The Practical Potioneer was a wizarding journal that was presumably dedicated to the study of potions. Albus Dumbledore published at least one paper in it during his illustrious youth. It was considered a "learned publication" by respected wizard Elphias Doge.
During the Calamity in the 2010s, an article was published in the journal linking being a Foundable to a higher incidence of twisted spleens. However, the article provided no data to back up this claim. The article also contained information about modifying healing salves for internal injuries, which was later utilised by members of the Statute of Secrecy Task Force to increase the effectiveness of their Healing Potions.
