Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Chinese orchid (Dendrobium spp.), known as "Shihu" in Traditional Chinese Medicine (TCM), has a long history of use in supporting the eyes and visual function. According to TCM theory, Dendrobium is believed to "nourish Yin," moisten dryness, and benefit the "eyes and vision," particularly in cases of eye fatigue, blurred vision, or dryness associated with Yin deficiency. Ancient texts like the "Shennong Bencao Jing" and later materia medica frequently mention Dendrobium's role in eye health, typically as part of formulas rather than as a stand-alone remedy.

However, scientific validation for these traditional uses is limited. Some modern pharmacological studies suggest that Dendrobium species contain polysaccharides and alkaloids with antioxidant and anti-inflammatory properties, which could theoretically benefit ocular health by reducing oxidative stress in eye tissues. Yet, there is a lack of direct clinical evidence or robust animal studies specifically linking Dendrobium extract to improvements in human eye conditions or visual acuity.

In summary, the use of Chinese orchid to support the eyes is primarily rooted in traditional practice with minimal scientific backing. Its evidence rating is low due to the absence of strong clinical trials or mechanistic studies directly relevant to eye health.
