“Alchemy Tutorial” is a Radiant Quest in The Elder Scrolls V: Skyrim
|Orgnar||Sleeping Giant Inn (Riverwood)|
|Arcadia||Arcadia's Cauldron (Whiterun)|
|Zaria||Grave Concoctions (Falkreath)|
Talk to any of the quest givers, asking if you can use the nearby Alchemy Lab. They will tell the Dragonborn can, if they clean up after themselves. The quest giver will also mention that Wheat and Blisterwort will make a healing potion. If you don't have either of these supplies on hand, most likely the Quest giver sells them.
