Rue (Ruta graveolens) has a long history of traditional use in herbal medicine, particularly in Mediterranean and European folk practices. Historically, rue was considered beneficial for eye health, with mentions dating back to ancient Greece and Rome. For example, the Roman writer Pliny the Elder and the Greek physician Dioscorides noted its use for improving vision and treating eye ailments. In the Middle Ages, rue was sometimes included in herbal remedies for eye strain or visual disturbances, often in the form of topical applications or eye washes.

However, modern scientific validation for rue’s efficacy in supporting the eye or visual system is lacking. There are very limited contemporary studies investigating rue’s effects on eye health, and the few that do exist focus more on its general antioxidant or anti-inflammatory properties rather than direct ophthalmic benefits. Moreover, rue contains furanocoumarins, which can be toxic and cause photosensitivity or dermatitis, raising safety concerns for both internal and topical use.

In summary, rue’s association with eye health is rooted in historical tradition rather than supported by robust scientific evidence. Modern herbalists and clinicians generally do not recommend rue specifically for eye support due to insufficient evidence and potential risks.
