Traditional Chinese medicine also utilized Camellia oil for its ability to nourish the skin and hair, promoting a healthy and youthful appearance (Seyis et al., 2019). Additionally, in Korea, the oil was often applied to the scalp to prevent hair loss and to maintain hair health, leveraging its rich content of oleic acid and other beneficial fatty acids (Seyis et al., 2019; Teixeira and Sousa, 2021). 6.2 Contemporary applications: current use in wellness, skincare, and dietary supplements In modern times, Camellia oleifera oil has found a variety of applications in wellness, skincare, and dietary supplements. Its high content of monounsaturated fatty acids, particularly oleic acid, makes it a popular ingredient in skincare products aimed at moisturizing and protecting the skin (Figure 3). The oil is often included in formulations for night creams, serums, and lotions due to its ability to penetrate deeply into the skin and provide long-lasting hydration (Seyis et al., 2019). Additionally, its antioxidant properties, attributed to the presence of polyphenols and Vitamin E, help in reducing oxidative stress and combating signs of aging (Seyis et al., 2019; Zhong et al., 2023). In the wellness industry, Camellia oleifera oil is used in aromatherapy and massage oils, where its light texture and pleasant aroma enhance relaxation and stress relief (Seyis et al., 2019). Furthermore, the oil is incorporated into dietary supplements for its potential health benefits, including boosting immunity and supporting cardiovascular health due to its favorable fatty acid profile (Seyis et al., 2019; Zhong et al., 2023). The oil's versatility extends to culinary uses as well, where it is valued for its mild flavor and high smoke point, making it suitable for cooking and salad dressings. Figure 3 (A).
