Oriental arborvitae (Platycladus orientalis, also known as Biota orientalis or Thuja orientalis) has a long history of use in traditional Chinese medicine (TCM). In classical TCM texts, its seeds (often called Bai Zi Ren) are described as nourishing the heart, calming the spirit, and moistening the intestines. Occasionally, certain TCM sources mention its utility in formulas intended to benefit eye health, often in the context of treating blurred vision or dryness, which is attributed to deficiencies in internal organs such as the liver and kidney that are believed to "nourish the eyes" in TCM theory. However, there is little direct historical documentation that specifically links oriental arborvitae to the treatment of severe eye diseases or visual impairment. Furthermore, modern scientific research is scant regarding the direct effects of oriental arborvitae on eye health. Most available studies focus on its sedative, anti-inflammatory, and antioxidant properties, which, while potentially beneficial in a general sense, do not directly validate its use for eye conditions. Thus, while its use for eye problems is based primarily on traditional beliefs and theoretical frameworks, there is minimal scientific evidence to support its efficacy for this specific purpose.
