寧夏枸杞? Wolfberry? Goji berry!

Wolfberry, commercially called goji berry, is the common name for the fruit of two very closely related species: Lycium barbarum (Chinese: 寧夏枸杞; pinyin: Níngxià gǒuqǐ) and L. chinense (Chinese: 枸杞; pinyin: gǒuqǐ), two species of boxthorn in the family Solanaceae (which also includes the potato, tomato, eggplant, deadly nightshade, chili pepper, and tobacco). It is native to southeastern Europe and Asia.[1]

It is also known as Chinese wolfberry, mede berry, barbary matrimony vine, bocksdorn, Duke of Argyll’s tea tree, Murali (in India),[2] red medlar, or matrimony vine.[3] Unrelated to the plant’s geographic origin, the names Tibetan goji and Himalayan goji are in common use in the health food market for products from this plant.

Safety issues

Two published case reports described elderly women who experienced increased bleeding, expressed as an elevated INR, after drinking quantities of wolfberry tea.[38][39] Further in vitro testing revealed that the tea inhibited warfarin metabolism, providing evidence for possible interaction between warfarin and undefined wolfberry phytochemicals.[38]

Atropine, a toxic alkaloid found in other members of the Solanaceae family, occurs naturally in wolfberry fruit. The atropine concentrations of berries from China and Thailand are variable, with a maximum content of 19 ppb, below the likely toxic amount.[40]

Vitamin C or L-ascorbic acid or L-ascorbate is an essential nutrient for humans and certain other animal species, in which it functions as a vitamin. In living organisms, ascorbate is an anti-oxidant, since it protects the body against oxidative stress. It is also a cofactor in at least eight enzymatic reactions, including several collagen synthesis reactions that cause the most severe symptoms of scurvy when they are dysfunctional. In animals, these reactions are especially important in wound-healing and in preventing bleeding from capillaries.
