Standard Herb Extract

A standard herb extract, also known as a standardized herbal extract, is a type of botanical extract that is processed to contain a specific, consistent amount of one or more active compounds. The goal of standardization is to ensure that each batch of the extract has the same potency and therapeutic effects. This is particularly important in herbal medicine and dietary supplements, where consistency and efficacy are crucial.
