Manufacturing Process of Horsetail Extract

The manufacturing process for horsetail extract typically includes the following main steps:

  1. Raw Material Preparation: Fresh horsetail (Equisetum arvense) is collected as the raw material. The collected horsetail should meet certain growth period and quality requirements, typically harvested during the plant's active growth phase.
  2. Cleaning and Processing: The collected horsetail must be cleaned and processed to remove surface impurities and contaminants. This step usually involves soaking and rinsing with clean water to ensure the horsetail is clean and hygienic.
  3. Crushing and Grinding: The cleaned horsetail undergoes crushing and grinding to transform it into a powder suitable for extraction. Mechanical grinding equipment is used to process the horsetail into appropriately sized particles.
  4. Extraction Process: The crushed horsetail powder is extracted with a suitable solvent (e.g., water, ethanol). Traditional methods such as steeping, cold infusion, and hot infusion can be used, as well as modern techniques like ultrasonic and microwave extraction.
  5. Filtration and Concentration: The extracted mixture undergoes filtration to remove residues and solid particles, resulting in a clear extraction liquid. This extract is then concentrated through evaporation to remove the solvent, yielding a concentrated horsetail extract.
  6. Refinement and Purification: The concentrated extract can undergo further refinement and purification to remove impurities and enhance the purity and quality of the product.
  7. Drying and Packaging: Finally, the refined and purified horsetail extract needs to be dried to reduce moisture content, improving stability and shelf life. The dried product can be packaged as needed to ensure its quality and safety.

Throughout the manufacturing process, strict control of operational parameters and conditions is required to ensure the quality and stability of the extract. Additionally, the production process must adhere to relevant quality management systems and standards to ensure the product meets national and industry requirements.

Overview of the Source Plant of Horsetail Extract, Distribution, and Growth Environment

Horsetail (scientific name: Equisetum arvense), also known as field horsetail, is an ancient fern-like plant belonging to the Equisetaceae family. The following introduces the source plant, distribution, and growth environment of horsetail.

Source Plant:
Horsetail is a primitive, slender plant typically found at or near the ground level in moist environments. It features hollow stems, elongated internodes, and small green leaves that do not contain chlorophyll. Its growth form resembles that of other species in the Equisetum genus, though they are not closely related.

Distribution:
Horsetail is widely distributed across the temperate and cold regions of the Northern Hemisphere, especially in various ecosystems in Europe, North America, and Asia. In Europe and North America, it typically grows in open grasslands, riverbanks, wetlands, along streams, and forest edges. In Asia, it can also be found on slopes, fields, roadsides, and desert areas.

Growth Environment:

  1. Moist Environments: Horsetail prefers moist habitats, such as wetlands, riverbanks, and lakeshores. It can adapt to varying moisture levels but generally favors relatively damp places.
  2. Moderate Light: Horsetail grows well in moderate light conditions, usually found in partially shaded environments, but can also adapt to fully sunlit areas.
  3. Nutrient-rich Soil: While horsetail has low soil requirements, it thrives in moist, well-draining soils rich in organic matter.
  4. Low-acid Soil: It prefers soils that are neutral, showing better growth effects in slightly neutral soils.

Overall, horsetail is a resilient and widely distributed plant that flourishes in diverse ecological environments. Its growth conditions and distribution range are influenced by geographic, climatic, and soil factors.

Processing and Storage of Horsetail Extract

The processing of horsetail extract generally involves the following steps: First, fresh horsetail is collected and cleaned to remove impurities; next, the horsetail is crushed or ground to enhance extraction efficiency; thereafter, suitable extraction methods (such as water or ethanol extraction) are employed to extract the target components; finally, through filtration, concentration, and drying processes, the extract is obtained.

For storage, horsetail extract should be kept in a dry, cool, and dark environment to prevent moisture and sunlight from causing quality changes. It is also best to minimize exposure to oxygen and other pollutants, potentially using sealed containers for storage to extend its shelf life. Under appropriate conditions, horsetail extract can typically remain effective for several years, but regular checks and tests are recommended before use to ensure its quality and efficacy.
