As a premier plant extract manufacturer in China, Nanjing Tong Rui Bio-Tech (TRB) supplies high-purity, certified botanical ingredients globally. Discover our core product lines below.
Horsetail Extract, derived from the ancient herbaceous plant Equisetum arvense, stands as one of the most commercially significant botanical sources of organic silica (silicon dioxide). Historically celebrated in traditional European herbalism, modern pharmacological validation has propelled Horsetail Extract to the forefront of the global nutraceutical, cosmeceutical, and agrochemical industries. The key driver behind this sustained global demand is the extract's high concentration of natural, water-soluble organic silica, which exhibits significantly higher bioavailability compared to synthetic mineral counterparts.
In the global personal care and cosmetic sectors, organic silica acts as a structural stabilizer, accelerating collagen cross-linking and enhancing the biosynthesis of glycosaminoglycans. It is widely recognized as a cornerstone ingredient in premium formulations targeting hair growth, nail plate strengthening, and skin elasticity. In the nutraceutical market, Horsetail Extract is an essential ingredient in bone density formulas, joint health remedies, and natural detox supplements due to its mild diuretic properties and role in connective tissue maintenance. Furthermore, organic agriculture is leveraging Horsetail Extract as a bio-fungicide and plant bio-stimulant, owing to its natural resistance-inducing properties against fungal pathogens.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) is China's leading manufacturer and exporter of high-quality herbal extracts and their derivatives, with a strong legacy spanning over 20 years. Founded on the principles of rigorous scientific research, industrial scaling, and customer-focused global compliance, TRB has established itself as an industry leader. We integrate advanced R&D, state-of-the-art manufacturing, and international sales to deliver premium ingredients to clients worldwide.
Our diverse portfolio includes Herbal Extracts, Natural Sweeteners, Nootropics, Vegetable & Fruit Juice Powders, Essential Oils, and Bee Products. Over the years, TRB's rapid development and dedicated service have earned us global recognition. We are proud to have been awarded the prestigious 2026 Global Biotechnology and Life Sciences Award — "Best Global Herbal Extract Provider 2026".
TRB currently operates three dedicated factories: a herbal extract facility, a specialized bee product factory, and a dedicated animal extract production facility. To guarantee absolute compliance with global regulatory standards, our production operations hold a comprehensive suite of international certifications, including GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER Certificates.
In recent years, TRB has focused on the research and development of Nootropics products, such as Brain Health Herb Extract, Anti-Aging Herb Extract, and Longevity Herb Extract, which have received highly positive feedback from our global clientele.
At TRB, we utilize a proprietary multi-stage extraction and purification system designed specifically to capture water-soluble silicic acid while removing undesirable compounds (such as thiaminase, an enzyme found in wild horsetail that degrades thiamine/vitamin B1, and traces of palustrine alkaloids). This ensures our Horsetail Extract is safe and optimized for human nutrition.
We source premium, wild-crafted, or organic-certified Equisetum arvense raw materials. Every batch is visually and chromatographically verified to exclude look-alike species like toxic marsh horsetail (Equisetum palustre).
We use a specialized hydro-ethanolic extraction process with precise temperature controls. This maximizes the extraction of natural flavonoids and water-soluble silica while deactivating thiaminase enzymes.
Advanced membrane technology separates molecular-weight compounds, concentrating key active elements like organic silica and protective polyphenols, while removing heavy metals and agrochemical residues.
Continuous low-temperature spray drying yields a fine, free-flowing, and highly soluble powder. This process maintains physical consistency, bulk density, and dissolution rates across production runs.
Standardizing natural silica poses analytical challenges. Standard UV-Vis spectrophotometry can sometimes fail to distinguish between bioavailable silicic monomer structures and inactive polymerized silicates. TRB utilizes dual verification methods: Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for total elemental silicon validation and gravimetric analysis for overall silica content.
Our quality control labs test every batch for heavy metals (Lead < 3.0 ppm, Arsenic < 2.0 ppm, Cadmium < 1.0 ppm, Mercury < 0.1 ppm), pesticide residues (USP <561> compliance), and microbiological purity. This guarantees that our Horsetail Extract meets and exceeds the stringent standards of the US Pharmacopeia (USP) and European Pharmacopoeia (EP).
Nanjing Tong Rui Bio-Tech leverages China’s mature industrial clusters to build a highly resilient botanical supply chain. Located in Nanjing’s Pioneer Bio-Park, our facilities utilize advanced logistics networks, reliable energy supplies, and direct pipelines to major shipping ports (such as Shanghai and Ningbo). This ensures prompt dispatch and reliable global delivery times.
Unlike small-scale facilities, TRB maintains a large inventory of raw herbs and standardized powders. This buffered supply chain strategy protects our clients from seasonal shortages, harvest variations, and international market price volatility.
Our facilities also feature automated manufacturing controls that reduce human error, optimize solvent recovery, and lower production costs. We pass these savings directly to our customers through competitive wholesale pricing, without compromising quality.
We work closely with client product developers to match Horsetail Extract specifications with their targeted application requirements and regional regulatory frameworks:
We provide full structural documentation, allergen statements, and non-GMO self-declarations to support dietary supplement manufacturers under FDA 21 CFR Part 111 regulations.
Our ingredients align with EU food safety standards and CosIng database listings for cosmetics, backed by comprehensive Technical Data Sheets (TDS) and safety documentation.
We supply bulk, water-soluble grades designed for organic farming, serving as natural biostimulants that improve cellular resilience in crops.
Explore our broad range of high-performance natural extracts, manufactured under strict quality standards to serve global health and wellness industries.
