Title: Indigenous Iranian Plant, Zereshk, Gains Scientific Recognition for Liver Health Benefits
In a development highlighting the synergy between traditional Iranian medicine and modern science, the native Zereshk plant (Berberis vulgaris) is being recognized for its significant health properties, particularly for liver function.
A Heritage of Healing
Dr. Mohammad Mehdi Zar Shenas, an academic member of Shiraz University of Medical Sciences, emphasized that Zereshk, a red, sour-tasting berry native to Iran’s mountainous regions, holds a revered place in Iran’s rich history of traditional medicine. For centuries, it has been documented in authoritative Iranian medical texts as a potent liver tonic, a reducer of bile, and a blood purifier.
Scientific Validation of Traditional Wisdom
Dr. Zar Shenas explained that the ancient belief—that Zereshk alleviates feelings of heaviness, bitterness in the mouth, and skin yellowness by reducing liver heat and cleansing biliary ducts—is now finding resonance in modern pharmacological research. Recent studies have identified a key active compound in the plant called Berberine.
This compound, with its anti-inflammatory and antioxidant properties, is shown to protect liver cells. According to the expert, Berberine supports liver health by regulating bile secretion, inhibiting the production of free radicals, and reducing inflammation. Some research reports indicate that this medicinal plant has helped reduce liver enzymes in patients with fatty liver disease.
Guidelines for Proper Consumption
Stressing the importance of correct usage, the traditional pharmacy specialist recommended a mild tea or infusion of Zereshk for home consumption. He advised families to avoid industrial Zereshk juices, which may contain colors or additives. For therapeutic purposes, standardized products containing Zereshk extract or Berberine are more reliable as they have a specified dosage.
A Note of Caution
The report also included important cautions from Dr. Zar Shenas. Excessive consumption of Zereshk may cause side effects such as low blood pressure, diarrhea, stomach irritation, and weakness in some individuals. Pregnant and breastfeeding women must consult their physician and pharmacist before use. Diabetic patients should also be mindful of its blood sugar-lowering effects, which could interact with their regular medications.
Complementary, Not a Replacement
Dr. Zar Shenas was clear that Zereshk does not replace conventional medical treatments. While it can serve as a natural supplement alongside a healthy diet and proper lifestyle, it should not be substituted for the treatment of serious conditions like hepatitis or liver failure. He concluded by emphasizing the essential rule of consulting a doctor or pharmacist before using any herbal product to determine the appropriate dosage and check for potential drug interactions.
