Historical Definition

Porosa is St John’s wort.

Meaning

The identification supplies an English plant name without a preparation or therapeutic purpose.

Use in the Book

Relloleum uses St John’s wort to distinguish a virtue associated with heat from another accidental and hidden virtue. That fuller discussion belongs to the corresponding conceptual entry, while Porosa supplies the short lexical identification.

Places to Read

Relloleum. A distinction between a manifest quality and an occult virtue.

Vegetabilia. Growing things described through rootedness and branching.
