The scent is amazing it smells just like sweet citrus. Grapefruit oil is used for many things like weight loss, antioxidant, disinfectant, tonic and it also helps with stiff and cramps in the muscles. I use this for my homemade cleaners and also put one or 2 drops in a glass of water to help suppress my appetite. You can use this in a diffuser to give your room a refreshing smell. This comes in a dark colored glass bottle. All you really need is a few drops. I received this product free in exchange for my honest review.
