This natural sleep aid helps to relax and calm the mind, naturally, so you can wake up feeling rested and restored, but not drowsy.Developed by Dr. Xu, NEW Restful Sleep’s key ingredient is Astragalus—an ancient traditional Chinese herb used and documented in medical texts dating as far back as 220AD for its health-promoting effects on the spleen. In traditional Chinese medicine, stress and worry can impact the spleen which, if unsupported, can cause difficulty with turning off the mind and falling asleep. As a key ingredient, Astragalus also helps to quiet the mind, allowing the body to relax and rest, for a good night’s sleep.
