Valerian is a very popular sleep herb – it has a very long tradition of use as a warming remedy that quells the nervous system while also relaxing muscle tension and spasms. There is also a growing body of clinical research backing its use as a sleep aid (particularly helping to improve the speed at which you fall into a deep sleep – or sleep onset latency), and showing minimal side effects. Valerian seems to be most effective when synergistically combined with passionflower, lemon balm and/or hops. Valerian, passionflower and other mildly sedative herbs can be found in our Deep Sleep Tincture and in our Deep Sleep Supplements.
