Barberry is a big bush that can grow up to about 15 feet high. Originally from Europe, it’s now commonly found in Iran and also grown in parts of the US. Its leaves resemble those of a holly bush and it produces red berries. The bark of the trunk and root is well-known for its medicinal benefits due to the alkaloids it contains, which help with various bodily functions, especially digestion.
In traditional medicine, barberry has been a remedy for almost every type of stomach issue, as well as problems with the lymphatic and urinary systems, and respiratory infections. It has been used as a bitter tonic and as a fever reducer. The main alkaloid in barberry, berberine, is a strong antibiotic, astringent, and anti-fungal agent. It helps manage the overgrowth of candida and acts as a bactericide, which is an advantage over typical antibiotics. It also helps control infectious diarrhea and boosts the production of digestive enzymes.
Barberry is referred to as “Holy Thorn” in Italy because it was believed to be part of the crown of thorns worn by Jesus. Some sources suggest that barberry can positively affect blood pressure by dilating the blood vessels. Traditionally, it has been used to treat hepatitis, colic, jaundice, diabetes, and even consumption.
Externally, barberry root has applications for treating sores, burns, ulcers, acne, itchiness, ringworm, cuts, and bruises. Under medical supervision, it may be recommended for treating congestive jaundice and inflamed gallbladders, as well as gallstones. As a bitter tonic with mild laxative properties, it has been used by individuals who are weak or debilitated to strengthen and cleanse their system. It is also believed to help with an enlarged spleen, combat malaria, and be effective against protozoan infections.
Berberine, found in barberry, exhibits strong antibacterial properties and is useful as an external compress for inflammatory eye conditions like blepharitis and conjunctivitis.
The stem, root bark, and fruit of barberry contain alkaloids, especially berberine, that have been shown in lab studies to possess antimicrobial, anti-inflammatory, blood pressure-lowering, sedative, and anticonvulsant effects. Berberine can also stimulate the immune system and act on the smooth muscles in the intestines, which might improve digestion and alleviate gastrointestinal pain.
The barberry plant’s berries are also nutritious, used in some recipes around the world, and are high in citric acid and vitamin C. They are also a good source of berberine. Typically, remedies use the root bark while berries are used in cooking, although both parts have medicinal properties. Barberry is available in capsules, dried form, tinctures, and dried berries.
