(Diluted.) Sulphuric acid mixed with 11 times its bulk of water. Used in dyspepsia, also to check sweatings, salivation and diarrhea; also as a gargle.

So what happens if I make it?

A one-in-eleven dilution is still a strong acid, and the recommendation to gargle with it puts it in prolonged contact with the mouth and throat. Enamel does not recover.

This is the same substance as the summer beer elsewhere on this site, presented straight, without the orange syrup. The cookbook is carrying a pharmacopoeia in its back pages.

Notes from the 21st century

  • Dilute sulphuric acid was official. It appears in period pharmacopoeias as an astringent. The preparations were made to a standard the home reader could not verify.
  • Dyspepsia meant indigestion. The reasoning was that a sour stomach needed more acid, not less — the opposite of how it is treated now.
  • Nothing on a shelf today matches it. Sulphuric acid sold now is drain cleaner or battery acid, and neither is made to any ingestible standard.
