Rating (out of 5): 1

Oriental arborvitae (Platycladus orientalis), also known as Chinese thuja or biota, has a long history of use in traditional Chinese medicine. The leaves, seeds, and sometimes cones of the plant have been employed for various purposes, including promoting hair growth, stopping bleeding, and treating burns or skin irritations. In the context of sunburn, the application of preparations made from the leaves is mentioned in some traditional pharmacopeias and herbal texts, where it is believed to "clear heat" and "detoxify," which are traditional concepts associated with reducing inflammation or soothing damaged skin. However, robust scientific studies specifically validating its efficacy for sunburn are lacking, and most references to its use for this purpose are anecdotal or based on historical practice rather than modern clinical research. Some laboratory studies suggest that extracts of Platycladus orientalis have anti-inflammatory and antioxidant properties, which could theoretically support skin healing, but these findings have not been directly linked to sunburn treatment in clinical settings. Thus, its use for sunburn is primarily justified by tradition, and the evidence supporting its efficacy is limited.
