If Quackery Poison Gets You!! Blue Poison Ointment



The Carleton Place and Beckwith Heritage Museum posted this picture yesterday and I ago curious.

This is an antique poison tin which held Blue Ointment that contained one third Mercury. It shows the skull and crossbones and, in small print below the word “Poison” it says: “A.C. Co. 70”.  Gonorrhea, syphilis, and chlamydia ran rampant during the Victorian era. … with urethral injections, irrigations, calomel, and treated mercurial ointments

This got me thinking about how our ancestors managed to maintain health on their units, especially when there were little to no effective medications available that didn’t involve the hideous sounding mercurial ointment or the downright hazardous, hyposulphate of soda.

Blue ointment is the name for a skin treatment that was used in the early part of the 20th century. Comprised of a mixture of mercurial ointment and petroleum or lard in a ratio of 2:1, respectively, blue ointment was often used to kill body lice, cure syphilis, and soothe troublesome skin irritations that did not respond to other poultices or salves. It was also put on the neck for lice removal especially with soldiers.



The tin was made by the McDonald Mfg in Toronto, Ontario. No idea where the ointment was made.


MacDonald Mfg. Co. Limited
Other names MMCo.
Dates & places of birth and death Established 1899, but had a fire
Occupation Lithographed Tinware Manufacturer
Notes This Toronto firm made large quantities of lithographed tinware, such as tea tins, biscuit tins, shortening tins. Some of its McCormick Biscuits tins were also marketed as “Patriotic Lunch Pails”, as they could be re-used for this purpose after the biscuits were used up.
The company had begun in 1899 (but had a fire). Once re-established, the factory at 401 Richmond Street was expanded in 1903 and in 1923. The MacDonald Manufacturing Company was purchased in 1944 by the Continental Can of Canada company (used a triple CCC mark) and they owned the factory until 1967.

Some of the containers they made were:
-Snowflake Brand Shortening
-Chocolate For Our Soldiers Places of residence Toronto, Ontario
401 Richmond Street

Blue Ointment was everywhere.. It was extremely popular.

In local treatment,  the chancre (or sore) would be excised and cauterised, or frequently bathed with types of solutions. Rubbing in a mercurial ointment will hasten the disappearance of any syphilitic skin lesion. For joint affections a dressing is applied. For chronic ulcers, the use of a mercurial ointment and the local application of salvarsan for those on the leg or to the tongue. For general treatment, there were three drugs: mercury, iodine and arsenic.[5] Arsenic?? Yes! Salvarsan is an arsenic-based drug (and mishandling of the injection could and did result in arsenic poisoning on occasion). Syphilis caused open and weeping sores called chancres–these did not itch or cause pain, but were incredibly unsightly.

About lindaseccaspina

Linda Knight Seccaspina was born in Cowansville, Quebec about the same time as the wheel was invented and the first time she realized she could tell a tale was when she got caught passing her smutty stories around in Grade 7 at CHS by Mrs. Blinn. When Derek "Wheels" Wheeler from Degrassi Jr. High died in 2010, Linda wrote her own obituary. Some people said she should think about a career in writing obituaries. Before she laid her fingers to a keyboard, Linda owned the eclectic store Flash Cadilac and Savannah Devilles in Ottawa from 1976-1996. After writing for years about things that she cared about or pissed her off she finally found her calling. Is it sex drugs and rock n' roll you might ask? No, it is history. Seeing that her very first boyfriend in Grade 5 (who she won a Twist contest with in the 60s) is the head of the Brome Misissiquoi Historical Society and also specializes in local history back in Quebec, she finds that quite funny. She writes every single day and is also a columnist for Hometown News and Screamin's Mamas. She is a volunteer for the Carleton Place and Beckwith Heritage Museum, an admin for the Lanark County Genealogical Society Facebook page, and a local guest speaker. She has been now labelled an historian by the locals which in her mind is wrong. You see she will never be like the iconic local Lanark County historian Howard Morton Brown, nor like famed local writer Mary Cook. She proudly calls herself The National Enquirer Historical writer of Lanark County, and that she can live with. Linda has been called the most stubborn woman in Lanark County, and has requested her ashes to be distributed in any Casino parking lot as close to any Wheel of Fortune machine as you can get. But since she wrote her obituary, most people assume she's already dead. Linda has published six books, "Menopausal Woman From the Corn," "Cowansville High Misremembered," "Naked Yoga, Twinkies and Celebrities," "Cancer Calls Collect," "The Tilted Kilt-Vintage Whispers of Carleton Place," and "Flashbacks of Little Miss Flash Cadilac." All are available at Amazon in paperback and Kindle. Linda's books are for sale on Amazon or at Wisteria · 62 Bridge Street · Carleton Place, Ottawa, Canada, and at the Carleton Place and Beckwith Heritage Museum · 267 Edmund Street · Carleton Place, Ottawa, Canada--Appleton Museum-Mississippi Textile Mill and Mill Street Books and Heritage House Museum and The Artists Loft in Smith Falls.
