Oil of Sweet Vitriol: Ether and Chloroform

Today, we’re going historical and looking at the two first common general anesthetics that were used: ether and chloroform.

Ether was discovered in 1275. It was first synthesized by German physician Valerius Cordus in 1540. He named it “oil of sweet vitriol” which likely gives a clue to its odor. Other sources report ether’s odor as pungent, sweet, nauseating and fruity.

The first use of ether as an anesthetic occurred in 1842 by Dr. Crawford Williamson Long who used it to remove tumors from the neck of patient James Venable in Jefferson, Georgia. You may also see references that ether was used at the Ether Dome by William Thomas Green Morton who was a dentist that assisted surgeon John Collins Warren who also used it to remove a neck tumor. Now, it is largely recognized that Long should be credited with its first use.

Ether’s main drawback was its flammability. When the advent of using cauterizing tools came to fruition, you can see how setting fire to one’s patient during surgery would be considered poor form on the part of the doctor.

Chloroform was discovered in 1831 by James Young Simpson, a Scottish gynecologist and obstetrician, and was found efficacious in 1847. Chloroform was used widely until it was determined to be toxic to the kidneys and liver, but I did find a short note that perhaps chloroform was the preferred anesthetic in England. Chloroform is reported to have a “pleasant, non-irritating odor and slightly sweet taste”.

These agents, most likely ether in the US, were in use until the mid 1950’s when the non-flammable anesthetic agent halothane was discovered.

Do you have a historical medical scene using ether or chloroform?

  1. Hey Jordyn, Love these posts. I love the British monarchy and have loads of books on the subject. Queen Victoria hated being pregnant and giving birth. With the laboring her 8th and next to last child, she was given chloroform and was delighted with it and wished it had been given to her with all her labors. I remember watching Dr Quinn Medicine Woman giving it to an asthmatic. Not sure that was a reality but they were supposed to be true to history. Susan Snodgrass


  2. Very Interesting! Though I don’t know now looking back how Chloroform would have helped an asthmatic other than relaxing them or to not be anxious, but I don’t think it would have done anything to actually reverse the asthma attack. Thanks for sharing!
