Black Hollyhock
Alcea rosea
Alcea rosea, commonly known as hollyhock, is a traditional plant with origins in Asia and Europe. Traditionally, it has not been extensively used for medicinal purposes across various cultures. Scientific evidence suggests that silver nanoparticles synthesized from Alcea rosea leaf extract exhibit moderate antibacterial properties, mild antioxidant activity, and significant anticancer effects against cervical cancer cell lines. Additionally, the plant shows enhanced tolerance to heavy metal stress in roots but may increase toxicity under combined stress conditions. Alcea rosea root extracts have demonstrated some ameliorative effects on hepato-renal function markers and hematological parameters in rats exposed to ethylene glycol toxicity. Nanoemulsions containing polyphenols from various plants, including those derived from Alcea rosea, enhance intestinal release and antioxidant activity; however, anthocyanins may degrade significantly during this process. No major safety issues or recorded drug interactions have been identified with the use of Alcea rosea.

What the science says
- The study found that silver nanoparticles synthesized using Alcea rosea leaf extract showed moderate antibacterial and mild antioxidant activity, along with significant anticancer activity against cervical cancer cell lines.
- Alcea rosea showed enhanced tolerance to cadmium and lead stress by modulating antioxidant enzymes and metal accumulation in roots, but combined stress increased metal toxicity and mobility.
- Alcea rosea root extract showed some ameliorative effects on hepato-renal function markers and hematological parameters in rats exposed to ethylene glycol toxicity.
- Nanoemulsions encapsulated polyphenols from various plant sources, enhancing their intestinal release and antioxidant activity, though anthocyanins degraded significantly.
