Introduction
Interpretation of the core content of the standard
This standard establishes complete technical specifications for the key links of moxa for moxibustion, such as raw materials, processing technology, quality grading, etc., for the first time, mainly including:
- Raw material requirements: Limited to the use of dried leaves of Artemisia argyi of the Asteraceae family, which must be stored for ≥1 year
- Processing ratio: The ratio of raw materials to finished products is not less than 3:1 (3kg of wormwood leaves are used to make 1kg of moxa)
- Quality grading: According to indicators such as powder content and fluffiness, it is divided into Grade I (for direct moxibustion) and Grade II (for moxibustion with moxa sticks)
Comparison of key technical indicators
| Test items | Grade I standard | Grade II standard | Test method |
|---|---|---|---|
| Dust content | ≤7.0% | 7.0-15.0% | 16 mesh sieve vibration method |
| Bulkyness | ≥50mm | 25-50mm | 50g/500g pressure difference method |
| Microscopic grinding degree | ≥85% | 60-85% | Stereo microscope method |
Analysis of implementation points
Quality Control of Mugwort Smoke
The standard innovatively introduces the indicators of Similarity of Mugwort Smoke Fingerprint (≥80%) and Tar Content (≤45mg/g), through:
- Gas chromatography to establish standard fingerprint
- Special collector to determine total particulate matter
- Isopropyl alcohol extraction-water subtraction method to calculate tar amount
Production Process Recommendations
In order to meet the requirements of Class I standards, it is recommended to:
- Use three-year-old mugwort leaves as raw materials
- Multiple air separations to remove stem impurities
- Low-temperature and low-speed crushing process to control dust content
Technical Evolution of Standards
Compared with traditional experience judgment, this standard has achieved three major breakthroughs:
- The first establishment of Standard atlas of microscopic identification of moxa (T-shaped hair characteristics)
- Introducing the quantitative index of fluffiness to reflect the processing fineness
- Standardizing the storage conditions of moxa (20cm above the ground, relative humidity ≤65%)
