Can processed Cornus officinalis (Shanzhuyu) be taken long-term?

Whether prepared Cornus officinalis (Zhi Shan Zhu Yu) can be taken long-term mainly depends on the individual's specific condition. For individuals with weak constitution or kidney deficiency, long-term moderate use may be followed under medical advice. However, for those with a hot constitution or excessive internal heat, long-term consumption is not recommended. Detailed explanations are as follows: Prepared Cornus officinalis has functions including nourishing the liver and kidneys, consolidating essence, and reducing perspiration. It can be used to balance both yin and yang of the liver and kidneys, help maintain tendons and bones, assist in alleviating symptoms such as frequent and urgent urination caused by kidney deficiency, and has the function of strengthening the spleen and nourishing stomach qi, thus promoting harmonious digestion and absorption. For individuals with weak constitutions, especially those with kidney deficiency, due to its effects of nourishing the liver and kidneys and consolidating essence while reducing urination, it may be taken long-term in moderate amounts under the guidance of a TCM practitioner to achieve the purpose of body regulation. However, for individuals with a hot constitution or excessive internal heat, long-term use of prepared Cornus officinalis might exacerbate symptoms of excessive internal heat, such as dry mouth, thirst, and constipation. In addition, some individuals may be allergic to certain components in prepared Cornus officinalis; long-term consumption might trigger allergic reactions such as skin itching and swelling. Therefore, before taking prepared Cornus officinalis, it is recommended to consult professional physicians or TCM practitioners to understand your constitution and medication needs, ensuring the safety and effectiveness of the medication. In daily life, maintaining a healthy lifestyle with balanced nutrition and appropriate exercise is also recommended to help maintain overall health.
