Blind Leading the Blind: Essential Oils in Eye Care

green eye There has been much social media discussion recently (February 2013) about the wisdom or otherwise of putting essential oils into your eyes to treat eye problems. This arose from two web pages:

http://aromatherapyliving.wordpress.com/2013/02/12/clear-vision-with-natural-eye-drops/

The Livestrong article states: “More and more people are choosing to use alternative medicines to treat minor illnesses rather than taking a prescription. Putting essential oils in or near the eyes isn’t something that is widely known about, but there are several that can aid in the treatment of eye problems. Before using essential oils for your eyes, always contact your doctor.

Clary sage is the essential oil that is most widely used to treat vision problems. It is placed in the eye, so advice from an optometrist is important before use. Clary sage is used as a cleanser for the eyes. It can also be used to clear eye sight due to foggy vision or an injury to the eyes. Clary sage can also be used to brighten the eyes and improve vision. Finally, it can have beneficial results for people with eye issues related to aging.”

This actually dates from May 2010 but, judging from the related comments, has only recently been noticed. The statement that “Clary sage is the essential oil that is most widely used to treat vision problems” is not true, since there are no essential oils commonly used to treat vision problems. The only evidence for any essential oil treating any eye problem relates to Tea tree (Melaleuca alternifolia) oil and eyelash mites (see below). The reference to Clary sage probably derives from 17th century European herbalists, but this refers to using Clary sage seeds, or mucilage made from them, and not to Clary sage essential oil: “The seed put into the eyes clears them from motes and such like things gotten within the lids to offend them, and it also clears them from any white and red spots which may be on them (Culpeper, 1652). Another common name for Clary sage (Salvia sclarea) was “clear eye” because of this common use of the seeds, which pre-dated Culpeper by many years. “Clary” may derive from “clear-eye.”

Not only is there no evidence that any essential oil can help with vision problems, age-related or otherwise, but placing any essential oil “in the eye” is extremely dangerous advice. Almost any undiluted essential oil coming into contact with the ocular membranes will be corrosive, possibly causing scarring of the cornea, and certainly causing significant pain.

I could find no reports in the literature of ocular accidents involving single essential oils, but there are several for Olbas oil. This is a mixture of essential oils (species not specified) and menthol:

35.45% Eucalyptus oil
35.45% Dementholized mint oil
18.5% Cajuput oil
4.1% Menthol
3.7% Wintergreen oil
2.7% Juniper berry oil
0.1% Clove oil

A 2009 report from an ophthalmologist in Bristol UK, describes partial loss of corneal tissue (i.e. erosion) when a 73-year-old man dripped Olbas Oil into his left eye (he had no right eye) because he thought he was using eye drops (Figure 2). He was “considerably incapacitated.” but recovered after a week of treatment with “topical antibiotics and lubricants.” On checking, the author found that just his hospital, in the previous 18 months, had seen 12 patients who had mistakenly dripped Olbas Oil into one eye. He describes the result as a chemical burn, though he found that Olbas Oil in tears was pH neutral (most chemical burns are caused by sub-stances that are strongly acid or alkaline). All “Olbas Oil patients” recovered fully within one week following intensive treatment (Adams et al, 2009).

Olbas Oil may cause problems even when not applied directly to the eyes. The mother of a fourmonth-old boy placed several drops of Olbas Oil in his right nostril in an attempt to help his respiratory infection, not realizing that the product warns against use in infants. The child immediately showed signs of respiratory distress and was taken to the emergency room. Two hours after admission his eyes became inflamed and examination revealed bilateral superficial corneal scarring. He also had conjunctivitis and could not open his eyes. They were flushed with saline over four days and he recovered with no residual scarring (Wyllie and Alexander, 1994).

Emergency treatment
More than 65,000 work-related eye injuries and illnesses are reported annually in the USA, a “signi-ficant percentage” of these being ocular chemical burns. They require rapid treatment, and severe burns have a poor prognosis. The standard treatment is copious irrigation with saline solution for 1-2 hours. Contact lenses should not be removed initially (Peate, 2007). With essential oils, fatty oil has been suggested as an appropriate first aid treatment though the advantage of saline is that the eyes can be continually flushed and this is less easy with fatty oil.

What about diluted essential oils?
The second article describes using essential oils diluted to (by my estimation) about 3%. It includes the following advice:

“Here is a truly natural solution, which has been shown to benefit your eye health and the only one I will use. Gary Young has used this recipe for his patients at the Ecuador Clinic for macular degeneration, health issues, cataracts, and improving sight. I’ve been using it for a couple of years and love it! I started using this recipe before I had to have a vision exam in order to purchase new contacts. And I knew my vision had deteriorated from my last exam. So I put the drops in my eyes every night for about six months prior to the exam and my prescription had not changed according to their records, but I know what I was not seeing and I know what I was seeing as a result of using these drops – clearly my vision had improved! The recipe is as follows:

7-10 drops of Frankincense
7-10 drops of Rosemary
7-10 drops of Cypress
2 Tbsp of V-6
Put oils in a glass dropper bottle with a lid on it.

My experience has been that I can see much more clearly just after putting the drops in my eye so I am also going to experiment with putting a drop in my eyes in the morning (Ewald, 2012).”

“V-6” is a proprietary blend of vegetable oils. The above implies that using these oils on a daily basis is likely to have a healing effect in cases of cataract, macular degeneration, or failing eyesight. Although the article continues to describe various effects of the essential oils, none of them have any relationship with any of these conditions. So the question arises – how to weigh potential benefits against potential risks?

The word “experiment” in the above seems appropriate. Eyesight problems are difficult to treat and, once damage has occurred, recovery is not always simple. A 3% dilution may not be sufficient to cause corneal erosion, but on the other hand there is no evidence of any benefit. One concern is that the wrong dilution may be used, and the risk of this is substantial. For example, it would be easy to confuse “tbsp” with tsp,” resulting in a dilution of about 10% instead of 3%.

In a Chinese study, an ointment containing 5% Tea tree oil was used by patients whose eyelash follicles were infested with “eyelash mites” (Demodex folliculorum). The ointment was applied to the lid margins with eyes closed, daily for 4 weeks after washing the face, and resulted in considerably less itching and fewer mites. Two of the 24 patients experienced slight irritation from the ointment. The 5% concentration was arrived at after preliminary testing using various dilutions on rabbit eyes (Gao et al, 2012).

Conclusions
–Undiluted essential oils should not be applied to the eyes.
–It is rash to suggest that essential oils are commonly used to treat eye problems.
–Eye injuries and diseases are medical conditions, and any product claiming to treat them is a medicine, subject to drug legislation.
–There is currently no evidence that applying dilutions of essential oil into the eyes will be beneficial in any condition.
–Diluted (5%) Tea tree (Melaleuca alternifolia) essential oil may help eradicate eyelash mites, but it should not be placed into the eyes.

One response to “Blind Leading the Blind: Essential Oils in Eye Care

  1. I fully agree. I myself believe in the wonders of natural medicine, but it is still best to ask the experts first before trusting anything that you see on the internet. If you’re worried that your doctor my not put your best interest in mind during a consultation then maybe you should consider looking for a more trustworthy one. In my case, the internet has made it possible for me to find my current <a href="http://www.arizonaretinalspecialists.com/blog/find-eye-specialist-arizona/&quot;. The criteria that I followed during selection are 1.) They should be in the ophthalmology for a long time 2.) They have an excellent track record. 3.) They should be accommodating during queries and is willing to answer eye-related question prior to check-up.
