13. Grapefruit
Grapefruit oil is not in widespread use because most people are unaware of its excellent health benefits. The fact that it is not used regularly means that studies have not created an association between its use and any adverse side effects. However, some believe it may be associated with breast cancer development, but there is no scientific evidence.
The health benefits associated with grapefruit include preventing water retention, bloating, and are also known to help dissolve fat. It will buffer your appetite, help you lose weight, help balance your mood, reduce stress, treat acne, and have antibacterial and anti-bacterial effects.
