Introduction
Moxa floss is a main combustion material of the moxibustion devices. The manufacturing process of moxa floss
involves the repeated pounding of dried mugwort in a mortar and sifting grinded mugwort in a fine sieve. The
traditional medical classics recommend selection of productBased on the products traditionally selected from
the manufacturing process has revealed that, the green part (waste particle) should be sifted out and the white
or light-yellow part should be used.
Traditionally, the quality assessment of the moxa floss has depended on the human sensory evaluation,
however, the global market requires the quantitative measurement of the quality of moxa floss for fair trade.

It is not applicable to the moxa floss which is hardened with the chemical ingredients or high pressure, or both
and carbonized moxa floss which is used for smokeless moxibustion devices.
This document specifies the quality assessment of moxa floss quality, and; categorizing or grade issue of moxa
floss is not specified in this document.

4 Sampling
4.1 General
The sampling shall be performed in a random manner. Unpredicted deformation shall not appear in the
sampling procedure.
The sampling mass shall be 3,0 g, with a tolerance of ±10 %.
More than 3 units of the specimen shall be prepared.
4.2 Sampling methods
4.2.1 Moxa floss products
Sampling of the specimen shall be performed from mass of moxa floss. Only one specimen shall be collected
from one primary package.
The mass of moxa floss shall be mixed well before sampling of the specimen because the waste particles can
be sedimented and the concentration can be different between the top and the bottom in the package.
4.2.2 Moxa floss in the moxibustion devices
A specimen from the moxa floss contained in the moxibustion device shall be collected from the final product
of the moxibustion device.
Each specimen may contain moxa floss from various units collected randomly from a different primary
package.
Sampling of the specimen shall be performed underwith an understanding of the structure of the devices. The
specimen shall not be deformed or contaminated under the sampling process.
4.3 Sample storage
The specimens shall be stored in the desiccator for more than 48 h to remove the humidity. Sulfuric acid or
other reactive materials shall not be used as desiccants. Desiccator using silica gel or electrical device may be
used. The humidity in the desiccator shall be under 11 % ± 1 % and the temperature shall be 25 °C ± 2 °C.
During the storage periods, the specimen shall not be exposed to the direct light or air flow.
