Cinnamomun camphora is an important species for afforestation in southern China and is widely used in landscaping. To explore the seasonal dynamics of the volatile organic compounds (VOCs) released from Cinnamomun camphora forests and the adjuvant therapeutic effect of forest bathing on elderly patients with hypertension (HTN), the components and relative contents of VOCs released by a Cinnamomun camphora forest were analysed, and the blood pressure and inflammation of elderly patients with HTN experiencing forest bathing were studied. Variations in the components and relative contents of VOCs released by the Cinnamomun camphora forest were detected among the seasons, and the alkanes varied more widely than the other kinds of VOCs. The relative contents of alkanes and organic acids were greater than those of the other kinds of VOCs in spring and winter, while the VOCs released in autumn and summer contained higher proportions of terpenes. Forest bathing in Cinnamomun camphora forests in autumn, summer and spring had a high auxiliary regulatory effect on blood pressure and inflammation in elderly patients with HTN, which may be closely related to terpenes and negative oxygen ions. However, forest bathing in Cinnamomun camphora forests in winter was not conducive to the therapy of elderly patients with HTN. The results not only lay the foundation for research on the release of VOCs from Cinnamomun camphora forests but also provide a reference for studies on the influences of forest bathing on human health.

樟树是我国南方重要的造林树种，广泛用于园林绿化。为探讨樟树林释放挥发性有机化合物（VOCs）的季节动态及森林浴对老年高血压（HTN）的辅助治疗作用，对樟树林释放的VOCs成分及相对含量进行了分析。 ，并研究了经历森林浴的老年高血压患者的血压和炎症。樟树释放VOCs成分及相对含量的变化季节间检测到森林，并且烷烃的变化比其他种类的 VOCs 更广。春季和冬季烷烃和有机酸的相对含量高于其他种类的VOCs，而秋季和夏季释放的VOCs中萜烯的比例较高。秋、夏、春三季樟树森林浴对老年高血压患者的血压和炎症有较高的辅助调节作用，这可能与萜类和负氧离子密切相关。然而，冬季在樟树林中进行森林浴不利于老年高血压患者的治疗。研究结果不仅为研究 VOCs 的释放奠定了基础。香樟林也为研究森林浴对人体健康的影响提供了参考。
