This does not seem to be an extract to me. I consider an extract to be in liquid form only, but this liquid has a lot of fine particles in it as if the hops was boiled in water and strained through a leaky strainer. The particles are dense enough to clog the eyedropper. In addition, this is not a standardized product. So, it's difficult to determine how effective it is or should be. I've tried it several times before bedtime to help make me drowsy, but I've not noticed any effect. Next time I'll look for a standardized product meaning one that contains a specific percentage of active ingredients.
