The material components for this spell vary with the type of corruption. For example, garlic is used for a vampirism corruption, a sprig of wolfsbane is used for a lycanthropy corruption, and so on. The GM can determine appropriate material components, but the components should cost at least 25 gp.
It doesn't say that you litterally need 25 gp-worth of garlic or wolfsbane, just that the total cost is about 25 gp. I'm sure the bulk of the cost is meant to consist of fancy oils and whatnot.
