William Brooke O’Shaughnessy

Everyday I read articles about scientific breakthroughs concerning the medical properties of cannabis, this morning I read an article on how CBD is “a wonder medicine for pediatric epilepsy’ and how Amylea Nunez, aged two months was the youngest patient to be prescribed cannabis oil. However, she is not the youngest and cannabis oil as a treatment in paediatric epilepsy is not a new discovery, it is merely a rediscovery.

O’Shaughnessy graduated in 1829 with a Medical Doctorate from the University of Edinburgh. In 1831, at the young age of 22, he investigated cholera and his early work led to the development of intravenous fluid and electrolyte-replacement therapy.

In 1833, O’Shaughnessy moved to Calcutta, India to work for the British East India Company and during his time there he developed new cannabinoid extraction techniques which he used is preparations to treat patients suffering from, cholera, tetanus, analgesia, rheumatism and epilepsy in infants.

In India, he initially studied botanical pharmacology and chemistry, publishing his first paper on medical cannabis in 1839.

In his paper “On the preparations of the Indian hemp, or Gunjah” published in the Provincial Medical Journal, London on February 4th, 1843, O’Shaughnessey relates the case of a baby just over a month old who he administered  an ethanol (alcohol) cannabis based tincture.
