What is the rate of microcirculation enhancement produced by Nicomenthyl?

A Doppler Laser Blood-flow Velocity Test has been carried out on twenty volunteers of both sexes, using a topical preparation containing 3% of Nicomenthyl, compared to a negative control (placebo). Increases in microcirculatory flow values reached remarkable levels, up to nearly 150% at 30 minutes and 90% at 60 minutes after application, without any irritating or sensitizing effects.
