Potion Ingredients Count

Classic potion ingredients (fantasy & tabletop)

In Harry Potter, Severus Snape’s first-year speech sets the tone for potion-making: “I can teach you how to bottle fame, brew glory, even stopper death.” The canonical recipes don’t forgive shortcuts. Polyjuice Potion wants lacewing flies, powdered bicorn horn, knotgrass, fluxweed, leeches, shredded Boomslang skin and a hair from whoever you mean to impersonate, then one month of maturation. Felix Felicis is fussier still, taking six months to brew right.

Dungeons & Dragons 5e runs on a far more mechanical economy. A Potion of Healing costs 25 gp, restores 2d4 + 2 HP, and brews in about 1 day per 25 gp of cost under the Xanathar’s downtime rules. The greater versions climb to 5,000 gp and weeks of work.

FAQ

Where do the Polyjuice ingredients come from? They’re from Harry Potter and the Chamber of Secrets, chapter 10 (“The Rogue Bludger”), where Hermione brews the potion in Moaning Myrtle’s bathroom.

Are D&D potion prices official? Yes. They come from the SRD 5.1 / DMG magic-item tables, and Xanathar’s supplies the crafting downtime rules on top.

Can I brew these in real life? No. A lot of the listed ingredients are made up, others are regulated, and some are plain dangerous. Treat the output as flavour text for storytelling.
