Synopsis

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

Spanish Needle (Bidens pilosa) is an herb traditionally used in various folk medicines, particularly in tropical and subtropical regions. Its use for supporting eye health is primarily rooted in traditional practices rather than strong scientific validation. In some cultures, infusions or extracts of Spanish Needle have been used as eyewashes or remedies for eye conditions such as conjunctivitis and irritation. These uses are mostly anecdotal and passed down through generations, with very limited documentation in ethnobotanical records. Scientific research on Bidens pilosa has focused on its anti-inflammatory, antimicrobial, and antioxidant properties. While these properties theoretically could benefit eye health by reducing inflammation or fighting infection, direct clinical studies evaluating Spanish Needle specifically for eye conditions in humans are lacking. A few in vitro and animal studies suggest general antioxidant and anti-inflammatory effects, but they do not provide robust or targeted evidence for efficacy in treating or supporting the eyes. Therefore, while there is some traditional use of Spanish Needle for eye health, and while its general pharmacological actions might be beneficial, there is insufficient scientific evidence to recommend it specifically for eye support. The rating reflects the predominance of tradition over science in this context.
