Effect of coriander seed extract on body weight levels
Through Fig 1 the statistical analysis shows the effect of sugar levels on the first and last day of the experiment, The weight of the animals that were infected with diabetes decreased on the last day when compared to the first day, while for the animals that were infected with diabetes and treated with Coriander Seed Extract, we notice an increase in weight compared to the weight on the first day.
The effect of coriander seed extract on liver function
As illustrated in Fig 2, there was statistically significant elevation in ALT and AST levels within the diabetic (Gp3) laboratory animals compared to the normal control. Conversely, ALT and AST activity in the diabetic(s) treated with the coriander seed extract (Gp4) decreased as compared to Gp3.
The effect of coriander seed extract on kidney function tests
The study results recorded on a Fig 3 demonstrate an overall improvement in kidney function among all tested groups. The diabetic group (Gp3) of animals exhibited a significant elevation in urea and creatinine levels compared to animals from both the control groups (Gp1 and Gp2). Additionally, when comparing the diabetic animals (Gp3) to the animals treated with coriander seed extract (Gp5), there was a significant drop in both urea and creatinine levels for the animals receiving coriander seed extract.
Diabetes is a major health issue, with an estimated 366 million people globally predicted to have the disease by 2030, up from 171 million in 2000
(Wild et al., 2004; Guzman-Vilca et al., 2025;
Al-Saeedi et al., 2026:
Al-Obaidi et al., 2022).
Important organs for regulating blood glucose levels include the kidney and liver. Diabetes results in significant changes to the liver and pancreas, which compromise glucose metabolism and homeostasis (
Lema-Pérez et al., 2021;
Gerich et al., 2010).
Diabetes induced chronic and permanent hyperglycemia leading to excessive oxidative stress compromising the antioxidant defense mechanism and increasing the production of additional free radicals in preclinical models (
González et al., 2023;
Al-Obaidi et al., 2022;
Al-Dulimi et al., 2025).
Because of oxidative stress, alloxan has strong toxic effects on islet β cells, which leads to pancreatic β cell failure. Alloxan caused hyperglycemia in this study along with significant pathological alterations in the islets of Langerhans, such as necrosis, degeneration and hypocellularity
(Robertson et al., 2006).
Our study agrees with those who conducted numerous experiments on the role of medicinal plants in treating or preventing diabetes in laboratory animals. Among their recommendations was that further experiments be conducted on the role of plants in influencing diabetes
(Ighodaro et al., 2017).
Alloxan-injected rats have been shown to lose weight after thirty (30) days of being diabetic (Fig 1). The weight loss observed in these rats is consistent with the results obtained from studies by
Maithili et al., (2011) and
Solikhah et al., (2021), as diabetes is known to cause weight loss in rats. The values of ALT and AST activities and urea and creatinine concentrations (Fig 2 and 3) all significantly increased in the diabetic (alloxan-treated) groups of rats, confirming the greater risk for rats with diabetes to have abnormalities in liver and kidney function tests, as shown in
El Batran et al. (2006) and
Adesokan et al. (2009).
When treating diabetic laboratory animals in the fourth group with coriander seed extract, we noted in (Fig 1) a clear improvement in the weight levels of laboratory animals on the final day when compared to the third group. In addition, the results reported here support the findings of both
El-Hennamy et al. (2025) and
Elbatawy et al. (2025).
We noted in (Fig 2 and 3), the fourth group that was treated with coriander seed extract, a high significantly p≤0.05 improvement in liver and kidney functions in laboratory animals when compared to the third group. The findings of this presented data correspond with the results obtained from two studies by
Hassan et al. (2022) and
Nisa et al. (2025) documenting the nutritional effectiveness associated with coriander seeds and suggest the need for continued experimental evaluation of this plant.
