Zinc cream alleviates cold sores
A randomized clinical trial on the treatment of oral herpes with topical zinc oxide/glycine.
Highly relevant to cold sore treatment
We conducted a double-blind, placebo-controlled clinical trial to explore the effectiveness of a zinc oxide/glycine cream in treating cold sores caused by facial and circumoral herpes. By dividing 46 participants into two groups, one receiving the zinc treatment and the other a placebo, we aimed to measure how this formulation affected the duration and severity of cold sore symptoms.

Our results were quite promising! Participants who began using the zinc oxide/glycine cream within the first 24 hours of noticing symptoms experienced cold sore lesions that lasted only an average of 5 days, compared to 6.5 days for those on the placebo. Additionally, we noticed a significant reduction in the overall severity of their symptoms, including blistering, soreness, itching, and tingling.

As for side effects, subjects treated with the zinc cream experienced only minor and reversible issues typical of ionic zinc salt solutions. This indicates that the zinc oxide/glycine cream is not only effective but also safe for treating cold sores, presenting a valuable option for many people seeking relief from this common condition.

Zinc gel aids cold sore healing
[Clinical double-blind trial of topical zinc sulfate for herpes labialis recidivans].
Strong evidence for zinc's effectiveness
We conducted a double-blind, placebo-controlled clinical trial to assess the impact of zinc sulfate gel on cold sores, specifically herpes labialis recidivans. In our study, patients treated with zinc sulfate gel, known as Virudermin Gel, experienced significantly reduced symptoms and faster healing compared to those who received just the gel without zinc.

The results were promising; the patients using the zinc gel reported less discomfort, and their sores healed more quickly. Importantly, this treatment showed no significant side effects, making it a safe option for managing cold sores. Additionally, the antiseptic properties of zinc sulfate helped prevent any superinfections, adding another layer of benefit to its use.

Overall, our exploration into zinc’s effectiveness provided valuable insights for both patients and healthcare providers seeking reliable cold sore treatment options. With simple application and proven results, zinc sulfate gel could become a go-to remedy for those frequently struggling with herpes labialis recidivans.

Zinc treatment helps cold sores
Recurrent herpes labialis: a pilot study of the efficacy of zinc therapy.
Directly addresses zinc's effect
We aimed to understand how zinc might affect the occurrence and duration of cold sores, also known as herpes labialis. In our study, we treated 20 patients, mostly women with an average age of 26.6, who experienced more than six episodes of cold sores each year. They received zinc sulphate at a dose of 22.5 mg twice daily during specific months over a year while we monitored their symptoms for 12 months.

Our results were promising. Patients reported a decrease in the frequency of cold sore episodes, averaging fewer than four instances per year. Moreover, the duration of these episodes was also shortened to around 5.7 days, significantly less than usual for these conditions.

Thus, we can say that systemic zinc sulphate seemed to effectively reduce both the number of cold sore outbreaks and the recovery time. This suggests that zinc might be a beneficial option for individuals who struggle with recurrent cold sores.

Improved skin condition
Beautiful!! Zinc is essential for skin, hair, and the immune system, especially for women during pregnancy and men for hormone production. I began taking zinc for my occasional rashes. While I didn't see results immediately, my skin became noticeably clearer and smoother by the end of the course, and I also avoided colds. Perhaps this is thanks to zinc!

Bitter taste problem
We always take zinc to prevent colds and during illness. This one is effective, but its bitter taste makes it hard to swallow; my eldest daughter felt nauseous and couldn't take it. I had to find another option. However, apart from this taste issue, I have no other complaints.

Zinc impacts cold sore recovery
Comparative analysis of salivary zinc level in recurrent herpes labialis.
Directly assesses zinc efficacy
We explored the connection between zinc levels and recurrent herpes labialis (RHL), commonly known as cold sores. In a study involving 80 individuals, we compared the salivary zinc levels of healthy people with those experiencing RHL during both the acute and convalescent phases.

The findings revealed that patients in the acute phase had significantly lower zinc levels (160.8 ng/ml) compared to when they were recovering (205.7 ng/ml). Both those phases showed lower zinc levels than the healthy individuals' average. This suggests that zinc levels are not just lower when cold sores are present, but also improve after the lesions heal.

Our results indicate that maintaining adequate zinc levels might be beneficial for people suffering from cold sores. Incorporating zinc supplements could play a role in both treating and preventing these uncomfortable outbreaks. We found that increasing serum zinc might help RHL patients, shedding light on a potential supportive treatment strategy for cold sores.

Zinc may relieve cold sores
Safety and effectiveness of an L-lysine, zinc, and herbal-based product on the treatment of facial and circumoral herpes.
Combination treatment relevance noted
We conducted a small pilot study to investigate how a combination of L-lysine, zinc, and herbal ingredients could help treat cold sores caused by the Herpes simplex virus. Our goal was to observe the changes in symptoms such as itching, burning, and soreness among participants over the course of treatment.

Thirty individuals, split evenly between genders, participated in our open-label study. We monitored their symptoms through various methods, including self-reported outcomes, photographs, and daily diaries. By the sixth day of treatment, most participants showed considerable improvement, with some experiencing full resolution of their symptoms.

While we didn't isolate the effect of zinc alone, its inclusion in the treatment mix seems promising. By the end of our study, we found that 87 percent of participants had improved symptomatically, which indicates that the combination treatment may effectively relieve cold sore symptoms. Importantly, no adverse effects were reported during the study, which adds to our understanding of these treatments' safety.

Pomegranate extract reduces inflammation
Anti-inflammatory activity of Punica granatum L. (Pomegranate) rind extracts applied topically to ex vivo skin.
Zinc's limited impact noted.
We examined how the combination of pomegranate rind extract (PRE) and zinc impacts cold sores, particularly focusing on inflammation. By applying these substances to ex vivo porcine skin, we were able to assess their ability to modulate COX-2, a key player in the inflammation process.

Our findings revealed that the topical application of PRE significantly reduced COX-2 levels in the skin after just six hours and maintained this effect for 24 hours. When we combined PRE with zinc, the results matched those of PRE alone, indicating that zinc didn't add extra benefits to inflammation control when used together.

However, we also noted that zinc alone showed no significant anti-inflammatory effect, highlighting that the benefits we observed were primarily due to the pomegranate extract rather than zinc. This suggests that while zinc is commonly thought beneficial for treating cold sores, its impact on inflammation might be limited unless paired with more potent anti-inflammatory agents like PRE.

In conclusion, pomegranates present a promising approach to managing inflammation and pain associated with cold sores, but zinc’s standalone effectiveness requires reconsideration.
