Brief summary: A pilot investigation into the stress relieving properties of Vitano® which will assess the following hypotheses

Individuals exposed to Vitano® will demonstrate diminished blood pressure and heart rate responses to mental stress compared to individuals in the control condition

Physiological recovery (BP, HR and cortisol) from mental stress will be enhanced in individuals exposed to Vitano® compared to individuals in the control condition

Vitano® will have positive effects on cognitive functioning.

Subjective ratings of stress will be reduced in individuals exposed to Vitano® compared to individuals in the control condition

There will be a significant improvement in subjective well-being in individuals taking Vitano®.

* Clinically significant hepatic or renal abnormality as determined by laboratory tests.
