Using Old Essential Oils: Frankincense and Other Essential Oils

Essential oils like frankincense can be a valuable addition to any aromatherapy routine, but their longevity can sometimes be a concern. Can an essential oil that is three years old still be used, or is it past its prime and could it harm you? In this article, we will explore the shelf life of frankincense and other essential oils, common storage practices, and how to determine whether an old oil is still safe to use.

Frankincense Essential Oil: Can It Still Be Used?

Frankincense essential oil, like all essential oils, has a shelf life. While some oils can last for decades if stored properly, others begin to lose their potency after a few years. The specific age and storage conditions of your 3-year-old frankincense oil are crucial factors in determining its usability.

Essential oils, such as Myrrh, Sandalwood, and frankincense, typically have a shelf life of several years. For instance, sandalwood essential oil can last for a few years and can still be used, as long as it was stored in a cool, dry place. However, the oil’s age at the time of distillation and the manner in which it was stored can impact its quality and usability.

Factors Affecting the Shelf Life of Essential Oils

There are several factors that can affect the shelf life of your essential oils, including:

Distillation Age: Essential oils from complementary herbs, such as cypress, may have a shorter shelf life due to their high concentration of volatile compounds. Storage Conditions: Proper storage is crucial to maintaining the quality of essential oils. Keeping them in a cool, dark place helps to preserve their potency. Use: How you intend to use the oil also matters. If you're planning to use it topically on the skin, even a diluted solution could potentially cause skin sensitization if the oil is oxidized.

Proper Storage of Essential Oils

Proper storage can significantly extend the shelf life of essential oils. Here are some best practices:

Cool, Dark Place: Store essential oils away from direct sunlight and heat sources, as these can cause the oils to degrade more quickly. Airtight Containers: Make sure all essential oils are stored in airtight, dark glass bottles to protect them from light and air exposure. Refrigeration: If an oil is particularly sensitive, consider refrigerating it to further extend its usability.

True Sandalwood and its Longevity

True sandalwood, specifically Santalum album from India, has an impressive shelf life when stored properly. One notable example of this is a batch of sandalwood I received back in 2002. A customer bought an ounce of it for her then 10-year-old son's future wedding, with the assumption that it would be used when he got married. To this day, the sandalwood remains in excellent condition, highlighting its longevity when stored under proper conditions.

Common Misconceptions About Essential Oil Shelf Life

It's important to note that not all essential oils are created equal, and their storage life can vary significantly. For instance, peppermint oil typically has a shelf life of 3 to 4 years when stored properly. However, these recommendations are only valid if the oil was stored in a cool, dark place with tightly sealed containers.

If the oil has not been well stored, use it only in low concentrations in a diffuser and avoid direct topical application. I can speak from personal experience—peppermint oil from an unreliable supplier once caused an severe eczema outbreak, which drove me to obtain certification as an Aromatherapist.

Conclusion

In conclusion, while 3-year-old essential oils can still be used with proper storage and handling, it's essential to consider the specific factors that can affect their longevity. By following best practices for storage and use, you can ensure that your essential oils remain potent and beneficial for years to come.
