If food is the first thing that comes to mind when you think of rosemary, you’ve got great taste. Rosemary, an evergreen plant with needle-like leaves and a soft, woody aroma, is most commonly known as a food seasoning, but it is also a powerful essential oil.

Natural essential oils are often used in aromatherapy, a form of alternative medicine to support health and well-being, but there are many ways to use them. Wondering how to safely use essential oils for adults? No worries, here’s everything you need to know about essential oils! Nature of science: . . Although Ohm and Barlow published their findings on the nature of electric current around the same time, little credence was given to Ohm. Barlow’s incorrect law was not initially criticized or investigated. This is a reflection of the nature of academia of the time with physics in Germany being largely non-mathematical and Barlow held in high respect in England. It indicates the need for the publication and peer review of research findings in recognized scientific journals.. (Analytical Work). (STATIC). .  .
