Meaning
Oil of salt is a historical preparation-name whose exact modern chemical identity is not established by this passage. Corrosive names the objection raised against such medicines. The author grants danger under specified conditions but disputes the opponents' general conclusion; that historical dispute is not evidence of safety.
Use in the book
III.18 contrasts ordinary relief with the deeper efficacy claimed for spagyric preparation. The author cites the learned Pena's use of oat roots for stones and argues that extracting the root's effective principle would give a complete cure. A simple here is the individual medicinal material, not a weak or uncomplicated remedy.
Salt is then said both to harden stones and, as oil of salt, dissolve them. The argument does not simply repeat “like cures like.” It says the two substances are alike by name or origin while their effects differ, so contrary effects can oppose one another. A comparison of greater heat dispersing lesser heat reinforces that logic. The burn practice used for the comparison is unsafe and is recorded only as the author's historical analogy, not as a treatment to follow.
The imagined critics call the preparations corrosive and therefore harmful to take internally. Nuysement says he would concede the objection if they were taken alone and in excessive quantity, while those skilled in giving and receiving them reject the critics' conclusion. The qualifications belong to the text and must remain visible, but they supply neither an actual safe dose nor a demonstrated safe preparation. The passage provides no warrant to identify the oil confidently as a particular acid, ingest corrosives or apply further heat to burns.

Translation
The English retains “taken alone and in excessive quantity” rather than omitting the concession. Note 277 leaves oil of salt unidentified because preparation detail is insufficient, and note 276 distinguishes the historical claims from present-day medical advice. These observations protect both fidelity to the dispute and the reader's understanding of its evidential limits.
