Pokémon Legends: Arceus’ open-world approach has taken the Pokémon series in a new direction. Pokémon are visible in the overworld and more interactable than ever before. New features and changes to mechanics are also present, including crafting. Those looking to craft potions will need to find medicinal leeks.
You can find medicinal leaks in Pokémon Legends: Arceus throughout the wild and from shops. They can be found in grassy areas, and an icon will appear when you close. Once the prompt appears, simply press A to collect the medicinal leek.

You will need medicinal leeks and oran berries if you want to craft potions. Potions are one of the main healing items in Pokémon Legends: Arceus, so stocking up on these is not a bad idea. Keeping your Pokémon in good health is essential to progressing in Pokémon Legends: Arceus.
So when you are traveling through the Hisui region, keep your eyes out for medicinal leeks. Picking them up whenever you spot them is a good way to make sure you always have potions on hand.
