A spiny plant with its origins in the Northern Himalayas, barberry is now extensively cultivated throughout equatorial Asia, South America, Africa, and even some regions of Europe. Approximately 9 feet tall, the barberry bush has gray, thorny limbs. April through June sees the blooming of bright yellow blossoms, which turn into the fall's dark, drooping clusters of crimson berries. For therapeutic reasons, the berries, bark, and root are all used. Barberry contains alkaloids in its stalk, root bark, and berries, with berberine being the most noticeable. Research on berberine in test tubes and on animals suggests that it has antibacterial, anti-inflammatory, hypotensive (lowering blood pressure), calming, and anticonvulsant properties. Barberry is offered as a skin salve, liquid extract, tincture, and tablet. Barberry stems that have been dried can also be brewed into tea. Barberry preparations are regulated to contain 8–12% alkaloids (berberine). Barberry trees come in a wide range of types, and their berries can be consumed. They have a tart taste and are frequently turned into preserves and jellies. Zereshk polow ba morgh, a rice meal with barberries and raisins, is a well-known delicacy in Iran.
