Pomegranate and its active components can protect against natural and chemical toxic agents, impacting mechanisms such as oxidative stress, inflammation, apoptosis, and liver or cardiac function regulation.
This paper is a review of various in vivo and in vitro studies focusing on pomegranate (Punica granatum) and its active components, including ellagic acid and punicalagin, and their protective effects against toxic substances. The articles were sourced from multiple databases like Web of Sciences, Google Scholar, PubMed, and Scopus spanning all available time periods until the end of September 2022.
The research indicates that pomegranate and its constituents have showcased protective effects against both natural toxins, such as aflatoxins and endotoxins, and chemical toxicants like arsenic, diazinon, and carbon tetrachloride. This protection is attributed to the preventive mechanisms activated against oxidative stress, reduction of key inflammatory mediators, modulation of apoptosis, and signaling pathways associated with cellular growth. Additionally, these components appear to aid in the improvement of liver and cardiac function through the regulation of key enzymes.

Experimental Study Chemotherapy Oxidative Stress Pomegranate
In this study, the impact of pomegranate (L.) juice extract (PPJE) on skin cells treated with 5-Fluorouracil (5-FU), an antineoplastic agent, was evaluated. This involved assessing the extract's ability to inhibit the release of reactive oxygen species and enhance the cellular antioxidant response of the treated skin cells. Specific attention was given to observe the overexpression of cytoprotective enzymes such as heme oxygenase-1 and NAD(P)H dehydrogenase [quinone] 1 after the introduction of PPJE.
The results indicated that PPJE indeed blocked the formation of nitrotyrosine and reduced the release of cytokines, therefore indicating a dampened inflammatory response. Furthermore, it was revealed that the extract could inhibit the nuclear translocation of p65-NF-κB, a key regulator of inflammation. The study also pointed out that PPJE could curb apoptosis in cells treated with 5-FU, whilst fostering wound repair. The overall findings suggest that PPJE holds potential as a supplementary agent for managing oxidative and inflammatory issues associated with chemotherapy-induced skin side effects.
