Can I drink water infused with Cornus officinalis before bedtime?

Generally speaking, you can drink water infused with Cornus officinalis (Shanzhuyu) before bedtime, but this should be decided based on individual constitution and specific circumstances, and it should be consumed in moderation. Detailed explanation is as follows:

Cornus officinalis has the effect of nourishing the heart and calming the mind, and can help alleviate symptoms such as insomnia, frequent dreaming, and palpitations caused by insufficient liver and kidney function. It is suitable for individuals whose poor sleep quality is caused by yin deficiency of the liver and kidney. Cornus officinalis can nourish the liver and kidneys and may improve symptoms such as soreness and weakness in the waist and knees, dizziness, and tinnitus caused by liver and kidney deficiency.

However, please note that Cornus officinalis is warm in nature, and excessive consumption may worsen symptoms of internal damp-heat or excessive internal fire, such as dry mouth and throat, sore throat, and constipation. As Cornus officinalis has certain medicinal properties, pregnant and lactating women should use it cautiously to avoid adverse effects on the fetus or infant. Individuals allergic to Cornus officinalis should avoid consumption to prevent allergic reactions.

It is important to consume Cornus officinalis-infused water in moderation, as excessive intake may lead to physical discomfort, such as nausea, vomiting, and diarrhea. Before drinking Cornus officinalis-infused water, one should first understand their own body constitution, and consult a doctor or traditional Chinese medicine practitioner if necessary.
