Herba Mystica is a rare and valuable item in the Pokmon games. It can be used to make powerful TMs, and it is also a key ingredient in the creation of some of the best Pokmon in the game. There are four different types of Herba Mystica: Salty, Sour, Sweet, and Bitter.
Salty Herba Mystica is found in the Paldea region. It can be found by searching in the sparkling spots around the Asado Desert, and by defeating wild Pokmon around the Cascarrafa and Levincia Gyms.
