In the days before the innovations of modern medicine, the yesteryear pharmacologist was called a herbalist; and this individual developed a knowledge of different confections of plants to cure ailments.
One day, an individual came in to their local shop and complained to the apothecary of a headache that had been growing in intensity over the past couple of weeks.
“When did you start feeling this?” asked the herbalist.
“It was in the evening after I came home from work, the Monday before last.”
The herbalist then asked about how healthy their lifestyle was;
It was not the best, but certainly not the worst.
The apothecary then asked their final question:
“Would it be possible for you to stay elsewhere rather than your home for a few days?”
The individual was first taken aback at this, but was eased after the herbalist told them that this was only for their health.
“...it’s the home life ain’t it…” the individual asked sullenly.
“Why don’t you go around the back and fetch yourself a dipper of water from the pump in the back.”
The individual downed the whole dipper, and to their shock, the headache started to dull.
“You know what, I feel better already.”
“Water is great at doing that,” said the apothecary.
