Liver diseases characterized by inflammation or tissue damage affect the optimal functioning and increase the morbidity and mortality of the affected individual. Liver diseases are a largely neglected health issue and recent reports indicate that they affect over 10% of the world population, with the highest burden in low and middle income countries that have minimal medical resources. To complicate matters the currently available pharmacological therapies are not optimal and when used for extended periods of time impart systemic toxicity. Diet can modify pathophysiological processes, including those of hepatotoxins, and studies have shown that some dietary constituents can afford heptoprotection. Emblica officinalis Gaertn or Phyllanthus emblica Linn, commonly known as the Indian gooseberry in English or amla in Hindi, is one of the most important medicinal and dietary plants in the Indian subcontinent. The fruits are of dietary and medicinal use and have wide applications in both traditional and folk systems of medicine. Scientific studies have shown amla to be effective in preventing/ameliorating the toxic effects of hepatotoxic agents like ethanol, paracetamol, carbon tetrachloride, heavy metals, ochratoxins, hexachlorocyclohexane, antitubercular drugs and hepatotoxicity resulting from iron overload. Amla is also reported to impart beneficial effects on liver function and to mitigate hyperlipidemia and metabolic syndrome. Amla possesses protective effects against chemical-induced hepatocarcinogenesis in animal models of study. Additionally, the phytochemicals quercetin, gallic acid, corilagin and ellagic acid are also reported to protect against the cytotoxic effects of paracetamol, microcystins, galactosamine and lipopolysaccharide. The hepatoprotective actions of amla appear to be mediated by its free radical scavenging, antioxidant, anti-inflammatory and modulation of the xenobiotic detoxification process and lipid metabolism.
肝脏疾病以炎症或组织损伤为特征,影响其最佳功能,并增加受影响个体的发病率和死亡率。肝脏疾病是一个被严重忽视的健康问题,最近的报告表明,全世界有超过 10%的人受到影响,其中负担最重的是医疗资源最少的低收入和中等收入国家。更复杂的是,目前可用的药物治疗方法并不理想,而且长期使用会产生全身毒性。饮食可以改变病理生理过程,包括肝毒素的过程,研究表明,一些饮食成分可以提供肝保护。余甘子或诃子,英文中通常称为印度醋栗或印地语中的 amla,是印度次大陆最重要的药用和食用植物之一。果实可食用,药用广泛,在传统和民间医学系统中都有广泛的应用。科学研究表明,余甘子能有效预防/缓解乙醇、对乙酰氨基酚、四氯化碳、重金属、赭曲霉毒素、六氯环己烷、抗结核药物和铁过载引起的肝毒性等肝毒素的毒性作用。余甘子还被报道对肝功能有益,能减轻高血脂和代谢综合征。余甘子对动物模型研究中的化学诱导肝癌发生具有保护作用。此外,槲皮素、没食子酸、柯里拉京和鞣花酸等植物化学物质也被报道能抵抗对乙酰氨基酚、微囊藻毒素、半乳糖胺和脂多糖的细胞毒性作用。余甘子的保肝作用似乎是通过其自由基清除、抗氧化、抗炎和调节外来物质解毒过程和脂质代谢来介导的。
