How is stability testing performed on herbal formulations?
Stability testing is necessary to ensure the product is of acceptable quality throughout its entire storage period. In order to do this, it is necessary to monitor compliance of the product with a suitable quality specification throughout the shelf life. It is not acceptable to only test at the time of expiry, for example, on a retention sample (even though the results of this type of testing may provide useful information about the overall stability of the product).
