You should know that aromatherapy is easy and something you are already probably practicing. If you use ginger to help you with an upset stomach or drink chamomile tea to relax at night, you are already practicing aromatherapy. It’s no more complex than using a eucalyptus based product to help you clear your sinuses.
Essential oils or incense can enhance the qualities of scents, giving them a greater degree of efficacy. But generally, the practice is little more than what you are probably doing already. With a small amount of knowledge, you can continue to use aromatherapy more effectively, and address specific issues with the scents that can assist you with alleviating them.
Vanilla, for example, is great for insomnia, lemon can help you reduce stress, orange has even been shown to combat PTSD. Along with these emotional properties, the right aromas can reduce pain or lower blood pressure.
