The essential oils are very concentrated, thus having a very strong aroma when pure. For the aromatization of environments, you can add one drop in the environment, to each one meter, which will be enough. Another possibility is to dilute about 10 ml of pure essential oil in 1 liter of water, moisten a cloth with this solution and pass in the desired environment; or apply a few drops in a diffuser. Avoid the exaggeration of the essential oil for aromatization, because, for possessing in high concentration, they can cause nausea and discomfort when there is excessive exposure.

Compress

Many people use the compress to relieve and accelerate recovery from this impact or injury, but did you know that some types of essential oils can help even more in this recovery? Some oils have analgesic and stimulating properties of peripheral circulation, so they can be used for the treatment of muscle contusion. From two to three drops of essential oil in the compress is enough to increase the effectiveness and contribute to muscle relaxation.

Massage

The essential oils are widely used in massages, thanks to their analgesic, relaxing, and stimulating properties of peripheral circulation. It is good to remember that the essential oil, because it is very concentrated, must be diluted in some carrier oil, like vegetable oil, to avoid possible skin irritations and adverse reactions. About 35 drops for every 100 ml of vegetable oil is a good proportion for application in massages.

Inhalation

Some essential oils can improve the respiratory system (in cold situations, for example), besides providing a possible psychological relaxation. Adding a few drops of the oil (about four) to a container of hot water can help the breathing of the person who is going to inhale.

Cleaning

Several types of essential oils carry compounds that have antiseptic action. Therefore, they can be used in cleaning, killing several miniature organisms. Some pure drops can be applied on a cloth that is passed in the desired area, however, the drops must be well spread for the smell not to get too strong.

Hair

The essential oils can also be used in hair treatment, being mixed a few drops (ten) in shampoo (100 ml) or vegetable oil (100 ml), and massaging the mixture on the scalp. They can be used for dry hair treatment (cedar and sage essential oils), oily hair (cedar and lemon oils), dandruff treatment (rosemary and melaleuca), and hair loss (rosemary and cedar).

In the shower, three drops can be applied to just one corner of the box, because if more than this is added, the moisture generated in the bath can concentrate a lot and cause discomfort and nausea. In the bathtub, about ten drops can be added, because they will be well diluted by a large amount of water in the bathtub.

Some essential oils can be ingested and provide health benefits, but safety depends very much on each type of essential oil, application, and the reaction of the person’s body. Never ingest essential oil without being sure about its safety and indicated quantity, because they are extremely concentrated.
