Morison was born at Bognie, Aberdeenshire, in 1770, the youngest son of Alexander Morison.
After studying at Aberdeen University and Hanau in Germany, he established himself at Riga as a merchant, and subsequently in the West Indies, where he acquired property.
Ill-health obliged him to return to Europe, and about 1814 he settled at Bordeaux.

After "thirty-five years' inexpressible suffering", and experimenting with every imaginable course of medical treatment, he accomplished "his own extraordinary cure" about 1822 by the simple expedient of swallowing a few vegetable pills of his own compounding at bed-time and a glass of lemonade in the morning.
His success led him to set up in 1825 as the vendor of what he called "vegetable universal medicines", commonly known as "Morison's Pills", of which the principal ingredient was said to be gamboge.
His medicines soon became highly popular, especially in the west of England, and in 1828 he opened an establishment for their sale in Hamilton Place, New Road, London, which he dignified with the title of "The British College of Health".

Morison believed that bad blood was the cause of all disease and that purgation from vegetable laxatives was the only cure.
He advertised his pills as curing all disease.
He bought a pleasant residence at Finchley, Middlesex, called Strawberry Vale Farm, but later lived in Paris.
It was said that the profits from the sale of his medicines in France alone were sufficient to cover his expenditure there.
From 1830 to 1840, he paid £60,000 to the British government for medicine stamps.

In 1836, his business received heavy criticism as an apothecary Robert Salmon was indicted for the manslaughter of John M'Kenzie by administering large quantities of Morison's pills.

Morison died in Paris on 3 May 1840.
