A named tincture was found fit for beverage use
On this page12
The sentence
"Alcohol (including dehydrated alcohol and dehydrated alcohol injection), U.S.P.; alcohol and dextrose injection, U.S.P.; and tincture of ginger, H.P.U.S., have been found to be fit for beverage use and are disapproved for drawback."
Three preparations named
Two forms of alcohol and one tincture. All three sit in official pharmacopoeias and all three were found fit for beverage use.
The section it sits in is the generous one
It deals with pharmacopoeia preparations, which are generally approved. This paragraph is the list of exceptions, which is what makes it informative.
So being official is not the test
A preparation can be in the United States Pharmacopeia or the Homeopathic Pharmacopoeia and still be fit for beverage use. The monograph does not settle it.
And being called a tincture is not the test either
Which is the point for this group. Tincture is a method of preparation, an alcohol extract, and the name carries no finding with it.
Ginger is the instructive one
A warming, palatable, aromatic extract. It reads as a drink because it is one, and the regulation says so in as many words.
Which suggests what the test is actually about
Palatability and the practical possibility of drinking the thing, rather than its category, its monograph or its container.
And nothing in this group is assessed here
Whether a CBD, CBN or THC tincture is in scope at all, and what a formula examination would find, is not something a container catalog establishes.
The useful transfer is the shape of the error
Assuming a classification follows from a name. The reloading property makes the same point about an exemption and the adjacent botanicals property about a listed ingredient category.
Two of the three are not tinctures at all
Alcohol U.S.P. and alcohol and dextrose injection are not extracts, which makes the inclusion of ginger among them the deliberate part of the list.
Read the exception list, not just the rule
The general approval is the headline and the three named disapprovals are where the standard shows its teeth.
