This is an all natural unisex Aromatherapy roll on that I created for enhancing Mental Clarity and improving Brain Function. This is a great item to use while studying, taking an exam, overcoming procrastination and mental blocks, starting new projects or completing projects, playing chess or golf, and much more. Rosemary and Peppermint essential oils are two of the main ingredients. These oils are known to speed up synaptic transmissions. The scent of this oil is very uplifting, fresh, clean and herbaceous. Other essential oils include Lavender, Lemon, Pink Grapefruit, Spearmint, Basil and Black Pepper. Patchouli is included as a base note or fixative to give it lasting power. This roll on is perfume strength so stronger than the typical Aromatherapy Roll on. Since this roll on is made with stimulating essential oils it is best when used for special projects rather than daily. I would also avoid using it at night before trying to sleep. The essential oils are in a Fractionated Coconut oil base, and the total volume is 0.35 oz.
