Traditional Chinese Medicine (TCM) concentrated granules are a convenient and potent form of herbal medicine. However, like any natural product, they can degrade over time if not stored properly. Here are some key signs to look for to determine if your TCM granules have gone bad:

Expiration Date: Always check the expiration date on the packaging and use the granules before this date to ensure maximum potency and safety. While some granules may remain effective beyond their expiration date, it is generally recommended to use them within the specified period.

Clumping: Clumping is common and does not necessarily indicate degradation, but it can be a sign of moisture exposure. If the granules have clumped together, try shaking the container or using a fork to separate them. If clumping persists, the granules may have been compromised.

Color Changes: Significant color changes in the granules may indicate that they are no longer potent. Compare the color to a fresh batch or the original packaging to assess if it has changed dramatically.

Odor: An off or unusual smell can be a sign that the granules have degraded. If the granules have a strong, unpleasant odor that is different from when you first opened the container, it's best to discard them.

Taste: While TCM granules don't always taste great, a very bitter, metallic, or unpleasant taste that is significantly different from when you first started taking them could mean they have gone bad.

Mold or Fungus: If you notice any visible signs of mold, fungus, or other contaminants, discard the granules immediately as they may be unsafe to consume.

To ensure your TCM concentrated granules remain potent and effective, always store them in a cool, dry place away from direct sunlight and moisture. Use airtight containers, place desiccant packets inside, and check the lids are tightly closed after each use. If in doubt, consult with your TCM practitioner or pharmacist before consuming the granules.

By being aware of these signs of degradation and following proper storage guidelines, you can maximize the shelf life and effectiveness of your TCM concentrated granules. Remember, quality TCM granules should be used within their expiration date for optimal results.
