Moreover, a fenugreek seed extract was observed to decrease spontaneous fat intake in overweight individuals, resulting in a small yet notable reduction in dietary fat consumption, which could aid in weight control. While these findings show promise, more research is necessary to fully grasp how blue fenugreek specifically affects weight loss and the underlying mechanisms.
4. Soothing Inflammation
Blue fenugreek, although not directly studied in the papers provided, is closely associated with Trigonella foenum-graecum and Trigonella gharuensis. These two have shown remarkable anti-inflammatory properties. Studies reveal that Trigonella foenum-graecum seeds oil (TgSO) can reduce inflammation and angiogenesis by lowering TNF-α and increasing antioxidant enzymes like superoxide dismutase (SOD) and catalases (CAT). In vivo studies support this by demonstrating that TgSO significantly decreases swelling in different models and displays antiangiogenic effects, confirming its traditional use as an anti-inflammatory herb. Similarly, extracts from Trigonella gharuensis can hinder inflammation in various in vivo models, hinting at the suppression of autacoids, which are mediators of inflammation. These discoveries imply that blue fenugreek, due to its chemical similarities with these species, might also have calming anti-inflammatory properties.
5. Improve sexual health
Studies on the closely related Trigonella foenum-graecum have shown positive results in improving sexual health.
