RESUMEN
This study aimed to evaluate the effect of Cynara cardunculus leaf ethanol extract on inflammatory and oxidative stress parameters in the hypothalamus, prefrontal cortex, hippocampus, striatum, cerebral cortex and liver of high-fat diet-induced obese mice. Food intake, body weight, visceral fat weight, and liver weight were also evaluated. Male Swiss mice were divided into control (low-fat purified diet) and obese (high-fat purified diet) groups. After 6 weeks, mice were divided into control + saline, control + C. cardunculus leaf ethanol extract, obese + saline, obese + C. cardunculus leaf ethanol extract. Cynara cardunculus leaf ethanol extract (1600 mg/kg/day) or saline was administered orally for 4 weeks. Brain structures (hypothalamus, hippocampus, prefrontal cortex, striatum and cerebral cortex) and liver were removed. Treatment with C. cardunculus leaf ethanol extract did not affect body weight but did reduce visceral fat. Obesity can cause inflammation and oxidative stress and increase the activity of antioxidant enzymes in brain structures. Treatment with ethanolic extract of C. cardunculus leaves partially reversed the changes in inflammatory damage parameters and oxidative damage parameters and attenuated changes in the antioxidant defense. The C. cardunculus leaf ethanol extract benefited from the brains of obese animals by partially reversing the changes caused by the consumption of a high-fat diet and the consequent obesity. These results corroborate those of studies indicating that the C. cardunculus leaf ethanol extract can contribute to the treatment of obesity.

Introduction: Obesity is defined as an excess of accumulation of fat that can be harmful to health. Storage of excess fat in the adipose tissue triggers an inflammatory process, which makes obesity a low-grade chronic inflammatory disease. Obesity is considered a complex and multifactorial disease; hence, no intervention strategy appears to be an ideal treatment for all individuals. Therefore, new therapeutic alternatives are often studied for the treatment of this disease. Currently, herbal medicines are gaining ground in the treatment of obesity and its comorbidities. In this context, much attention is being paid to Cannabis sativa derivatives, and their therapeutic functions are being widely studied, including in treating obesity. Objective: Highlight the pharmacological properties of Δ9-tetrahydrocannabivarin (THCV), Δ9-tetrahydrocannabidinol (THC), and cannabidiol (CBD), the predominant isolated components of Cannabis sativa, as well as its therapeutic potential in the treatment of obesity. Methods: This is a narrative review that shows the existing scientific evidence on the clinical application of Cannabis sativa as a possible treatment for obesity. Data collection was performed in the PubMed electronic database. The following word combinations were used: Cannabis and obesity, Cannabis sativa and obesity, THCV and obesity, THC and obesity, CBD and obesity, and Cannabis sativa and inflammation. Results: Evidence shows that Cannabis sativa derivatives have therapeutic potential due to their anti-inflammatory properties. In addition, people who use cannabis have a lower body mass index than those who do not, making the plant an option to reduce and reverse inflammation and comorbidities in obesity. Conclusion: It is concluded that phytocannabinoids derived from Cannabis sativa have therapeutic potential due to its anti-inflammatory, antioxidant, and neuroprotective properties, making the plant a study option to reduce and reverse inflammation and comorbidities associated with obesity.
