American Elixir of Calisaya 8 fluid ounces Orange Syrup 24 fluid ounces
This is a two-line fountain formula from an era when the soda counter sat at the front of a drugstore and the syrup jars held pharmacy stock. The problem is not the technique but the first ingredient.
- What Elixir of Calisaya wasA formulary preparation made from the bark of Cinchona calisaya — the quinine tree — extracted into sweetened alcohol, usually with aromatics. It was dispensed as a bitter tonic, whether compounded by the chemist or bought ready-made, and it is not a food ingredient in any modern sense.
- The active constituent is a drugCinchona bark carries quinine and related alkaloids. Quinine is regulated as a pharmaceutical and is capped by law at low levels in beverages; it can cause thrombocytopenia, haemolysis, hearing loss and cardiac arrhythmia, and some of these reactions are idiosyncratic, occurring at doses others tolerate. A bark extract at pharmacy strength gives no way to know how much alkaloid is in a glass.
- No dose control anywhere in the formulaEight ounces of elixir into twenty-four of orange syrup gives a one-in-four dilution, but the alkaloid content of the elixir itself varied with the bark and the batch, and the recipe says nothing about the size of a serving. Nothing in the chain is measured against a safe intake.
- Substitution does not rescue itModern tonic water is quinine-flavoured within a legal ceiling and is a different product entirely; homemade cinchona bark tinctures sold for cocktail use carry the same uncontrolled-dose objection. If you want a bitter orange fountain syrup, use a current recipe built on gentian, quassia or bitter orange peel.
- Reading the unitsFluid ounces here are US measure — 8 fl oz is a cup, 24 fl oz three cups — so the batch was a quart of finished syrup, enough for roughly thirty single-ounce servings.
Cinchona bark reached Europe from Peru in the seventeenth century and by the nineteenth was the standard remedy for intermittent fevers; calisaya, the yellow bark of Cinchona calisaya, was prized as the richest source of quinine, and "Elixir of Calisaya" appears in American dispensatories as a sweetened, alcoholic bitter tonic prescribed for poor appetite and general debility. Its presence in a soda fountain manual is a reminder that the fountain grew out of the pharmacy: the same counter that mixed prescriptions also sold flavoured carbonated drinks, and tonic, celery, coca, kola and pepsin syrups moved back and forth between the two trades without much sense of a boundary. Adding orange syrup here follows a familiar logic of making a medicinal bitter palatable to a walk-in customer — much the same logic at work in tonic water, commercially established from the mid-nineteenth century, where quinine survives as a flavour long after it stopped being the point.
