Granny

Granny is an old woman who appears in Ocarina of Time. She lives and runs the Potion Shop in the back side of Kakariko Village. By the time when Link is a child, her shop is closed and she left a message behind on her door letting customers know that she is out in the fields to study and collect herbs for her potions. When Link is an adult, he is able to see her for the first time inside her Potion Shop. She wish to make an explicit potion, and when Link hands her the Odd Mushroom recieved by Grog in the Lost Woods, she will comment on how the guy is a bum for going into the woods, and will then ask Link if he can give Grog her most powerful potion she ever created, the Odd Potion. After that, she will sell Link the Ultimate Potion, also known as the Blue Potion for 100 Rupees. She is an old friend of the Lake Scientist in the Lakeside Laboratory, being her student once in a time.
