Hi Carole,
You can eliminate warts at the surface by sticking a thin slice of potato skin or duct tape over them, until they go. However, this probably won't prevent their recurrence, and for that, you will need to find the core issue.
According to Louise Hay's "Heal your body", warts stem from "expressions of hate", and "belief in ugliness", and also, "frustration". I hope you find something of relevance in these suggestions.
There is also an article on the emofree website, where the core issue causing the warts was fear of abandonment, and being alone. Hopefully you find it useful:

Good luck :-)
