In a recent study, the researchers found that when patients took herbal medicine and used the skin on their chest to help relieve the symptoms of a cold, the skin was able to prevent the infection from forming.
In addition, when the patients took cold medicine and rubbed their cheeks, they also used the area to get rid of the itchiness they felt.
But when they took herbal remedies and rubbed the face, they did not feel the itching at all.
The findings may be due to the fact that herbal medicines are not known to have anti-inflammatory properties, which are associated with a lower risk of developing a cold sore.
“It seems to be an effective remedy, as there is no significant reduction in the rate of cold sore development in this group of patients,” Professor Kim said.
However, the study was small and was not able to investigate the effect of different herbs or the use of different types of skin.
