Thrush is candida. All candida can be killed using the Candida Zapper. Why not just use candida medicine or natural remedies? Because they don't work. When candida is chemically threatened then it transforms to a protected spore form or roots deeper into the body. I know because I had it most of my life and tried everything. The Candida Zapper by BioElectric produces a high frequency microcurrent output that candida can't run from.
