Warts and your immune system

A wart is caused by a virus. The virus causes the top layer of the skin, called the epidermis, to grow rapidly. This growth is the wart.

Your immune system protects your body from infections and diseases by attacking anything it does not recognize.

However, your immune system works mostly in the dermis, the layer of skin below where the wart grows. It may take some time before it discovers the wart and attacks it.Anatomy of the skin

What is candida?

Candida is a yeast. We inject this yeast into the dermis layer of the skin and all around the wart.

Your body does not recognize the injected yeast and activates the immune system in the area to attack it. The immune system will also attack the wart.

What to expect during the injection

  • Treatment is quick.
  • No special care needed.
  • No scarring or open sore.
  • You can go back to normal activities including swimming, sports, etc.

After the yeast injection

  • You will have a red bump in the area, similar to a mosquito bite.
  • The skin will turn red in a few days.
  • The warts will slowly start turning somewhat black and the crust will fall off.

Note: Time varies depending on size of wart.
