Prunella Vulgaris can be found on any path and in the grass of any garden. The plants in this balm come from the fields in my back yard overlooking the Cantabric Ocean. It goes by the popular name Self Heal and Heal All, and this says it all. If you would like to know in detail how it can help with your lips' cold sores please read this article in my blog:

Please note that due to post-weighing issues you will receive an aluminium tin rather than the heavier glass jar in the photos.
