Recent studies have attempted to popularize its use as a preliminary treatment for male infertility and impotence problems.
Studies completed so far support that W. somnifera may possibly be beneficial for easing drug withdrawal symptoms, reducing anxiety. In a large clinical trial, ashwagandha reduced levels of the hormone cortisol by up to 26% while maintaining already normal blood sugar levels and lipid profiles. Subjects who took the standardized ashwagandha extract reported improvements in energy, Sleep and well-being, as well as diminished fatigue.
