How to create a swallow potion mod ?

I have a problem with that, cuz I sold this potion in begining of game.

I tried to paste the line
"<loot_entry name="Recipe Swallow" chance="100" quantity_max="1" quantity_min="1" respawn_time="3600" />"
in Encrypted Manuscript.rar mod, but its adding another potion, not swallow.


Any solutions ?
