Lavender

I just had to put a post about Lavender, because I thought about its symbolism and how it could work with the story.

Lavender is recommended for any faintness or trembling of the emotional body, and can be applied to the temples or sniffed.
Lavender's tranquil properties make it an excellent mild sedative and painkiller...lavender works wonders with skin problems, rheumatic aches, insomnia, and depression...helpful to the head and brain, for Mercury rules thinking and the mind.
"Look in the flowers and perfumes of nature for peace of mind and joy of life."
It is helpful for all disorders that trouble the head and spirit, for its scent is calming.
One of the oldest and most revered is lavender, whose symbol is devotion.

Another website offers more explanations:

It has been used for centuries in the area of love, used to scent love letters, or used as a perfume to attract the opposite sex. Back in the Renaissance days lavender would be combined with rosemary and used to secure the chastity of a woman.
