Antique 1920s-40s Tasteless Castor Oil Label 🧪 Rare, Have to read!

How Do You Not Taste Castor Oil? 🧴 "Tasteless" Castor Oil — and the Very Precise Instructions for Not Tasting It

Size: 2 3/4" x 1 1/4"

This is an original, unused chemist's label for Tasteless Castor Oil, issued by C. Charnley, Pharmacist, of Wilmslow in Cheshire, England. Black type on cream stock, 2 3/4 by 1 1/4 inches, never applied to a bottle. Here is everything printed on it:

TASTELESS CASTOR OIL
DOSE.—Half an ounce to one ounce and a half, floating on warm milk, coffee, or on water, and covered with a small quantity of spirit.
C. CHARNLEY, Pharmacist, WILMSLOW

Plus a four-figure telephone number. No address, no printer's mark, no date, no company name.

🥄 Read That Dose Line Again — It Is a Physics Trick

If the oil is tasteless, why does it need floating on something and covering with spirit? Because it is not tasteless, and everybody involved knew it. What that instruction describes is a three-layer float, built in the glass to keep the oil off your tongue entirely.

Castor oil is lighter than water or milk, so it floats on top of them. Spirit is lighter than castor oil, so it floats on top of that. Follow the instruction exactly and you get milk at the bottom, a layer of oil suspended in the middle, and a thin cap of spirit on the surface. You swallow through the spirit, the oil goes past in the middle without ever touching your tongue, and the milk follows it down. Dispensing chemists ran a more exacting version of the same trick, calculating the relative densities so the dose hung in the glass as a sphere.

That is the whole game. "Tasteless" was the marketing; the dose line is the workaround that made the claim survive contact with an actual patient. The trade chased a genuinely tasteless castor oil for decades — formulas from the period reach for saccharin, vanillin, cinnamon and anise oils — and never really got there.

💊 What Castor Oil Actually Was

Castor oil comes from the seed of Ricinus communis, and it is one of the oldest medicines we have any record of. It appears in the Ebers Papyrus around 1550 BC, and castor seeds have been recovered from Egyptian tombs. The British Pharmaceutical Codex of 1911 calls it "a mild purgative" and "the most valuable laxative available in medicine," setting the dose at four to thirty mils and noting it is best given in milk — which is exactly what this label says.

Worth noticing: this label's dose runs up to an ounce and a half, which is above the Codex maximum.

🏛️ C. Charnley, and the Word "Pharmacist"

That word on the label is a credential, not a job description. The Pharmacy Act of 1868 made it an offense to call yourself a chemist, a druggist, a pharmacist or a dispensing chemist in Britain without being on the register. Printing it was a legal statement about his standing.

And Charnley is unusually well documented for a village chemist. The Wellcome Collection holds two volumes from the Charnley shop, MSS.8437–8438. One is a pharmacy recipe book running 1866 to 1940, inscribed on its first page "Charles Charnley, 16 May 1866" — medical, household, cosmetic and culinary preparations, a few veterinary and horticultural ones, written in several hands with periodical cuttings pasted in. The other is a clothbound volume of 1869 to 1925 whose opening pages are a register of prescriptions dispensed to named individuals. A working chemist's shop, on paper, across three generations of handwriting. The C. Charnley on this label may be the man who signed that first page in 1866, or the one who came after him.

"Charnley C." shows up in the Cheshire trade directories on Grove Street in Wilmslow through the later nineteenth century and into the twentieth, and the shop was still trading under the Grove Pharmacy name in the late 1930s — a notice in the Stockport Advertiser of 22 July 1938 names C. Charnley at The Grove Pharmacy, Wilmslow. There is a nice cross-check buried in the directories too: one edition marks him with the symbol for a dealer in photographic materials and apparatus, which lines up neatly with the photographic recipes sitting in the shop's recipe book at the Wellcome.

🕰️ Which Came First — What This Label Tells You That the Others Do Not

This is the detail I like best, and it comes from comparing two of his labels rather than from any archive.

This one trades as "C. CHARNLEY, Pharmacist" — a man, personally. His Glycerin of Thymol label trades as "CHARLES CHARNLEY LTD., The Grove Pharmacy" — an incorporated company with a registered address. Both carry the same telephone number, 3059 - which the shop kept from the 1940s into the 1960s, so the number alone doesn't say which came first. The name does: a business does not un-incorporate: this castor oil label is the earlier of the two, printed while Charnley was still trading in his own name, before the Ltd went up over the door. The plainer printing says the same thing — one ink, simple rules, no ornament, against the sage-and-navy of the later sheet.

The Wilmslow paper lets me put years on it. The shop's number was 4X around 1909 to 1913 and 59 from 1914 into at least 1924. By September 1946 the ads read "Charles Charnley, Pharmacist, Tel. 3059," almost word for word this label, and by May 1949 it was Charles Charnley Ltd. So this castor oil label comes from the 3059 years before the Ltd: somewhere between the mid-1920s and the late 1940s, and not the 1910s.

The Wilmslow paper fills in the rest of the story. Charles Charnley was advertising as a dispensing chemist on Grove Street by 1875, the shop's phone number was 4X around 1909 and 59 by 1914, and by 1946 it was "Charles Charnley, Pharmacist," at Wilmslow 3059. Sometime between 1946 and 1949 the business became Charles Charnley Ltd, and in time it added a second shop at 20 London Road in Alderley Edge. In 1998 the paper called it Wilmslow's oldest chemist shop and talked to 87-year-old Charles Charnley, whose ancestors, it said, founded the business in 1863.

🧴 About these

They're 2 3/4 by 1 1/4 inches, unused and never put on a bottle - crisp, uncreased and unglued, the paper toned a little with age so the type ghosts faintly through to the back. Pair one with his Glycerin of Thymol label and you have the same shop before and after it incorporated, or frame it small with a note about the Wellcome Collection's Charnley recipe books - it's a perfect present for a pharmacist, or for anybody who was once made to swallow a spoonful of castor oil. The supply is finite - nobody's printing C. Charnley labels again, and once these last unused ones are gone, they'll be very difficult to acquire.
