Black Hollyhock

Alcea rosea, commonly known as hollyhock, is a traditional plant with origins in Asia and Europe. Traditionally, its use has not been extensively documented, though it has been employed for various purposes such as dyeing fabrics due to the vibrant colors of its petals. Scientific evidence suggests that Alcea rosea may have potential benefits; studies indicate enhanced tolerance to heavy metal stress by modulating antioxidant enzymes and metal accumulation in roots, although combined stress can increase toxicity. In another study, root extracts showed some ameliorative effects on hepato-renal function markers and hematological parameters in rats exposed to ethylene glycol toxicity. Additionally, the plant has shown moderate antibacterial activity and significant anticancer potential when used for synthesizing silver nanoparticles. Nanoemulsions encapsulating polyphenols from Alcea rosea have enhanced intestinal release and antioxidant activity, though there is a notable degradation of anthocyanins during this process. No major safety issues or drug interactions have been recorded to date.
