Most Useful Review
I have been using Olive Leaf Extract for over a year, initially recommended by my naturopathic doctor for treating cold sores. I travel to India for mission trips and did not get sick during my recent five-week trip. I take one tablet in the morning and one at night. I also use it at the first sign of a cold, which subsides within a couple of days. Since taking Olive Leaf, I haven't had flu symptoms for a year, despite not receiving a flu jab.

Curcumin and blue light therapy
Photodynamic Therapy Mediated by Curcumin and Blue Light for Recurrent Herpes Labialis: A Case Report.
Most Relevant Research
We explored the effectiveness of photodynamic therapy (PDT) using curcumin and blue light for treating recurrent cold sores, specifically herpes labialis. This innovative treatment approach was assessed based on its ability to accelerate the healing of lesions and reduce their recurrence.
Our findings suggest that PDT shows promise as a safe and cost-effective option for managing this troublesome condition. However, it is important to note that the study was primarily focused on the combined effect of curcumin with PDT, making it difficult to determine the isolated benefits of curcumin on its own for cold sore treatment.
Overall, our research highlights an exciting potential pathway for alleviating the symptoms associated with recurring herpes labialis, paving the way for future studies to further investigate its components and their individual effects.

Partial clearing achieved
Most Useful Review
After using this probiotic for a month, my allergic child experienced partial clearing of her atopic dermatitis, as long as allergens were avoided.

Zinc and cold sore recovery
Comparative study of serum zinc concentration in recurrent herpes labialis patients and healthy individuals.
Most Relevant Research
We explored the relationship between zinc levels and recurrent herpes labialis (cold sores) through a study involving 43 patients with a history of this condition and 42 healthy individuals. By measuring serum zinc levels using a colorimetric method, we aimed to find out whether these levels differ significantly between both groups and how they relate to the severity and duration of cold sore episodes.
Although we found that serum zinc levels did not significantly differ between the patients and healthy subjects, we observed an interesting correlation regarding recovery times. Specifically, lower serum zinc levels appeared to be linked to longer recovery periods from cold sores. This suggests that zinc might play a role in speeding up recovery, though it was not a significant factor influencing relapse frequency or patient demographics such as age and sex.
Overall, while the study didn’t establish a direct benefit of zinc supplementation, the findings indicate that zinc deficiency might contribute to longer-lasting cold sores. Therefore, we suggest that evaluating zinc levels in patients experiencing recurrent cold sores could be beneficial and that zinc supplementation may be worth considering in treatment protocols.

Vitamin C shows potential for cold sores
A clinical pilot study of lignin--ascorbic acid combination treatment of herpes simplex virus.
Most Relevant Research
We conducted a clinical pilot study to evaluate the effects of a combination treatment of lignin—a substance derived from pine cones—mixed with vitamin C on cold sores caused by the herpes simplex virus type 1 (HSV-1). Our study included 48 healthy participants, ranging from 4 to 61 years old, who had active lesions of HSV-1.
Participants received a daily dose of the lignin-ascorbic acid treatment for one month. Notably, those who began the treatment within the first 48 hours after the onset of symptoms did not develop typical cold sore lesions. For others who started later, we observed a shorter duration of cold sores and less severe symptoms compared to their previous outbreaks.
Many participants reported a reduction in both the severity and frequency of their cold sore episodes during treatment. Although the results suggest some benefits of this combination treatment, it’s important to note that vitamin C was part of the blend, making it challenging to evaluate its individual effect on cold sores directly.
Thus, while the combination of lignin and vitamin C appears promising for preventing and treating HSV-1 infection, further studies isolating vitamin C's effects would be helpful to understand its specific role in managing cold sores.

Iron therapy reduces cold sore frequency
Response to replacement iron therapy in sideropenic individuals with recrudescent herpes labialis.
Most Relevant Research
We investigated how iron replacement therapy affects the occurrence of cold sores, also known as recurrent herpes labialis, in people with low iron levels, a condition known as sideropenia. In our study, ten patients with confirmed sideropenia and a history of cold sores took ferrous sulphate for three months.
Before starting the treatment, these individuals reported experiencing an average of 0.78 episodes of cold sores each month. After the iron therapy, this number significantly dropped to just 0.2 episodes monthly. Furthermore, we found that there was a noteworthy increase in serum ferritin levels, a marker indicative of iron status, after treatment.
The results suggest that iron therapy may play a significant role in reducing the frequency of cold sores for those affected by iron deficiency. These findings are intriguing and warrant further exploration into iron supplementation as a potential option for managing cold sores in individuals with low iron levels.

I administered this iron supplement with my daughter, and after four months, her ferritin rose from 7.5 to 34, which stabilised. Initially, she experienced intestinal issues, but after adjusting the dosage, everything was fine, and iron levels normalised. Previously, low ferritin resulted in frequent colds. Hemoglobin was 135, so I find this drug very effective!
