Can Lianhua Qingwen Granules treat yellow nasal discharge?
Generally, Lianhua Qingwen Granules can help alleviate yellow nasal discharge caused by heat-toxin attacking the lungs, but it is less effective for cases due to wind-cold感冒 or bacterial infections. If in doubt, it is advisable to consult a healthcare professional in advance. Detailed analysis is as follows:

If yellow nasal discharge is accompanied by symptoms of heat-toxin attacking the lungs—such as fever, sore throat, cough, and yellow, thick phlegm—Lianhua Qingwen Granules may be effective. Containing ingredients like Forsythia suspensa (Lianqiao) and Lonicera japonica (Jinyinhua), this formula clears away epidemic toxins, resolves toxicity, and promotes lung function to relieve heat. It helps reduce mucosal inflammation caused by heat-toxin, decreases the production of yellow nasal discharge, and alleviates associated discomfort.
However, if yellow nasal discharge results from wind-cold感冒, accompanied by chills, absence of sweating, headache, and white, watery phlegm, or is due to bacterial infection with symptoms such as large amounts of nasal discharge, severe nasal congestion, and persistent fever, Lianhua Qingwen Granules are generally ineffective. In these cases, targeted treatments such as wind-dispersing cold-relieving medications or antibiotics are required. Using this product inappropriately may delay proper treatment.
Before using Lianhua Qingwen Granules, it's important to clearly identify the type of symptoms and take the recommended dosage—do not exceed the suggested amount. If symptoms do not improve or worsen after three days of use, seek medical attention promptly to adjust the treatment plan and avoid delaying recovery.
