Study summary

To assess the cardiac effects of an energy drink and Panax Ginseng in healthy volunteers.

Read the detailed description

Energy drinks are composed of a variety of ingredients such as caffeine, taurine, and panax ginseng amongst others. The safety and efficacy of these ingredients individually and in combination need further exploration. This study is designed to assess the electrocardiographic and blood pressure effects of energy drinks and panax ginseng in healthy volunteers.
