Notopterygium incisum (Qiang huo)

Notopterygium incisum, commonly known as Qiang Huo, is a perennial herb native to high-altitude regions of China and the Himalayas. The dried root and rhizome of the plant are used in traditional Chinese medicine and are typically processed by slicing and drying before being incorporated into herbal formulations.

Qiang Huo contains various bioactive compounds, including coumarins (such as notopterol and isoimperatorin), volatile oils, and polyacetylenes. These compounds have been studied in other species for their potential anti-inflammatory, analgesic, and antimicrobial properties. Its inclusion in equine products is based on traditional use and not on equine-specific data.
