Can orange oil be used for Candida albicans? The answer is: certainly. When you develop your treatment plan, you may wish to combine several different essential oils to achieve maximum results. Dr. James Duke, in his book The Green Pharmacy, mentioned that herbs often can be mixed to create a synergistic effect. This philosophy should also hold true for the essential oils that are fungicidal. Some oils may lack important chemical constituents that are present in other oils. By combining oils together, you should be able to create a more efficacious yeast infection cure. You can find other essential oils that are good for treating a yeast infection on this page of this website: essential oils for yeast infection.
One study, published in FEMS Yeast Research [Volume 5, Issue 9, pages 867–873, June 2005], tested the effects of 38 different plant essential oils on four different isolates of Candida albicans (this yeast is the most common species that attacks the vagina and causes yeast vaginitis). Many of the essential oils showed some degree of efficacy as a candicidal natural remedy. However, one of the top performers among these 38 oils was essential orange oil. The best performer among the 38 oils tested was lemongrass essential oil.
It is possible there are two other essential oils which are even superior to lemongrass, and these are thyme (Thymus vulgaris) and oregano (Origanum sp.). One study, published in Pharmaceutisch Weekblad [1986, Volume 8, Issue 6, pp 289-292], also analyzed an array of plant oils; 53 oils to be exact. Unfortunately, only one strain of Candida albicans was analyzed; other pathogens were also analyzed aside from this strain of Candida. Additionally, lemongrass oil was not one of the 53 oils tested either. Both thyme and oregano essential oil performed markedly better at controlling the test strain of Candida albicans than any of the other oils.

A vital study to check out, to get an idea of how to use essential orange oil, is one published in the Journal of Pharmacy Research [2010, 3(2), p.414-416]. This study, interestingly enough, showed that undiluted orange oil could in fact kill Candida albicans. However, a diluted orange oil (1 to 3 ratio) had absolutely no effect on the fungus. Consequently, if you try diluting orange oil before you use it in the vagina, it may have no effect at all. The only way to be more confident this oil will treat a yeast infection is if you do not dilute it. It would be prudent to consult a professional herbalist or knowledgeable medical professional before you use large amounts of undiluted orange oil in the vagina. If you have a skin yeast infection, it is much safer to use this oil topically on your skin than it is inside your vagina.
The other strains of bacteria tested in this study, also show (somewhat ancillary to this discussion) a definition of orange oil’s antibacterial capabilities. None of the 3 bacteria (one of which being Escherichia coli) were inhibited by even undiluted orange oil. Thus, overall, orange oil is a less efficacious candida killer and perhaps a very poor antibacterial agent. Be warned, I’ve seen others say online that orange oil is a good antibacterial, but actual research suggests it is not so great.
This study also used other essential oils, and one showed remarkably strong anti yeast activity; that oil was cinnamon oil. Even diluted at a 1 to 3 ratio, cinnamon oil was a very strong Candicidal. You would probably be better able to halt a yeast infection by using cinnamon oil. Additionally, cinnamon oil was also a capable antibacterial; as shown by this study.
