Abstract

Black garlic is the product of fermenting fresh garlic (Allium sativum L.), which is rich in bioactive compounds such as S-allyl cysteine, polyphenols, and flavonoids with antioxidant and anti-inflammatory activities. These compounds have potential as nephroprotectors against gentamicin-induced kidney damage. This narrative review seeks to consolidate evidence regarding black garlic's nephroprotective mechanisms, dose-response patterns in gentamicin-induced nephrotoxicity, and its impact on body weight variations. Literature was sourced from PubMed, ScienceDirect, Google Scholar, and Sinta, covering the publication period 2020–2025, using the keywords black garlic; nephroprotective; nephrotoxicity; and Allium sativum. The results of the review indicate that S-allyl cysteine and flavonoids act by inhibiting ROS and increasing SOD, GPx, and CAT; suppressing NF-kB accompanied by a decrease in TNF-alpha and IL-6; regulation of the Bcl-2/Bax ratio along with caspase-3 suppression, plus enhanced renal hemodynamics through nitric oxide.

Abstract

Acute kidney injury can be triggered by gentamicin-induced nephrotoxicity due to drug accumulation in renal cortical epithelial cells, which increases reactive oxygen species (ROS) and causes oxidative stress, as reflected by elevated blood urea levels. Black garlic (Allium sativum L.) contains S-allyl cysteine (SAC), a potent antioxidant that may neutralize oxidative stress and protect the kidney. This narrative review aims to evaluate the effectiveness of black garlic extract in lowering blood urea levels across various animal models of nephrotoxicity. A literature search was conducted on PubMed, Scopus, and Google Scholar for studies published between 2020 and 2025 using the keywords "black garlic", "blood urea", and "nephroprotective". A total of 3 relevant articles meeting the inclusion criteria were analyzed in this review. The results show that administration of black garlic extract was consistently associated with reduced blood urea levels toward normal values in animal models induced by gentamicin as well as other nephrotoxic agents such as cisplatin and sodium benzoate. This blood urea reduction positively correlated with improved renal histopathology, characterized by decreased tubular necrosis and inflammatory cell infiltration. Additionally, black garlic extract increased the activity of endogenous antioxidant enzymes, including superoxide dismutase, glutathione peroxidase, and catalase, while decreasing malondialdehyde levels as a marker of lipid peroxidation. Furthermore, black garlic extract also reduced caspase-3 expression, indicating inhibition of the apoptotic pathway. In conclusion, black garlic extract demonstrates potential as a nephroprotective agent in lowering blood urea levels in various nephrotoxicity models through antioxidant, anti-inflammatory, and anti-apoptotic mechanisms.
