Can Yaowang tea and Cornus officinalis be consumed together?
Generally, Yaowang tea and Cornus officinalis (Shanzhuyu) are not recommended to be consumed together. The specific analysis is as follows:

Both Yaowang tea and Cornus officinalis possess certain astringent properties. Yaowang tea may be used in the treatment of diarrhea and dysentery, exerting effects of astringing the intestines and stopping diarrhea. Cornus officinalis has an acidic and astringent nature, which enables it to consolidate essence, reduce urination, and also astringe the intestines to stop diarrhea. It is commonly used for treating conditions such as spermatorrhea, nocturnal emission, enuresis, frequent urination, and prolonged diarrhea. When used together, their combined astringent effects may become excessively strong, potentially causing excessive intestinal constriction and adversely affecting normal excretory function.
Yaowang tea is warm in nature, as is Cornus officinalis, which is slightly warm. Consuming them together may enhance the body's internal heat. If it is necessary to use both of these herbs or ingredients simultaneously, it is advisable to first consult a professional physician or pharmacist to avoid indiscriminate combinations, ensuring both efficacy and safety. Additionally, if there is a history of allergy to either Yaowang tea or any component of Cornus officinalis, they should not be used together to prevent allergic reactions.
In daily life, maintaining a healthy lifestyle, balanced diet, and appropriate exercise can help support overall health.
