Spending time in the forest has been scientifically proven to significantly boost immunity. Why? This is partly due to the aromatic compounds emitted by plants. These compounds are a part of its immune system designed to protect it from pathogens. Now when we distill a conifer tree for its essential oil we can use it to support our own immunity. Diffusing essential oils is a great way to utilize the forest's protection & strength. Really great during cold and flu season!
