According to the Environmental Protection Agency （EPA） and the World Health Organization （WHO）, air pollution affects millions of people worldwide. Hundreds of thousands of deaths each year and a range of diseases, particularly among vulnerable groups （i.e., children, the elderly, and people with special medical conditions）, are attributed to air pollution. These effects are not always caused by single pollutant in the air; rather, they are considered consequences of the multi-pollutants to which people are simultaneously exposed.展开更多

The trial was designed as a double-blind, randomized dermatological study in 150 outpatients with Herpes labialis. The primary parameter was the duration in days until painless incrustation in 50% or 90% of the patients (observable in 121 patients). Secondary parameters were local pain (assessed on a visual analogue scale), itching, burning and tension/ swelling on a verbal rating scale, and tolerability. Visits were performed on days 2/3, 5/6 and 8/9. Best efficacy results with shortest healing time (3.4 and 5.4 days in the 50th and 90th percentile, respectively;p = 0.008 vs. 1% and 0.09 vs. 0.1%) and good tolerability were observed with the 0.5% concentration. All three concentrations achieved highly significant therapeutic results in comparison with baseline values (p < 0.0005) for all secondary parameters as early as day 2/3. Analgesia was the most prominent effect for the patients. Conclusion: The 0.5 % concentration of propolis special extract GH 2002 in a lip balm was found to have the best risk-benefit ratio for the treatment of Herpes labialis.展开更多
