Therapeutic Effect of Melissa Gel and 5% Acyclovir Cream in Recurrent Herpes labialis: A Double-Blind Randomized Clinical Trial

Evaluating the effectiveness of topical olive leaf extract emulgel in managing recurrent herpes labialis: a randomized controlled clinical study

Recurrent herpes labialis (RHL) is a lifelong oral health issue that affects about one-third of the world's population, causing frequent, painful, and discomfort lesions. This randomized, triple-blinded study aimed to evaluate the effectiveness of olive leaf extract (OLE) compared to acyclovir cream (Veramid 5%) in managing vesicular stage of RHL lesions. Forty patients were randomly divided into two equal groups and were instructed to apply the prescribed medication five times a day for five consecutive days. The evaluation was carried out by measuring the pain intensity on the first day before the treatment was applied (T0), 48 h (T1), and 7 days later (T2). Additionally, the day when the pain completely healed and the day when the lesion's crust fell off spontaneously were recorded. Statistical analysis was conducted using the Mann-Whitney test at a significance level of α = 0.05. The study results indicated that there were no significant differences in pain intensity between the two groups during the three evaluation times: T0 (P = 920), T1 (P = 0.596), and T2 (P = 1.00). Furthermore, there was no significant difference in the day when the pain was completely healed (P = 0.697). However, the OLE showed a statistically significant advantage regarding the day the lesions' crust fell off (P = 0.040). In conclusion, OLE may be a potential alternative treatment for RHL.Trial registration: isrctn.com ID: ISRCTN87606522, 04/09/2023.

Antiviral Potential of Melissa officinalis L.: A Literature Review

The use of synthetic drugs has increased in recent years; however, herbal medicine is yet more trusted among a huge population worldwide; This could be due to minimal side effects, affordable prices, and traditional beliefs. Lemongrass (Melissa officinalis) has been widely used for reducing stress and anxiety, increasing appetite and sleep, reducing pain, healing wounds, and treating poisonous insect bites and bee stings for a long time. Today, research has shown that this plant can also fight viruses including Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), Herpes Simplex Virus (HSV), and Human Immunodeficiency Virus (HIV) through various mechanisms such as inhibiting HSV-1 from binding to host cell, inhibiting HSV-1 replication during the post-adsorption or inhibiting main protease and spike protein of SARS-CoV-2, furthermore, be effective in treating related diseases. This Review investigated the antiviral properties of Melissa officinalis and its effect on viral diseases. More in vitro and in vivo studies are needed to determine Melissa officinaliss underlying mechanism, and more randomized controlled trials should be done to identify its effect in humans. Also, due to the usefulness and lack of side effects, it can be used more as a complementary medicine.

The efficacy of olive leaf extract on healing herpes simplex virus labialis: A randomized double-blind study

OBJECTIVE

Herpes simplex virus (HSV), as a common infection in healthy individuals, is treated symptomatically, but drug resistance and the side effects of drugs have drawn the attention of researchers to complementary medicine. Olive Leaf Extract (OLE) has antiviral effects that may treat HSV. The current study aimed to compare the clinical effects of OLE and Acyclovir on HSV-1.

METHODS

This randomized double-blind clinical trial was conducted on 66 patients who had already been diagnosed with HSV-1. The participants were randomized into two groups, receiving 2% OLE cream or 5% acyclovir cream five times a day for six days. The symptoms were evaluated before, and three and six days after the interventions. Data were analyzed using the SPSS software through the Kolmogorov-Smirnov test, chi-squared, t-test, and repeated measures ANOVA.

RESULTS

The results showed clinical symptoms decreased in both groups during the study and both medications were effective in the treatment of HSV-1. However, the OLE group experienced less bleeding (P = 0.038), itching (P = 0.002), and pain (P = 0.001) on the third day as well as less irritation (P = 0.012), itching (P = 0.003) and color change (P = 0.001) on the sixth day compared to the acyclovir group. The treatment course for participants in the OLE group was shorter than in the acyclovir group (P = 0.001).

CONCLUSION

The evidence from these trials suggests the OLE cream is superior in the healing of episodes of HSV-1 over the acyclovir cream. Future studies are recommended to investigate if OLE could be an adjunct to acyclovir treatment.

Bee products and the treatment of blister-like lesions around the mouth, skin and genitalia caused by herpes viruses-A systematic review

OBJECTIVES

To assess the value of bee products with respect to antiviral efficacy against herpes viruses.

DESIGN

A systematic review was done using the JUSTfind System of the Justus-Liebig-University Gießen and Scopus.

RESULTS

Three trials on honey and 6 trials on propolis were conducted. Each trial provided evidence that these two bee products are interesting alternatives to acyclovir, especially propolis, which was found to be superior to acyclovir in 4 trials.

CONCLUSIONS

The evidence from these trials suggests that propolis is the best of all natural possibilities in the treatment of herpetic skin lesions, especially those related to HSV-1. Future studies should analyse if propolis could be an adjunct to treatment with acyclovir. For lesions in the oral cavity, honey could be an interesting alternative.
