Synopsis

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

Licorice (Glycyrrhiza glabra) has a long history of use in traditional medicine systems, particularly within Ayurveda and Traditional Chinese Medicine (TCM). In these systems, licorice is sometimes recommended for a variety of inflammatory and irritative conditions, including those affecting the eyes. Licorice is believed to have anti-inflammatory and soothing properties, which, in traditional theory, might help alleviate eye redness or bloodshot eyes, especially when caused by irritation or mild inflammation.

However, there is little to no direct scientific evidence validating the use of licorice for treating bloodshot eyes specifically. Most of the modern research on licorice focuses on its systemic anti-inflammatory and immunomodulatory effects, but these studies do not directly address ocular conditions such as conjunctival redness. Furthermore, there are no well-designed clinical trials or published pharmacological studies evaluating licorice (topically or systemically) for bloodshot eyes in humans. The traditional use, therefore, is not supported by robust scientific validation, and the evidence level for this application remains very low, primarily anecdotal or based on historical practice rather than clinical testing.
