Does inherent moisture accompanying an ailment invalidate ablution?

Primary text

Inherent moisture that remains attached to the ailing area does not invalidate ablution because it is inseparable from the moisture itself. If this inseparable moisture were to invalidate ablution, its mere presence would necessitate invalidation under all circumstances. Furthermore, since this substance does not separate from the source, it does not invalidate the state of purity, similar to other constituent parts of the body.
