• Whether you are practicing aromatherapy or simply trying to freshen up your home, using a reed diffuser is a great way to enjoy your favorite scents. Reed diffusers are quite easy to make at home by putting reed sticks within a jar containing an essential oils mix. The oils are effectively “sucked” up the channels in the reeds, and when they reach the top of the reeds, the scent is dispersed throughout the room. As long as you have your essential oils and base oils, all you need are reed sticks as well as a long vase or similar container with a narrow opening.
