Aunt Adele was a relative to Jean-Luc Picard, known for her home remedies.
Her cure for the common cold was ginger tea with honey at 80 °C. Picard replicated Adele's "medicine" for Admiral Kennelly, who was suffering from a Cardassian virus. (TNG: "Ensign Ro")
For people having problems sleeping, she had a recipe for a warm milk toddy. One of the ingredients was nutmeg. (TNG: "Schisms", "Cause And Effect")
This character was only mentioned in dialogue.
In the original script for "Ensign Ro", she was called 'Rebecca'.
