Here are a few helpful hints in regards to the use and storage of essential oils:
Always buy essential oil bottles which are amber in color. Never buy plastic bottled oil.
Make sure you check the date of manufacture before buying. Shelf life is short enough, so you don t want essential oil which expires soon.
Never store the oil in direct sun light.
If all essential oils are exactly the same price, steer clear. For example, Rose oil will always be more expensive than Lavender or Rosemary.
If your oil is already diluted, make sure to find out what carrier it has in it.
