    What the source establishes

    Kew describes a shrub with slightly hairy oval leaves and small greenish-yellow flowers. Pollinated flowers develop berries that change from green to red-orange as they ripen. [1]

    The profile identifies the long roots as the part commonly dried and ground for traditional preparations. A description of root use is not evidence that leaves, berries and roots have identical composition. [1]

    How to interpret it

    Plant appearance does not establish a finished extract’s concentration, purity or clinical effect. Nor does membership in the same family as familiar vegetables establish edibility of every plant part. The botanical profile should not be used as a home identification-and-dosing protocol. [1]

    A hypothetical distinction

    Imagine two products name the same species but use different parts. Species identity alone cannot show that the preparations match a study.
