Silymarin is a mixture of polyphenolic flavonoids isolated from milk thistle (Silybum marianum) with anticancer activities reported for several organ sites. The present study tested the efficacy of dietary silymarin against mammary carcinogenesis in two rodent models. In the Sprague-Dawley rat model, female rats were fed a purified diet supplemented with none, 0.03, 0.1, 0.3 or 1% (w/w) of sily...

BACKGROUND The first line anti-tuberculosis drugs isoniazid (INH), rifampicin (RIF) and pyrazinamide (PZA) continues to be the effective drugs in the treatment of tuberculosis, however, the use of these drugs is associated with toxic reactions in tissues, particularly in the liver, leading to hepatitis. Silymarin, a standard plant extract with strong antioxidant activity obtained from S. marian...

Solar ultraviolet (UV) radiation is a well recognized epidemiologic risk factor for melanoma and non-melanoma skin cancers. This observation has been linked to the accumulation of UVB radiation-induced DNA lesions in cells, and that finally lead to the development of skin cancers. Earlier, we have shown that topical treatment of skin with silymarin, a plant flavanoid from milk thistle (Silybum ...

BACKGROUND Hepatitis is a common adverse effect of antituberculosis drugs. Silymarin prevented drug-induced hepatoxicity in animals with anti-oxidative mechanisms but its effect in human has been unknown. We aimed to evaluate the efficacy of silymarin for preventing antituberculosis-drug induced liver injury (antiTB-DILI) in patients with tuberculosis. METHODS A double-blind randomized placeb...

INTRODUCTION Diabetic nephropathy is the major cause of end-stage renal disease worldwide. Silymarin is a flavonoid mixture obtained from Silybum marianum. Various preclinical and clinical studies have revealed that it has antidiabetic activity. The objective of this study was to evaluate the effect of silymarin on type 2 diabetic nephropathy in rats. MATERIALS AND METHODS Non-insulin-depende...

In chronic liver diseases caused by oxidative stress (alcoholic and non-alcoholic fatty liver diseases, drug- and chemical-induced hepatic toxicity), the antioxidant medicines such as silymarin can have beneficial effect. Liver cirrhosis, non-alcoholic fatty liver and steatohepatitis are risk factors for hepatocellular carcinoma (HCC). Insulin resistance and oxidative stress are the major patho...

Silymarin, which derived from the milk thistle plant (silybum marianum), has been used for centuries as a natural remedy for diseases of the liver and biliary tract. Considering the therapeutic potential to liver disease, we tested efficacy of silymarin on hepatic steatosis with a high fat diet (HFD)-induced mouse model of non-alcoholic fatty liver disease (NAFLD), and investigated possible eff...

Silymarin, also known as milk thistle extract, inhibits hepatitis C virus (HCV) infection and also displays antioxidant, anti-inflammatory, and immunomodulatory actions that contribute to its hepatoprotective effects. In the current study, we evaluated the hepatoprotective actions of the seven major flavonolignans and one flavonoid that comprise silymarin. Activities tested included inhibition ...

Silymarin, a flavonolignan derived from Silybum marianum, possesses diverse pharmacological activities, including hepatoprotective, antioxidant, anti-inflammatory, anticancer, and cardioprotective. Although clinical trials have shown silymarin is safe at high doses (>1500 mg/day) in humans, the pharmacokinetic studies over the past three decades related to absorption, distribution, metabolism, ...

BACKGROUND Silymarin, the main flavonoid constituent element extracted from Silybum marianum possessing antioxidant activity, is already known to be able to block the NF-κB activation process and result in cell apoptosis, implicating silymarin's potential to control cancer cell growth. MATERIALS AND METHODS In this study, based upon the above assumption, silymarin was administered to a highly...
