If you are already feeling like going into hibernation mode, valerian can help you. Valerian is a flowering plant that is native to Europe and Asia. Its uses are well-documented throughout history; from Hippocrates to Culpepper. Known best as a sleep aid, valerian can also help with anxiety. It has a compound in it called valerenic acid that is believed to work on receptors that enhance GABA in a similar way as sedative medications. It is often referred to as “nature's Valium”and is a wonderful remedy for general stress.
Native Americans used it to heal ulcers and wounds, as well as treating coughs.
The smell and taste of valerian is pretty unique and there's really nothing that mimics it, in that regard. The only way to know what it tastes like is to try it! Some people think it smells like dirty socks, others describe it as deeply floral.
It is best not to take large doses of valerian over an extended period of time. There is a very small percentage of the population that actually has a reverse reaction to valerian and are highly stimulated, therefore it's best to start with a small dose and see how you react to it.
