If you are looking for a natural sleep aid to help you stay horizontal through-out the night, we've got news for you. The traditional herbs used in the West for help sleeping are valerian and hops. Maybe you've heard of them. In one of the most thoroughly conducted research studies on these herbs, it was discovered these herbs only work when extracted together.
These top researchers in Switzerland conducted a randomized, double blind, placebo controlled study to demonstrate the fixed combination of chemical constituents from the plants. What the researchers found is that only when these two herbs are used in a fixed combination at 500 milligrams valerian extract siccum to 120 milligrams hops extract siccum, did they reduce sleep latency. The valerian extract alone was no better than a placebo. Always check product dosages for the best results.
Traditional Chinese Medicine has a long history of using herbs together. When using Chinese herbs as an over-the-counter sleep aid, either mixed at a Chinese pharmacy or in prepackaged packets like our iSleep Herb Pac, it is most common to have herbs combined together to create a synergistic action that is much more effective than any one herb working alone. Chinese herbs are always used in combination formulas for the very same reason this study demonstrates. They simply work better, together. Studies can prove this, but it is really history of over a thousand years of using herbs cooked together which has provided this knowledge.
