Lycium barbarum Fruit Identity & Plant Part
The botanical entity is Lycium barbarum L., a deciduous shrub of the nightshade family (Solanaceae) grown across northwestern China. The part used is the ripe fruit, an oval red berry that is dried before processing. Leaves, root bark and seeds are not added separately to this goji berry extract. The root bark of Lycium shrubs is a separate traditional material, unrelated to the fruit in use.
Two mix-ups are common. The berries of Lycium chinense, a close relative, also trade as goji or wolfberry, and the two fruits differ in metabolite profile. Separately, the leaf of the same shrub is sold as wolfberry leaf, an ingredient with its own extracts.
