But the quality of moxa cones of various brands on the market is uneven, the beads are mixed with the eyes of the fishes, and the research on the quality and the quality control of the moxa cones is less. In the clinical treatment process, moxibustion mainly stimulates acupuncture points through various effects of acupuncture points, medicines, heat radiation, infrared radiation and the like, so that a treatment method for preventing or treating diseases is achieved. After receiving the electric wave with specific wavelength and intensity based on human body matching, the electric wave generates resonance with the same substances contained in the cells in the human body, thereby enhancing the microcirculation effect, promoting metabolism, generating the repair to the pathological changes of the human body, leading patients to be quickly recovered and leading non-patients to improve the self resistance.

1.1 materials and instruments
1.1.1 Experimental materials: moxa sticks of different brands, fixing frames, lighters, candles, timers and rulers
1.1.2 Instrument: terahertz spectrometer (Brookvertex 80 v)
1.2 experimental grouping: grouping moxa cones into 23 groups according to brand and different series of the same brand, and specifically grouping as shown in Table 1 below
Wherein the moxa roll for 2 times, the moxa roll for 3 times, the moxa roll for 4 times, the moxa roll for 5 times and the moxa roll for 6 times are prepared from moxa sticks (Jiangxi moxa Biotechnology Co., Ltd.) by different processing technologies, which is shown in Table 2.
Note: the fluff yield refers to the mass ratio of the raw material moxa to the processed moxa.
And (3) randomly extracting 6 moxa cones from each group of the 23 groups respectively for measuring the terahertz wave energy.
1.3 detection method
1.3.1 the moxa cone was fixed to the frame so that it was centered at the emission port, 16cm therefrom, because too close to the emission port easily damaged the emission port.

1.3.3 igniting the moxa cone, measuring 373 wave band terahertz magnetic wave intensity values by each moxa cone, measuring 50-60 times of each wave band intensity value, taking the average value, listing moxa cones with the serial number of 1 in the table 1 for 2 times of moxa sticks (2 times of moxa filtration), taking 373 wave band terahertz magnetic wave intensity values measured by parallel samples with the serial numbers of 1-3 respectively, wherein the numerical value represents the number of photons in a certain wave band and has no unit. The results are shown in Table 3 below.
1.3.4 the apparatus is deflated and calibrated for the next sample test.
1.4 data processing
Data to
And +/-S (mean +/-standard deviation) represents that the terahertz wave energy is processed by adopting sps statistics17 statistical software, and the terahertz wave energy of different wave bands generated by the combustion of the moxa cones of different brands is compared and analyzed by adopting single-factor variance. Specifically processing data: each Airy pillar measures 373 wave band terahertz magnetic wave intensity values, each wave band intensity value measures 50-60 times, and the average value is taken. The 373 wave band intensity values of each brand were compared with the corresponding wave band intensity values of the blank control group.
1.5 judging the quality of the moxa cone: the quality of the moxa cone is judged based on the combination of the high and low energy of the terahertz magnetic wave generated in the combustion process of the moxa cone by a terahertz magnetic spectrometer and the change of the waveform. The better the quality of the moxa cone, the stronger the terahertz wave intensity in each waveband is, and the emitted terahertz waves are slightly changed in waveform.
Fig. 1 is a graph showing the measurement results of the terahertz wave energy generated by the combustion of the itang 2 times through the moxa column (moxa filtration 2 times). It is found that Estang can radiate terahertz wave when burning 2 times the moxa cone, the spectrum range is 0.90-3.60THz, the photon number and intensity are both greater than 0, and the peak value is at 3.05 THz.
FIG. 2 is a graph showing the comparative analysis result of 373 wave band terahertz wave intensity values generated by eight types of moxa cones burning. The eight moxa cones specific brands (processes) shown in fig. 2 are: moxa sticks are used for 2 times (moxa filtration is performed for 2 times/ moxa hall), 3 times (moxa filtration is performed for 3 times/ moxa hall), 4 times (moxa filtration is performed for 4 times/ moxa hall), 5 times (moxa filtration is performed for 5 times/ moxa hall), 6 times (moxa filtration is performed for 6 times/ moxa hall), 5:1 (lint ratio is 5: 1), 15:1 (lint ratio is 15: 1) and 25:1 (lint ratio is 25: 1). In order to make the statistical analysis chart clearly show and facilitate the comparison of the results, the comparative analysis results of 373 wave band terahertz wave intensity values generated by the combustion of the other 15 types of moxa cones are not shown in the chart together except the eight types of moxa cones.
From the terahertz wave intensity waveform diagrams of the eight moxa sticks in fig. 2, it can be seen that: the moxa roll 5 times (moxa filtering 5 times) has the highest intensity in each 373 wave bands, and the emitted terahertz waves have slight changes in waveform, so that the quality of the eight moxa rolls is moxa roll 5 times (moxa filtering 5 times) relatively better.
