Can you still drink expired胖大海菊花茶 (Pangdahai chrysanthemum tea)?

Generally speaking, expired puhuangmei chrysanthemum tea should not be consumed. The detailed explanation is as follows:

It is not recommended to drink puhuangmei chrysanthemum tea after it has expired. Once past its expiration date, food products such as chrysanthemum tea and puhuangmei (Sterculia lychnophora) may undergo quality deterioration, losing their original medicinal value and flavor. They may also develop molds, bacteria, and other microorganisms, which could negatively affect health if ingested. In addition, the nutritional components in expired tea may have degraded, making it ineffective for achieving the desired health benefits. Therefore, to ensure health and safety, one should avoid drinking expired puhuangmei chrysanthemum tea and instead use fresh tea leaves and herbs for brewing.

Fresh, unexpired puhuangmei chrysanthemum tea can help lower blood pressure, soothe the throat, and relieve phlegm. It is commonly used to alleviate symptoms such as sore throat, hoarseness, red eyes, and headaches. However, it should be noted that puhuangmei is cool in nature and chrysanthemum is cold in nature. Consuming excessive amounts at once may lead to abdominal pain, diarrhea, or other discomforts; therefore, moderate consumption is advised.

In daily life, it's important to maintain a diverse diet and consume more fresh fruits and vegetables such as spinach, apples, and grapes, which can help enhance the body's immune system.
