Bearberries
Arctostaphylos
Arctostaphylos, commonly known as uva-ursi, is a plant that traditionally has not been extensively used in medicine. However, scientific research has shown promising results. The ethyl acetate sub-extract from the fruits of Vaccinium arctostaphylos demonstrated strong tyrosinase and melanin inhibition, comparable to standard compounds. Additionally, uva-ursi silver nanoparticles exhibited potential antiviral activity against HSV-1 by interacting with the viral envelope. Hot water extraction was found to be more effective for extracting polyphenols from most plant species; however, Arctostaphylos uva-ursi and Rhododendron tomentosum were exceptions, where maceration proved more effective. Uva-ursi has been traditionally favored for treating uncomplicated urinary tract infections based on patient-reported outcomes. No major safety issues or drug interactions have been recorded, but further research is needed to confirm these findings comprehensively.
