I have a widespread plantar wart on left foot that spread to right foot a little bit. been there for over ten years and nothing takes it away or treats it. i was told by a dermatologist that zinc will help, but it will never go away. is this true?

When taken orally...: Oral zinc sulphate tablets at a dose of 10 mg kg(-1) daily seems to be an effective therapeutic option for stubborn warts and proved to be safe with few adverse effects. Ask a doctor who is familiar with this treatment for more details.

Salinocaine : For many years I used Salinocain and retin A cream covered with a waterproof dressing for 3 days. And see the pt weekly. The idea is to try to stimulate the immune system to attack the Verruca This can take weeks or months but eventually it will work. Not a bad practice builder.
