Explore our elite range of verified high-purity botanical raw materials and custom production lines.
In the rapidly changing landscape of preventative wellness and functional healthcare, botanical formulas must demonstrate rigorous scientific efficacy and tangible bio-behavioral advantages. The pairing of Stinging Nettle (Urtica dioica) and Quercetin represents one of the most clinically sound and commercially viable synergies in modern nutraceutical design. For global procurement officers, understanding the underlying pharmacodynamics of this combination is crucial to capturing premium market segments.
Urtica dioica, commonly known as stinging nettle, possesses a rich array of bioactive constituents including lignans, flavonoids, phenolic acids, and phytosterols. Historically valued for its restorative qualities, contemporary molecular biology reveals that nettle extract acts at the genetic level, down-regulating inflammatory pathways by inhibiting the nuclear transcription factor kappa B (NF-κB). Furthermore, it works as a mild, natural diuretic and joint supporter, binding to sex hormone-binding globulin (SHBG) to promote hormonal homeostasis.
"Clinical trials demonstrate that the combined action of Nettle and Quercetin reduces seasonal discomfort scores by up to 58% compared to placebo. By targeting distinct biological receptors, this duo achieves a multiplier effect in the human immune response system."
Quercetin, a potent plant-derived polyphenol and flavonol (typically sourced from Sophora japonica), is renowned for its dual role as a free radical scavenger and a natural mast cell stabilizer. It limits the release of intracellular histamine, leukotrienes, and prostaglandins—the primary agents behind allergic and inflammatory cascades. However, Quercetin's primary challenge is its naturally low bioavailability.
This is where our proprietary OEM Nettle Quercetin formulation creates commercial value. Stinging Nettle contains naturally occurring minerals and hydrophilic molecules that act as organic carriers, increasing the dispersion rate of Quercetin in the digestive tract. Together, they form a multi-pathway defense mechanism: Quercetin suppresses mast cell degranulation, while Nettle blocks the H1 receptor pathway and prevents the synthesis of inflammatory prostaglandins via cyclooxygenase (COX-1 and COX-2) inhibition.
A premier high-tech enterprise specializing in R&D, production, and sales of botanical extracts.
Chengdu Chenlv Herb Co., Ltd. (referred to as "Chenlv Herb") is established as a leading botanical extraction facility in Sichuan Province, China—a region globally recognized for its abundant medicinal herb reserves. We specialize in providing high-purity, highly active, and premium-quality natural raw materials serving diverse global sectors, including pharmaceuticals, health supplements, functional foods, and high-end cosmetics.
Our core mission revolves around delivering structural reliability and chemical uniformity in every batch. Utilizing advanced chromatographic separation, low-temperature vacuum concentration, and automated spray drying, we maintain the organic structure of the active compounds.
The global demand for botanical extracts has transitioned from basic herbal powders to highly standardized active pharmaceutical ingredients (APIs). In the post-pandemic market, consumer preferences have shifted decidedly toward clean-label, plant-based remedies with verified mechanisms of action. Procurement directors in North America, Europe, and the Asia-Pacific region are increasingly seeking reliable partners capable of providing customized compound formulas, such as Nettle Quercetin, to reduce formulation complexity and expedite time-to-market.
To address these requirements, Chenlv Herb provides an optimized supply chain that integrates raw material cultivation, advanced extraction, and customized packaging. Our vertical integration shields buyers from the price volatility of agricultural commodities and ensures that every shipment aligns with GMP standards.
We deliver premium-grade active components, custom formulations, and unmatched global compliance.
Continuous molecular isolation studies ensure custom ratios and optimized solubility for all beverage, capsule, and tablet configurations.
Low-temperature vacuum concentration and rapid atomizing spray driers preserve active constituents while slashing production timelines.
Sustainably wildcrafted Urtica dioica and ethically harvested Sophora japonica form the foundation of our transparent supply chains.
We provide professional consultation, customs assistance, safety testing, and flexible logistical support from factory door to your warehouse.
Analytical confirmation via HPLC, UV-Vis, GC-MS, and ICP-MS verifies that every batch meets global purity standards.
Over a decade of direct B2B exportation to major consumer markets, handling custom regulations, logistics, and compliance.
Our R&D division at Chenlv Herb is dedicated to overcoming the inherent biological limitations of botanical flavonoids. Natural Quercetin possesses a highly crystalline, hydrophobic structure that results in less than 10% systemic absorption in human trials. Similarly, the key active components of Stinging Nettle (such as caffeic malic acid and polysaccharides) are susceptible to thermal degradation if processed using conventional extraction techniques.
To address these limitations, our manufacturing facilities employ a proprietary multi-phase technical roadmap:
By combining micronized Quercetin with standardized Nettle leaf extract (typically standardized to 1% silica or 2% silica), our final formulation provides a stable, free-flowing powder that is ideal for automatic encapsulation, hard shell capsules, tablets, and drink mixes.
Our comprehensive, one-stop contract manufacturing workflow ensures precision and predictability.
Define product specifications, potency targets, and volume expectations.
Receive a clear breakdown of raw material, extraction, and logistics costs.
Establish quality parameters, batch agreements, and delivery timelines.
R&D creates lab-scale pilot samples for physical and chemical approval.
Full-scale processing in our GMP-compliant, high-volume production lines.
Rigorous internal and third-party laboratory testing before release.
Direct export from our factory to your global distribution centers.
Our standardized botanical formulations support applications across multiple functional industries.
Widely integrated into allergy support capsules, immune defense formulas, respiratory ease tablets, and daily vitality supplements.
Acts as a clean, natural therapeutic agent in botanical drugs and clinical-grade formulations targeting chronic systemic inflammation.
Incorporated into topical gels, anti-redness creams, and protective skincare serums to calm inflamed skin and scavenge free radicals.
Used as a natural feed additive to replace synthetic antibiotics, improve immune response in high-value livestock, and promote general health.




Sourcing botanical extracts from an international partner requires strict attention to regulatory detail. At Chenlv Herb, we believe compliance is not an afterthought; it is a core business value. We ensure that our extraction methodologies, raw materials, and processing environments comply with the standards of major import markets.
Our facility maintains certifications from recognized global organizations, including ISO 9001 for manufacturing consistency, ISO 22000 for food safety management, and Kosher and Halal to accommodate diverse consumer demographics. For US-based manufacturers, our facilities are FDA-registered and ready for foreign supplier verification audits.
Because Nettle plants naturally accumulate soil minerals, strict oversight of wildcrafting environments is essential. We test every batch of Nettle raw materials for heavy metal levels (Lead, Cadmium, Arsenic, and Mercury) using Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
Furthermore, we run comprehensive gas chromatography-mass spectrometry (GC-MS) sweeps to verify the absence of pesticide residues, complying with both EPA standards and EU regulation limits. Our extraction runs are limited to water and food-grade ethanol, eliminating concerns regarding chlorinated or toxic organic solvents.
Our systems and facilities are fully audited by top-tier global verification bodies.
