Contender (formerly called Fever Blister)
Manuka (Leptospermum scoparium), Ravensara (Ravensara aromatica), Melissa (Melissa officinalis)

*This blend was formally known as Fever Blister. Emu oil was added as a therapeutic component, but this blend is now essential oils only. To duplicate the former Fever Blister blend, add 1 part Emu oil to 14 parts Contender. Then add the additional carrier oil of your choice.  (See Testimonies #11, #12 and #13.)

Manuka is similar to Tea Tree oil, but is much less medicinal in aroma. It is also thought that Manuka is more effective than Tea Tree against gram positive bacteria.

Children? Use with caution on children under 2 due to Melissa.
Pregnancy/Breastfeeding? Avoid oral use during pregnancy or lactation, due to Melissa.
Medication Incompatibility Oral use: Acetaminophen, Antidepressants CYP2B6 substrates, Diabetes, Ephedrine

1. I have used a myriad of different natural remedies for fever blisters over the years, but Linda's Contender is the best thing I've ever tried. I've very happy with this blend and am telling my friends! Thanks, - F.M.S.

2. This blend works like nothing else for fever blisters! - Sarah

3. Since I was very young I'd get fever blisters and it seemed like a long process: first the tingle and itch, then the painful throbbing blister that lasted days, and then the drying up and scab that lasted several more days until it finally went away. With the more recent fever blister I got, I felt the itch in the morning, and by evening it had formed a large blister. I started applying your Contender blend on it that first day, so then that night when it formed the blister, I applied it again every time I thought about it. By the next morning, it was already to the drying stage and had completely disappeared in just a few more days. So a process that normally took my body 2-3 weeks to complete was done in a week. I think I could have sped the process up it I'd started applying the blend at the first sign of the itch instead of midday, and if I'd kept applying it after it began to dry up. - Sherri

4. My young daughter gets a lot of fever blisters, and when I see one coming on, I apply the Contender blend and it nips it in the bud. - Sarah

5. My dad tried my Contender blend and he was sold. He said it was the best thing he ever used for his fever blisters, so he asked me to order some for him. - Elizabeth

6. I just have to thank you so much for the Contender blend! I never get sores on my lips but had one recently that was dry and very stubbornly refused to go away. I bought your Contender blend, and in less than 24 hours, it was healed! - Carol

7. I recently diffused the Contender oil over night and it shut the blister down. The next day, I couldn't even see it anymore. - Joleen

8. I have been using Contender. I start applying it at the first sign of a fever blister, and they have not developed. I'm sure it just stopped them. I am very prone to them and so far so good with it. - Diane
9. Wow! I've tried over-the-counter products and other oils (including the more expensive Melissa) for my cold sores and nothing has come close to the success I had with Contender! I began applying it a few times a day at the first tingle, and a true cold sore never even developed! None of the "blister" stage, no scab, no pain! Thank you for this amazing oil! - Diane
10. Thanks for your Contender Blend; it works great when I catch one early. When they start without my awareness, it takes longer (sigh). Hopefully I'll never develop a sensitivity to this blend. It works best of anything I've tried since I started it 6-8 months ago. - Wendy
11. I use your Contender blend ever so often and have had great success, as do others in my family. I just recently purchased a new bottle and lo and behold a blister started to form. I applied immediately, but this time no results. It continued into 2 huge ones. Has anything changed or can I become immune? - Lynda S.
[HEO's Response: I’m so sorry it didn’t work for you this time. The blend formerly had Emu oil in it (1mL in a 15mL bottle), and now it is just the essential oils so that the user can add the carrier oil of their choice. That’s the only change to the formula. It is a very good anti-viral blend and can help us “contend” with many health issues, so I'd expect it to work. Did you use a carrier? By using a carrier, we help the oils to better absorb and avoid any risk of skin irritation.
Lynda's Response: She did not use Emu as a carrier and will try that the next time and let us know the results.]
12. I love this blend, and I feel that the Emu is a key component. Emu has a richer feel to it than coconut oil and has its own anti-inflammatory properties. It helps the blend to soak in and is soothing to the lips. - Janine
13. I had two 'eruptions' just before going on a 3-week trip. I had a 2mL sample size of Contender, so I put a drop on each (undiluted). Nothing changed. I reapplied several times with no notable change. I'd read the testimonies about adding Emu, so I added Emu to dilute the blend to the suggested 24% ratio. After one application, both eruptions responded. The inflammation quickly reduced, and I reapplied several more times through the day. By the next morning, they were gone. There was not a sign of either one! In my opinion/experience, Emu is a necessary component for a fever blister. - Linda

Melissa contains Citral, which is a strong sensitizer. Suggested dilution for topical use is 6 drops per fluid ounce (0.7%). Avoid use on hypersensitive or damaged skin. Not typically used topically on children under age 2.
*Robert Tisserand reported at a Clinical Safety Aromatherapy conference (2013) that there is a possibility that Citral (in Lemongrass) may affect tooth and bone development in the fetus. "Citral impairs reproductive performance in female rats by reducing the number of ovarian follicles (Toaff et al 1979). The effect, however, was seen only after a series of six monthly ip injections at a dose of 300 mg/kg. This is equivalent to injecting ~ 25mL of lemongrass oil into a woman's abdomen. Based on other research, we have restricted citral exposure in pregnancy" (Tisserand, Robert; Young, Rodney, Essential Oil Safety: A Guide for Health Care Professionals, Elsevier Health Sciences UK 2nd Edition 2014, pages 149.). 
Avoid contact with the eyes and other sensitive areas. Essential oils are both lipophilic and hydrophobic. Lipophilic means they are attracted to fat— like the membranes of your eyes and skin. They are also hydrophobic, meaning they do not like water. Applying a carrier oil will create another fat for the essential oil to be attracted to other than the membranes of the eyes or skin. Tisserand suggests: "With essential oils, fatty oil has been suggested as an appropriate first aid treatment, though the advantage of saline [eyewash] is that the eyes can be continually flushed, and this is less easy with fatty oil.” We are not aware of a case where essential oil in the eyes caused permanent injury or long-term discomfort, but if you feel concerned, please call your health care provider.
