NCT04167449

Brief Summary

A prospective, randomized, double blind, placebo-controlled study to determine if a hydroponically-cultivated red ginseng preparation is superior to conventionally grown ginseng and placebo for positively affecting electrical activity of the brain during performance of various cognitive tasks.

Outcome Measures

Primary Outcomes (3)

  • Change in baseline electrical activity of the brain as measured by Quantitative Electroencephalogram for the hydroponic Korean red ginseng preparation versus conventional ginseng and placebo

    Responses of electric brain activity as spectral power in 17 different brain regions within 6 specially defined frequency ranges (delta, theta, alpha1, alpha2, beta1 and beta2) during cognitive performance: d2-test for attention (d2-Test).

    Four weeks

  • Change in baseline electrical activity of the brain as measured by Quantitative Electroencephalogram for the hydroponic Korean red ginseng preparation versus conventional ginseng and placebo

    Responses of electric brain activity as spectral power in 17 different brain regions within 6 specially defined frequency ranges (delta, theta, alpha1, alpha2, beta1 and beta2) during cognitive performance: memory test (ME-Test).
