Can you drink water infused with Huang Qi (Astragalus) that has been left overnight?

It is generally not recommended to drink water infused with Huang Qi (Astragalus) that has been left overnight. If there are any concerns, it is advisable to consult a healthcare professional in advance. The detailed explanation is as follows:

When Huang Qi-infused water is left at room temperature for an extended period, it can easily become contaminated by microorganisms in the air, leading to changes in water quality. Particularly in warm and humid environments, bacteria and mold can multiply rapidly, causing the tea to spoil. Drinking such water may not only fail to provide nourishing effects but could also lead to diarrhea, abdominal pain, or other health issues.

If Huang Qi water is stored in the refrigerator at low temperatures, bacterial growth may be slowed; however, the nutritional components may degrade over time, reducing its effectiveness. Moreover, prolonged soaking may cause excessive release of active ingredients, resulting in a bitter or unpleasant taste. Even if the water appears unchanged, its safety cannot be guaranteed.

To avoid unnecessary harm to the body, it is recommended to prepare only an appropriate amount of Huang Qi water each time and consume it promptly.
