Potential restorative effect of silymarin on liver histoarchitecture on paracetamol-induced in hepatotoxicity, in adult albino rats

Background: Paracetamol is one of the most common pain relievers you’ll find in any medicine cabinet. Worldwide its often used for fevers or everyday aches without a second thought. But while it’s generally safe, taking too much can seriously harm the liver, something many might not realize. Otherwise, natural remedies offer potential remedies like silymarin, an extract from milk thistle. This herbal compound isn’t just a supplement; studies suggest it fights oxidative stress and even helps repair damaged cells. Objective of this study was to determine the histo-restorative effects of different doses of silymarin milk thistle on liver histo-architecture on paracetamol-induced hepato-toxicity among adult albino rats. Methods: A total of 24 rats, splitting them into four groups. One group got a high, toxic dose of paracetamol alone; another stayed untreated as a control. The remaining rats were all given paracetamol first to induce liver injury, then divided into three subgroups receiving low, medium, or high doses of silymarin. After the treatment period, their liver tissues were extracted and studied under a microscope, using standard staining techniques to assess any recovery. Results: High dose of paracetamol induced liver toxicity. Upon administration of high dose of silymarin milk thistle, there was histo-restoration of liver architecture with evenly distribution of hepatocytes and reduction and vacuolation of the central vein in relation to the control group. Conclusions: These findings showed that high dose (600 mg/kbwt) of silymarin milk thistle was found to have restorative effects and restored the liver histo-architecture to near normal.
