Objective: Qianliguang (Senecio scandens) is a common Chinese medicinal herb. Qianliguang-containing herbal proprietary products are registered as over-the-counter remedies in China and exported to Western countries. The presence of hepatotoxic pyrrolizidine alkaloids (PAs) has raised concerns about the safety of using Qianliguang and its products. https://globechemicalcompanyls.shop/product-category/towels/
