Green oat extracts contain potentially psychoactive phytochemicals that have been shown to improve cognitive function following a single dose. This study investigated the effects of a single dose and four-week administration of a novel herbal extract (cognitaven) on cognitive function, mood, and changes in psychological state during a laboratory stressor. The study found that a single dose of 1290 mg and supplementation for four weeks with both 430 mg and 1290 mg green oat extract improved performance on working memory and multitasking tasks, and the highest dose also decreased the physiological response to stress. There were no treatment-related effects on mood. These results show that chronic supplementation with green oat extract can benefit cognitive function and modulate the physiological response to stress.
Viola tricolor Linn. is a traditional medicine used for its cardio-protective and anti-hypertensive effects. The study aimed to evaluate its effects in in vitro and in vivo studies. The crude extract and its fractions were tested on rabbit atria and aorta, and the blood pressure was measured in normotensive ketamine-diazepam anesthetized rats. The results show that Viola tricolor L. has cardio-relaxant, vasorelaxant, hypotensive, and cardioprotective effects mediated through Voltage dependent L-type calcium channels blockage. The study suggests that Viola tricolor L. can be used to treat cardiovascular disorders.
