Primary Remedies

Calendula Ointment

This remedy keeps the skin or lips moisturized and speeds up healing.

Natrum muriaticum

This remedy sometimes stops a herpes outbreak if taken in the early, tingling stage. It is also helpful for raw, red cold sores that develop on the lips and corners of the mouth, as well as the nostril area, face, and chin. Eruptions may also appear in the genital area. Eating too much salt (which the person craves) and being in the sun sometimes aggravates the symptoms.
