Can patients with nocturnal emission drink Cornus officinalis (Shanzhuyu)?
Generally speaking, patients with nocturnal emission can take Cornus officinalis (Shanzhuyu), but should do so in moderation. The detailed explanation is as follows:

Cornus officinalis has the effect of nourishing the liver and kidneys and promoting astringency and consolidation. According to traditional Chinese medicine (TCM) theory, nocturnal emission is often associated with kidney deficiency that fails to adequately consolidate semen. Through its function of nourishing and strengthening the liver and kidneys and its semen-consolidating effect, Cornus officinalis may help alleviate symptoms of nocturnal emission caused by kidney deficiency. With an acidic taste and slightly warm property, Cornus officinalis is moist in nature and enters the liver and kidney meridians, thereby nourishing the liver and kidneys, enhancing their functions, and improving symptoms such as nocturnal emission and enuresis caused by insufficiency of the liver and kidneys. Additionally, its astringent and consolidating effect also helps to retain semen and reduce urinary frequency, thus decreasing occurrences of nocturnal emission.
However, it should be noted that nocturnal emission has complex causes, including psychological factors, lifestyle habits, physical weakness, and other contributing factors. Therefore, when using Cornus officinalis for treatment, it is important to conduct syndrome differentiation based on the patient's specific condition and constitution to avoid indiscriminate medication. The dosage of Cornus officinalis should be determined according to the patient's specific condition and constitution, as excessive use may lead to adverse reactions.
In daily life, patients with nocturnal emission should also maintain healthy lifestyle habits and emotional well-being, avoiding excessive fatigue and emotional fluctuations to improve symptoms. If symptoms are severe or accompanied by other discomforts, timely medical consultation is recommended for professional diagnosis and treatment.
