dampness syndromes, it cannot relieve throat symptoms caused by yin deficiency or wind-heat, and inappropriate use may fail to improve the condition.

In daily life, patients with chronic pharyngitis should pay attention to keeping the throat moist, drinking plenty of water, avoiding excessive voice use, and minimizing exposure to dust and irritating gases. Diet-wise, they should reduce intake of spicy and sweet greasy foods and may appropriately consume throat-soothing ingredients such as pears and lilies. Maintaining a regular作息 (作息 should be translated as "routine" or "作息 habits")作息 habits also helps alleviate throat discomfort and maintain throat health.
