There are two ways that essential oils can enter the body to create an effect: they can either be absorbed through the skin or inhaled through the nose. Through the skin, the molecules enter through the hair follicles, sweat glands and fat molecules on the skin, entering your lymphatic and blood systems to get circulated around your body, going to the places they are needed most. Inhaling an essential oil gets the essential oil molecules into your body via your olfactory system (sense of smell) and limbic system (the emotional part of your brain) – going to the brain and your respiratory system. Once in the body, they work their way to where they are needed and where they can begin to trigger healing: in a similar way to how taking a pain-relieving tablet works.

I like to help people find unique ways to do things that will save time & money — so I write about "outside the box" Household Tips and Life Hacks that most wouldn't think of. I'm super-organized. And I LOVE to clean! I even enjoy doing laundry (but not ironing). I’m also a lifelong dog owner — so I often share my favorite tips for living with dogs inside your home (like smart home design choices and dog-friendly cleaning & decorating ideas). Career-wise, I've been sharing my best ideas with others by blogging full-time since 1998 (the same year that Google started… and before the days of Facebook and YouTube). Prior to that, I worked in Higher Ed over 10 years before switching gears to pursue activities that I'm truly passionate about instead. For example, I've worked at a vet, in a photo lab, and at a zoo — to name a few. I enjoy the outdoors via bicycle, motorcycle, Jeep, or RV. When I’m not cleaning, organizing, decorating, or fixing something… you'll find me at the corner of Good News & Fun Times as publisher of The Fun Times Guide (32 fun & helpful websites).

Cumin oil, which is safe to use in your food, can cause blisters if you put it on your skin.  Citrus oils that are safe in your food may be bad for your skin, especially if you go out into the sun. And the opposite is true, too. Eucalyptus or sage oil may soothe you if you rub it on your skin or breathe it in. But swallowing them could can cause a serious complication, like a seizure.
DO: Learn to compare apples to apples when shopping for oils. Anise, Lavender, Bay, Cedarwood, and Eucalyptus are examples of the common names of plants used to create essential oils. There, however, are different varieties of each of these plants. To differential these varieties, the botanical name (also referred to as the Latin name) is used to tell them apart. For instance, two different oils are referred to as "Bay essential oil," yet they come from two different plants. The properties and aroma of each oil do differ as does the general cost between the two. It, therefore, is important to pay attention to the botanical name. In the case of Bay, the common botanical names for the two oils used in this example are Pimenta racemosa and Laurus nobilis.

And a 2014 study involving 82 participants evaluated the effectiveness of aromatherapy for elderly people with chronic pain and symptoms of anxiety and depression.

With its bright and joyful aroma, Lemon oil benefits skin and hair as much as its aroma enhances your environment.

This oil is a key ingredient in many hair and skin care products. Because citrus oil can cause photosensitivity, avoid applying Lemon to exposed skin before spending time outside.

Aromatherapists, people who specialize in the practice of aromatherapy, utilize blends of supposedly therapeutic essential oils that can be used as topical application, massage, inhalation or water immersion. There is no good medical evidence that aromatherapy can either prevent, treat, or cure any disease.[4] Placebo-controlled trials are difficult to design, as the point of aromatherapy is the smell of the products. There is disputed evidence that it may be effective in combating postoperative nausea and vomiting.[5][6]
