As a commonly used traditional Chinese medicine, the shelf life of moxa sticks is affected by various factors, including storage conditions, production processes, etc. Here are some detailed information about the shelf life of Ai Tiao:
Shelf life of mugwort in the market
The shelf life of mugwort sold in the market is usually marked as 3-5 years. This is because under appropriate storage conditions, moxa sticks can maintain their efficacy for a longer period of time. If the mugwort is stored properly and there is no mold or decay, it can still be used even if it exceeds the labeled shelf life.
The actual shelf life of Ai Tiao
In fact, Ai Tiao does not have a fixed shelf life. The efficacy of moxa sticks is related to their storage time. Generally speaking, the longer the moxa sticks are stored, the better their efficacy. Some mugwort sticks can still be used even after being stored for seven or eight years. This is because during the aging process, the active ingredients of Artemisia argyi will change, making the medicinal effect of Artemisia argyi more gentle and long-lasting.
Precautions for storing mugwort sticks
In order to ensure the quality of mugwort and extend its shelf life, the following points need to be noted:
Store in a well ventilated and dry place, avoiding moisture and direct sunlight.
Wrap in plastic bags or sealed boxes to prevent moisture regain.
Avoid contact with air to reduce the possibility of oxidation and moisture.
Freezing and storing in the refrigerator can effectively prevent the deterioration and insect infestation of mugwort sticks.
In summary, the shelf life of mugwort is not fixed, but depends on its storage conditions and duration. As long as stored properly, the shelf life of mugwort can far exceed the indicated period.
