Can I soak only Cornus officinalis (Shanzhuyu)?

Generally, Cornus officinalis (Shanzhuyu) can be used alone for泡tea, but it should be taken under the guidance of a licensed Traditional Chinese Medicine (TCM) practitioner. Detailed analysis is as follows:

Cornus officinalis is a commonly used traditional Chinese herb that has functions of nourishing the liver and kidneys, and astringing to relieve symptoms such as excessive sweating or diarrhea. If one only needs to simply utilize its medicinal effects, it is acceptable to use only Cornus officinalis for泡tea under the guidance of a TCM practitioner. In this case, steeping it in hot water allows its active ingredients to dissolve in the water, thereby achieving certain therapeutic or health benefits.

However,泡Cornus officinalis in water is not suitable for everyone. It is slightly warm in nature and has an acidic and astringent taste. Individuals with damp-heat or excess internal heat constitutions—for example, those experiencing symptoms such as bitter taste in the mouth, bad breath, a yellow and greasy tongue coating, or sticky stools—may find their symptoms worsened after consumption. Additionally, long-term or excessive consumption may cause gastrointestinal discomfort, such as nausea and vomiting. Therefore, it is recommended to consult a professional TCM practitioner or pharmacist before using Cornus officinalis to ensure safety and effectiveness.

While using traditional Chinese medicinal herbs, it is important to cultivate healthy lifestyle habits, maintain a balanced diet, and avoid excessive fatigue, in order to fully maximize the therapeutic effects and promote recovery.
