The production process of Horsetail Extract Powder primarily involves the following steps:
1. Raw Material Preparation
Selection of high-quality horsetail grass as raw material, typically using its dried aerial parts.
Chopping or grinding the horsetail grass into fragments, passing it through a 10-40 mesh sieve.

2. Extraction Process
Solvent Selection: Common extraction solvents include aqueous ethanol solutions (40%-80%), petroleum ether, chloroform, or methanol.
Extraction Method: Mixing the ground horsetail grass with the solvent, followed by heating, reflux, or room temperature maceration. For example, using a 40%-80% aqueous ethanol solution, an extraction temperature of 70-90℃, and an extraction time of 2 hours, is typically performed twice.

3. Concentration
Vacuum concentration of the extract to recover the solvent. The concentration temperature is usually below 65℃, and the vacuum degree is -0.05MPa to -0.088MPa.
The specific gravity of the resulting concentrate is approximately 1.05-1.1.

4. Purification and Precipitation
Adding a Ca(OH)₂ aqueous solution, equivalent to 0.1 times the volume of the concentrate, into the concentrate, stirring evenly, and allowing it to settle for 12-36 hours. Then, filtering the supernatant.

5. Drying and Grinding
Adding maltodextrin (approximately 10% of the final product weight) to the filtered liquid, mixing evenly, and then spray drying.
The inlet air temperature for spray drying is 160-200℃, and the outlet air temperature is 90-100℃.
Grinding the dried product and passing it through an 80-200 mesh sieve.

Q1: Why is ICP spectrometry used to measure silicon content rather than HPLC? Silicon is an inorganic element, not an organic molecule - it cannot be quantified by HPLC, which separates and detects organic compounds. ICP (Inductively Coupled Plasma) spectrometry is the appropriate analytical method for elemental silicon quantification, providing accurate, matrix-independent measurement of total silicon content. Some suppliers use colorimetric methods (molybdate-based assays) as a lower-cost alternative, but these are less specific and can be confounded by other silicate species in the matrix. Our silicon data is generated exclusively by ICP, ensuring results that align with what accredited third-party labs will independently obtain.

Q2: What is thiaminase, and why does it matter for horsetail extract safety? Thiaminase is an enzyme naturally present in raw E. arvense herb that catalyzes the cleavage of thiamine (vitamin B1). Prolonged consumption of raw horsetail herb or unprocessed herb powder could theoretically contribute to thiamine depletion, particularly in individuals with marginal thiamine status. In properly processed extract where thiaminase has been heat-inactivated, this concern is eliminated. The EMA monograph for Equisetum arvense specifically notes that thiaminase activity should be absent in finished preparations. We confirm thiaminase inactivation by enzymatic assay on every batch - this is not a routine step at most suppliers, but it is standard practice at Jiuyuan.

Q3: How does the silicon in horsetail extract compare in bioavailability to silicon dioxide used as a food additive? Silicon dioxide (E551) used as an anti-caking agent in food is amorphous or fumed silica - an inorganic form with very low gastrointestinal bioavailability. The silicon in horsetail extract exists predominantly as orthosilicic acid (OSA) and silica-polysaccharide complexes, which are considerably more bioavailable. Published research has characterized OSA as the primary absorbable silicon species in biological systems. This bioavailability distinction is the core pharmacological rationale for using botanical silicon sources like horsetail extract rather than inorganic silicon compounds in nutritional supplements.

Q4: Can you confirm that your horsetail is Equisetum arvense and not Equisetum palustre?** Yes. Species authentication is a mandatory incoming QC step, not an optional service. E. palustre (marsh horsetail) can occur as a contaminant in wild-harvested E. arvense collections and carries palustrine alkaloids that are absent in E. arvense. Our botanical authentication protocol uses macroscopic stem morphology examination and microscopic cross-section analysis to confirm species identity on every incoming lot. Authentication records are retained and available for regulatory audit.

Q5: Is horsetail extract regulated as a novel food in the EU? Equisetum arvense herb preparations have a documented history of traditional use in Europe predating May 1997 and are not classified as novel food under EU Regulation 2015/2283. The plant is covered by an EMA Community Herbal Monograph (published 2016) supporting traditional use for minor urinary complaints and as a supportive treatment for minor wounds. Buyers developing EU food supplements or THMPs should review the EMA monograph and consult their regulatory counsel for application-specific guidance.

Q6: What is the recommended dosage of horsetail extract for hair, skin, and nail support formulations? The EMA Community Herbal Monograph for Equisetum arvense herb specifies a traditional use dose corresponding to 2–4 g of dried herb per day for adult use. For a standardized extract at 7% SiO₂, this corresponds approximately to 300–600 mg extract per day, delivering roughly 21–42 mg SiO₂. Most commercial hair, skin, and nail supplement formulations in the US and EU market use 300–500 mg of standardized horsetail extract per serving. Formulators should reference the EMA monograph and applicable national regulations for specific dosing language on product labels.

Q7: Can your horsetail extract be used in cosmetic formulations as well as ingestible supplements? Yes. Horsetail extract is used in both ingestible and topical applications. For topical use in hair serums, nail treatments, and skin-firming formulations, the silicon-rich and flavonoid-rich extract fraction is applied for its reported strengthening and antioxidant properties. For cosmetic applications, we provide a dedicated cosmetic-grade COA with heavy metal testing aligned to EU Cosmetics Regulation (EC) No 1223/2009 limits. Confirm your intended application when requesting documentation.

Q8: Does the high ash content of horsetail extract indicate poor quality? No - and this is a common misunderstanding that creates unnecessary friction in the qualification process. The elevated ash content (≤ 20%) in horsetail extract is a direct consequence of the plant's exceptional capacity to accumulate silicon, potassium, calcium, and other minerals from soil. It is an intrinsic botanical characteristic, not a processing artifact or quality defect. The European Pharmacopoeia monograph for Equisetum arvense herb explicitly accounts for this elevated mineral content in its quality specifications. Buyers whose QC teams flag high ash content should be directed to the EP monograph for context.
