Is Chuanbei powder still effective after being stored for a year

Whether Chuanbei powder is effective after one year of storage depends on the storage conditions. If stored properly, it usually still has a certain medicinal effect. If it is damp or spoiled, it is not recommended to use it. Chuanbei powder is made from dried bulbs of the lily family plant Chuanbei mother, which has the effects of clearing heat, moistening the lungs, resolving phlegm, and stopping cough. It is commonly used for symptoms such as lung heat cough, dry cough, and low phlegm. Sichuan scallop powder is stored in a sealed, dark, cool and dry environment for one year, and usually does not significantly affect its active ingredients. According to traditional Chinese medicine theory, dried medicinal materials can be stored for a long time under suitable conditions, and the alkaloid active substances in Chuanbei powder are relatively stable. It is recommended to observe whether the powder clumps, changes color, or has a strange odor when using it. Loose texture, milky white color, and fragrant odor are preferred. If Chuanbei powder comes into contact with air and causes moisture absorption and mold growth, or is exposed to high temperature and humidity for a long time, its efficacy may be significantly reduced or even harmful substances may be produced. Damp Sichuan scallop powder may develop mold spots, sour taste, or clumping, and should not be continued to be taken in such cases. Traditional Chinese medicine materials may breed harmful microorganisms such as Aspergillus flavus after mold growth, and ingestion may cause gastrointestinal discomfort or liver damage. Before using Sichuan scallop powder that has been stored for a long time, it is recommended to consult a traditional Chinese medicine practitioner for quality identification. Daily storage can be placed in a glass jar with desiccant to avoid mixing with odorous items. Sichuan shellfish powder should be combined with snow pear, honey and other lung moistening ingredients to enhance the curative effect. Those who cough in cold weather or have spleen and stomach deficiency should use it carefully. If cough symptoms persist or worsen, seek medical attention promptly to determine the cause.
