Context: L-lysine, an essential amino acid, inhibits normal replication of Herpes simplex virus (HSV), shortening the normal course and duration of the disease. This study was conducted to determine the effectiveness of a combination of L-lysine with botanicals and other nutrients in relieving the symptoms of facial and circumoral herpes.
Methods: This small pilot study was conducted using an outcome (open-label) model. Thirty male and female participants (15 in each group) meeting the inclusion/exclusion criteria were admitted to the study. The 10 outcome measures used to monitor the sores were tingling, itching, burning, tenderness, prickling, soreness, bump/swelling, small blister(s), oozing blister(s), and crusting, as well as before-and-after photographs of the lesion, and a daily diary.
Results: At the end of treatment the ointment produced full resolution in 40 percent of the participants by the third day and in 87 percent by the end of the sixth day. A cold sore episode may last up to 21 days without treatment.
Conclusions: Overall data indicated significant improvement in participants by the sixth day of treatment for all but two participants. There were no adverse effects reported during this study.
