Fever Blister
Manuka (Leptospermum scoparium), Ravensara (Ravensara aromatica) and Melissa (Melissa officinalis) with 10% food-grade Emu oil

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.

1. I have used a myriad of different natural remedies for fever blisters over the years, but Linda's Fever Blister 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 Fever Blister 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 Fever Blister blend and it nips it in the bud. - Sarah

5. My dad tried my Fever Blister 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 Fever Blister 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 Fever Blister blend, and in less than 24 hours, it was healed! - Carol

7. I recently diffused the Fever Blister 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 Fever Blister. 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

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. Flushing with water will only send the essential oil back to the eye's membranes. 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. We’ve not known this to cause permanent injury or long-term discomfort, but if you feel concerned, please call your health care provider.
