I have found a couple of herbal teas that can help a person wind down and get some sleep.
The first one is Sleepytime Tea by Celestial Seasonings. It has all kinds of great herbs in it to help enhance rest.
The other one that is really great, is call "Get Some Zzz's". This is a tea made by the Republic of Tea, in their "Be Well Red Teas" line. The main herbs in this tea are Oragnic Rooibos leaf, Orange peel, Spearmint leaf, Chamomile flowers, Passion Flower herb, and Stevia leaf. It also has valerian root extract in it.
Try these a little bit before bedtime or anytime you wish to rest. It is an all natural way to help your body get the rest it truly needs.
