Can people with night sweats drink Cornus officinalis (Shanzhuyu)?
Generally, people who experience excessive sweating can take Cornus officinalis (Shanzhuyu), but the specific effects may vary from person to person, and attention should be paid to appropriate use and following medical advice. Detailed analysis is as follows:

Cornus officinalis has an astringent and anti-diaphoretic effect, which helps alleviate excessive sweating caused by physical weakness, such as spontaneous sweating and night sweating. Its medicinal property is warming and tonifying, capable of warming kidney yang, consolidating vital essence, and achieving the effect of stopping sweating. Deficiency of liver and kidney is one of the common causes of excessive sweating, and Cornus officinalis can nourish the liver and kidney, enhance liver and kidney function, and improve various symptoms caused by such deficiency, including excessive sweating.
Although Cornus officinalis can alleviate excessive sweating to some extent, it may not be effective for everyone. Each person's constitution and medical condition differ, and their response to medication may also vary. Cornus officinalis is mainly used for excessive sweating caused by kidney yang deficiency. For other causes such as yin deficiency with fire hyperactivity or internal accumulation of damp-heat, Cornus officinalis may not be effective. Therefore, it is important to identify the specific cause of excessive sweating before use.
Medical advice should be followed when using Cornus officinalis, with strict control of dosage. Overuse may lead to adverse reactions. It is recommended that individuals with excessive sweating first identify the cause and use the herb under a doctor's guidance. Additionally, attention should be paid to dosage control and monitoring bodily reactions to ensure the safety and effectiveness of the medication. If any discomfort occurs during use, the medication should be discontinued immediately and medical attention sought.
