i dont seem to have the recipe for the endurance potion,so i ask where to find it and how to make it,i checked at home and the lizard temple,maybe is a side quest i forgot between my saves
You don't need to learn the recipe in-game to make it. Honestly, I don't know that all of them can be learned in-game.
From the menu choose the Guide, and one of the tabs on the guide spreadsheet is a recipe list that tells you how to make each herbalism product, as well as where to find or buy the different ingredients needed.
