The endocrine system consists of various glands responsible for secreting hormones that regulate metabolism, growth, reproduction, and other physiological processes. Disruptions in this system, termed endocrine disorders, are linked to numerous health issues, such as obesity, diabetes, cardiovascular diseases, and metabolic syndromes. Moreover, the significance of factors such as life stage, gender and dietary habits in influencing health risks associated with endocrine disruption cannot be overstated. Synthetic medications for these conditions often have adverse side effects like hypoglycemia and heart complications, highlighting the need for alternative treatments. Herbal and natural remedies have shown promise in managing these disorders due to their lower toxicity and minimal side effects. Phytochemicals and poly-herbal therapies are emerging as effective strategies for addressing endocrine and metabolic disorders, influencing molecular targets like AMP-Activated Protein Kinase (AMPK) and Nuclear factor erythroid-2- related factor (Nrf2). Specific disorders such as diabetes, Addison{\textquoteright}s disease, and hyperthyroidism are characterized by hormone imbalances, with molecular mechanisms involving insulin resistance, cortisol dysregulation, and thyroid dysfunction. Additionally, the role of factors such as life stage, gender, and dietary habits in modulating endocrine disruption-associated health risks is crucial. Natural products, including flavonoids, catechins, resveratrol, and terpenes, are being explored for their therapeutic potential in regulating hormone levels and improving metabolic health.

Background: Type 2 diabetes mellitus (T2DM) is a major risk factor for cardiovascular disease (CVD) development. The pharmacological treatment of T2DM can increase cardiovascular risk in diabetic patients. Carqueja (Baccharis trimera) is an antioxidant and hypoglycemic medicinal plant with promising action for T2DM non-pharmacological treatment. Objectives: The objective of this study is to investigate carqueja essential oil safety on the cardiovascular system of diabetic and non-diabetic rats. Materials and Methods: Four experimental groups were used to analyze the carqueja essential oil effects: control group (n = 5), carqueja-treated control group (n = 4), diabetic control group (n = 4), and carqueja-treated diabetic group (n = 5). T2DM was induced by hypercaloric diet followed by streptozotocin administration. Electrocardiogram parameters were used to analyze the alterations in the cardiovascular system. Results: Diabetic rats showed ventricular repolarization dysfunction with prolongation of QT and corrected QT intervals. The treatment increased ventricular repolarization duration in the control group. Conclusion: Carqueja essential oil treatment worsens ventricular repolarization in nondiabetic rats, increasing the arrhythmogenic risk.

Introduction: Kolaviron (KV), a biflavonoid extract from Garcinia kola seeds has been reported to possess anti-inflammatory, anti-oxidant, hepato-protective, cardio-protective, nephro-protective and other arrays of chemopreventive capabilities but the mechanism of action is still not completely understood. Materials and Methods: In this study, we investigated the anti-proliferative, anti-inflammatory and anti-oxidative potential of KV in cultured Vascular Smooth Muscle Cells (VSMCs). Effects of KV (25-100 μg/mL) on VSMC proliferation alone or following treatments with mitogen and proinflammatory agents Angiotensin II (Ag II, 10-6 M) and lipopolysaccharide (LPS, 100 μg/mL) and effects on NO production were determined. Cellular proliferations were determined by MTT assay, nitric oxide (NO) level was determined by Griess assay. KV dose-and time dependently attenuated VSMC growth. Results: Treatment of VSMCs with Ag II and LPS significantly enhanced proliferation of the cell which was significantly attenuated by the treatment with KV. Treatment of VSMC with LPS significantly increased nitric oxide (NO) level in the media which was attenuated by KV. These results demonstrated anti-proliferative antiinflammatory properties of KV as it clearly inhibited cellular proliferation induced by mitogens as well as LPS-induced inflammatory processes. Conclusion: Therefore, KV may mitigate cardiovascular conditions that involve cell proliferation, free radical generation and inflammatory processes such as hypertension, diabetes and stroke. However, the molecular mechanism of action of KV needs to be investigated.
