I am attempting to complete the "On Death's Bed" quest, and need to create the Swallow potion. However, I don't have that potion receipe listed in my Alchemy screen. I only have two formulas - Tawnty Owl and Thunderbolt.
This shows my available potions (with all the filters enabled).
How do I get the Swallow potion when I'm already several hours into the game (I've beaten the griffin in White Orchard)?
I have already seen this question, but it doesn't seem to answer my problem. It says that I should already have it.
When talking when the herbalist again, the only options I've given are the check what herbs she's selling, find out her story or leave.
