Ingredient Profile & Common Uses
The extract is produced from the underground rhizome of Phragmites australis rather than leaves, stems, or other aerial material. Phragmitis Rhizoma and Lu Gen are established names associated with the dried rhizome, while Phragmites communis occurs in older botanical and commercial references. The extracted material is commercially distinct from simply milled reed rhizome powder because it represents a concentrated botanical ingredient.
Commercial supply is organized around extract-ratio grades. The 10:1 specification serves as the principal grade for general botanical ingredient sourcing, while 4:1 and 5:1 provide lower-ratio formats and 20:1 provides a higher-ratio option. These designations describe botanical input relative to extract output and should not be interpreted as percentages of polysaccharides, flavonoids, phenolic compounds, or another single active constituent.
The powder is mainly used in dry botanical systems where its natural beige-to-light-brown color and mild earthy character can be incorporated into the finished formulation. In aqueous systems, it forms an opaque botanical dispersion rather than a clear solution, making wetting, suspension stability, re-dispersibility, and sedimentation relevant considerations during formulation development.
