Lister tried diluting the carbolic acid with water for the following five days. Unfortunately, this did little to offset the irritation caused by the antiseptic. So Lister turned to olive oil to dilute the chemical compound. This appeared to have a soothing effect on the wound without compromising the antiseptic qualities of the carbolic acid. Soon, the redness on Greenlees’s leg faded, and the wound began closing up.
The new solution had done the trick. Six weeks and two days after the cart had shattered his lower leg, James Greenlees walked out of the Royal Infirmary.
Glasgow had olive oil??? I'm gob-smacked!!! ;P
