The quality of the moxa stick can be judged by observing its shape and color, as well as its scent and burning sensation. After use, it can achieve the effect of unblocking meridians and also has the effect of promoting blood circulation and removing blood stasis. If there is menstrual irregularity, appropriate moxibustion can also help improve the condition.

1. Observe the shape: Good moxa sticks are usually firm and not easily scattered. The moxa wool is fine, without branches or other impurities, and a certain shape can be formed by taking out an appropriate amount of moxa.

2. Observe the color: The normal color of the moxa stick is usually golden yellow, with some being earth yellow, and they look particularly fine.

3. Smell the scent: The scent of the moxa stick is usually a grassy smell, and it is quite fragrant, without a pungent smell, and relatively natural in taste.

4. Burning sensation: The burning sensation is usually not felt after lighting the moxa stick, as the inside is red and the flame is soft. After moxibustion, a comfortable feeling can be felt, and there will be no burning sensation.

Moxibustion is a method of health preservation. After lighting the moxa, it can be placed about three centimeters above the acupoint, which can disperse the internal wind-cold, achieve the effect of unblocking meridians, and also help promote blood circulation within the body. It can also regulate menstrual disorders.
