Eyebright Extract Powder

Eyebright Extract Powder is a concentrated botanical ingredient produced from the aerial parts of Euphrasia officinalis L., a species in the Orobanchaceae family commonly known as eyebright. The aerial herb is extracted and converted into a fine dry powder, distinguishing the ingredient from directly milled eyebright herb.

Essencefield supplies ratio-based extracts including 4:1, 5:1, and 10:1 grades. The 10:1 extract serves as the principal concentrated commercial grade, while lower-ratio options provide additional flexibility for formulation and sourcing. Botanical identity, extract concentration, powder characteristics, and fingerprint identification are central parameters when evaluating this ingredient.

Ingredient Profile & Common Uses

Eyebright extract is produced from the aerial herb of Euphrasia officinalis rather than from an isolated phytochemical or simple botanical powder. The source material contains a characteristic combination of polyphenolic and iridoid constituents. Extraction concentrates selected soluble botanical components while reducing the amount of raw plant material required in the finished formulation.

Essencefield supplies 4:1, 5:1, and 10:1 ratio extracts, providing different concentration levels for formulation and procurement requirements. These grades are defined primarily by botanical source and herb-to-extract concentration rather than by a universally adopted single active-compound assay. TLC fingerprint identification supports botanical extract authentication within this ratio-based grade system.

The powder is primarily used in dietary supplements and multi-botanical formulations, including products positioned around eye and visual-wellness concepts. Its native botanical color and characteristic herbal sensory profile should be considered during formulation. In aqueous systems, the material behaves as a dispersible multi-component plant extract rather than as a purified water-soluble compound.

Application Areas

Capsules

The concentrated extract is suitable for hard-capsule supplements where formulators want to incorporate eyebright while reducing the botanical bulk associated with directly milled herb.

Tablets

Ratio extracts can be incorporated into compressed botanical products, with powder flow, blend uniformity, compression behavior, and compatibility with other ingredients evaluated during development.

Powdered Supplements

Eyebright extract can be used in sachets, stick packs, and dry blends. Native color, taste, wetting behavior, and sedimentation should be evaluated when the finished product is dispersed in water.

Multi-Botanical Formulas

The extract can be combined with complementary botanical and nutritional ingredients where a defined Euphrasia source and extract ratio provide clearer ingredient identity than generic eyebright herb powder.

Key Constituents & Extract Profile

Eyebright contains several phytochemical groups relevant to botanical identity and extract characterization. Reported flavonoids include apigenin, luteolin, kaempferol, rhamnetin, and quercetin. Phenolic constituents include caffeic-acid derivatives, chlorogenic acids, and coumaric-acid derivatives, while tannins contribute another characteristic fraction of the herb.

Iridoids represent an additional constituent class associated with Euphrasia, with aucubin serving as an important reference compound in published botanical chemistry. These constituents help characterize the source herb but should not be interpreted as quantitative standardized assays unless a commercial grade is specifically manufactured and released to a defined marker level.

For ratio extracts, commercial identity is therefore based primarily on authenticated botanical material, extraction concentration, finished powder form, and fingerprint identification. This differs from a standardized extract, where a defined quantitative marker and analytical assay form part of the purchasing specification.

Technical & Quality Considerations

Botanical authentication is particularly important for eyebright because the common name is used for multiple species within the genus Euphrasia. A commercial specification should therefore identify the declared species and aerial plant material rather than relying on “eyebright” alone. For ratio extracts, TLC fingerprinting provides a practical identity control alongside raw-material traceability and extract-ratio documentation.

The finished material is a multi-component botanical powder rather than an isolated active compound. Its plant-derived constituents contribute to native color, taste, and dispersion behavior. An 80-mesh powder format supports conventional dry blending, while aqueous applications should be evaluated for wetting, sedimentation, color contribution, and sensory impact in the finished formulation.

During capsule and tablet scale-up, R&D teams should evaluate blend uniformity, powder flow, segregation, fill-weight consistency, and compression behavior with the complete formulation. For sachets and drink powders, premixing and controlled dispersion can improve distribution. A 10:1 extract describes the concentration of botanical raw material into extract; it does not indicate that an individual flavonoid or iridoid is present at 10%.
