If you've got essential oils that you can't remember when you opened, there are some other indications that can tell you it may be time to throw them out: If there's a change in the smell. If its color has changed or if it's gone cloudy. If the consistency is thinner or thicker than before.

When you're buying oils, they should smell pleasant and natural. Trust your nose. If you detect a twinge of alcohol, or if an oil smells less like aromatherapy and more like kitchen cleaner, steer clear.

Incidentally, vegetable oils also oxidize, and we call this “going rancid”. As an essential oil oxidizes its smell changes a little, some brightness/freshness disappears, though you may not realize this unless you compare with a new, fresh oil. Citrus oils sometimes go cloudy at the same time as oxidizing.

Diffusion guidelines
Intermittent means 30-60 minutes on, then 30-60 minutes off. This is because our body, especially our nervous system, habituates after this length of time. With continuous diffusion, while benefits do not increase, there is evidence that the body becomes stressed in various ways.

Between 3 to 5 drops of an essential oil are recommended to use in a diffuser, if the diffuser's size is 100 ml. So 3 drops is a standard amount that can be used as a trial, if you are using an aroma diffuser for the first time.
Take a whiff
Open the bottle and smell the contents. If the smell underwhelms you or if it feels like a cheap perfume, know that it's a fake. Training your nose may take a little time, but it's the best way to identify pure essential oils. Remember: high-grade essential oils give off a natural and soothing scent.
