Women who restore magic

For Zelda II The Adventure of Link on the Nintendo Entertainment System (NES).

A woman in every town but Rauru and Old Kasuto takes Link inside and fills his magic meter.

From the official guides

Here dwell folk with powers to restore spent life and magic.

In Ruto, Saria, and Mido
STOP AND REST HERE.
After
I CAN GIVE YOU MAGIC. COME BACK ANYTIME.
In Nabooru, Darunia, and New Kasuto
REST HERE.
After
HOW ABOUT THAT? ITS MY SPECIAL MEDICINE.
