The pursuit to help Insomnia patients led researchers on a journey across the world to various parts of Europe and Asia. Historically, many countries had a far lower rate of insomnia and other sleep disorders. Researchers wondered if this could be related to their high intake of certain plants like Lavender, Copaiba, Clary Sage, and many others.
Researchers compared sleep pattern tests between healthy 40 to 90 year-olds who consumed varying quantities of these ingredients. They found those who consumed these at least "occasionally" had much higher scores than those who "rarely or never" did.
But, as the researchers found, just taking these ingredients by themselves wasn't enough. Alone, these ingredients were not powerful enough to induce a high quality sleep. So, researchers went back to the drawing board.
