Overall, this is not directly related to Feng Shui. Frankly, I am not familiar with this area i.e. Aromatherapy. Perhaps, you can find out more from Global Shops like the " Body Shop " etc... In Feng Shui, smells can be classified as under one of the Five Elements. For example, peppery smell goes towards the Fire element etc... I have not done any research into this area so unable to comment further. Warmest Regards Cecil is there any information on what aromas are associated with certain elements and colors. what is the best aroma for a bedroom, bathroom, kitchen, living room?
