This herbal supplement is often used for relaxation and sleep. The effectiveness is questionable but the main problem is an offensive odor which was so strong the entire cabinette where the closed bottle was stored wreaked of the product. Once the herb was swallowed there was no adverse odor or taste but it was difficult to get down due to the foul smell.
I have not tried any other brand of Valerian root but would be leary of this potential problem.
