Explore our highly standardized raw materials and botanical extracts designed for global commercial and pharmaceutical formulation.
In the modern phytopharmaceutical and botanical ingredients landscape, Eyebright Extract, derived from the semi-parasitic plant Euphrasia officinalis (also referred to as Euphrasia stricta), has solidified its position as a high-demand active ingredient. Historically revered in European folk medicine for treating ocular inflammatory conditions, modern clinical biochemistry is now verifying its complex phytochemical makeup. Today, the global demand for Eyebright Extract is surging, driven by two key secular trends: the ubiquity of digital eye strain (Computer Vision Syndrome) in an increasingly digital world, and the cosmetic industry's shift toward functional, clean-label raw materials for anti-aging and anti-puffiness eye care treatments.
As a leading Chinese botanical extraction pioneer, we supply stabilized, bioavailable, and contaminant-free Eyebright Extract to global brand owners, pharmaceutical compounders, and supplement manufacturers. Our industrial scaling ensures batch-to-batch consistency of key bioactives, including Iridoid Glycosides (Aucubin), Flavonoids (specifically Luteolin and Quercetin derivatives), Tannins, and Phenolcarboxylic acids.
The primary therapeutic marker of Eyebright is Aucubin, an iridoid glycoside boasting powerful anti-inflammatory and cellular protective benefits. Our customized extraction procedures are optimized to maximize the retention of these thermolabile glycosides and synergistic tannins, providing high-efficacy raw materials for both liquid drops and solid dosage formulations.
We provide water-soluble powder forms, hydro-glycolic liquid extracts for cosmetic formulations, and standardized ratio extracts (4:1, 10:1, and up to 20:1) tailored to meet the strict regulatory guidelines of the US FDA, European EFSA, and China's NMPA.
Leveraging high-performance liquid chromatography (HPLC) and thin-layer chromatography (TLC), we guarantee strict control over heavy metals, pesticide residues, and microbial counts. Every batch is supplied with an exhaustive Certificate of Analysis (COA) to streamline global customs clearance.
How Eyebright Extract is transforming modern wellness, clean cosmetics, and ophthalmology formulations across regional markets.
The commercial application of Euphrasia officinalis has expanded significantly beyond traditional herbal teas. Today, it represents a core constituent in premium eye health matrices alongside Lutein, Zeaxanthin, and Bilberry extract. Geographically, North America and Europe lead the consumption of dietary supplements containing Eyebright, targeting digital fatigue and age-related vision deterioration. Concurrently, the Asia-Pacific region is experiencing rapid growth in Eyebright-infused skincare, driven by clean-label formulations designed to soothe the delicate eye area and combat oxidative damage caused by pollution and blue light exposure.

Eyebright's astringent properties make it ideal for sterile ophthalmic solutions targeting dry eyes, allergic conjunctivitis, and environmental irritation. Our extractions are processed under strict microbiologically controlled conditions suitable for sterile liquid formulations.
Incorporated into capsules, tablets, and functional gummies, Eyebright works synergistically with carotenoids to support macular health, enhance microcirculation to the retina, and alleviate ocular fatigue associated with extended screen usage.
High in tannins and protective flavonoids, Eyebright is widely formulated into under-eye creams, serums, and patches to constrict minute blood vessels, reduce puffiness, brighten dark circles, and defend skin cells from oxidative stress.

A look into our scientific manufacturing process, highlighting steps to protect active compounds and ensure purity.
We source authentic wild or sustainably cultivated Euphrasia officinalis. Every batch undergoes strict macroscopic and microscopic botanical authentication, supplemented by DNA barcoding when required, to prevent any contamination or species substitution.
Because crucial active compounds like Aucubin are sensitive to heat, we employ vacuum-assisted low-temperature extraction technology. This process preserves the integrity of delicate iridoid glycosides and prevents the degradation of key flavonoids.
The extract undergoes state-of-the-art filtration and membrane separation to isolate active fractions while removing inert plant sugars. The solution is concentrated under vacuum pressure to maintain maximum bioactivity.
Utilizing rapid spray-drying in clean-room environments (Class 100,000), we transform the concentrate into a free-flowing, highly soluble powder. Standardized particle sizing (typically 80-100 mesh) ensures uniform blending in final formulations.
Our Quality Assurance system ensures that every shipment complies with the following rigorous parameters:
| Parameter | Specification Limit | Testing Method |
|---|---|---|
| Active Marker (Aucubin) | Standardized from 1.0% to 5.0% | HPLC (High-Performance Liquid Chromatography) |
| Extract Ratio | 4:1, 10:1, 20:1 | TLC (Thin Layer Chromatography) |
| Heavy Metals (Pb, As, Cd, Hg) | < 10 ppm total (Individual limits < 1 ppm) | ICP-MS (Inductively Coupled Plasma Mass Spectrometry) |
| Pesticide Residues | Compliant with USP & EC 396/2005 regulations | GC-MS / LC-MS |
| Total Aerobic Count | < 1,000 cfu/g (Strictly pathogen free) | AOAC Microbiological Plate Method |
