Bee products, such as honey and propolis, have a longstanding history in traditional medicine for treating various eye disorders, including conjunctivitis (commonly known as "pink eye"). In folk medicine across different cultures, honey has been topically applied to the eyes or used in eye drops to alleviate symptoms of redness, irritation, and infection. The rationale is based on honey's natural antibacterial and anti-inflammatory properties, as well as anecdotal reports of symptom relief.

Scientific evidence supporting the use of bee products for conjunctivitis is limited. A few in vitro and animal studies suggest that honey and propolis may inhibit certain bacteria and reduce inflammation, which are relevant to the pathophysiology of conjunctivitis. However, robust clinical trials in humans are lacking, and safety concerns (such as the risk of contamination or allergic reactions) have not been thoroughly addressed. Mainstream medical guidelines do not recommend bee products for conjunctivitis due to insufficient evidence and the availability of proven treatments.

In summary, the use of bee products for conjunctivitis is primarily justified by traditional practices rather than scientific validation. The evidence supporting their effectiveness is weak and largely anecdotal.
