Pick some yarrow at the time of the New Moon. Put it under your pillow and say before going to sleep:
Good night fair yarrow,
Thrice good night to thee.
I hope before tomorrow’s dawn
My true love I shall see.
From: Moon Magick
Sew an ounce of Yarrow in a piece of flannel and place it under the pillow before going to bed. Repeat the following words, and you will receive a vision of your future husband or wife:
Thou pretty herb of Venus’ tree,
Thy true name it is Yarrow;
Now who my bosom friend must be,
Pray tell thou me tomorrow.”
From: A Modern Herbal
Yarrow, in the eastern counties of England, is termed Yarroway, and there is a curious mode of divination with its serrated leaf. The inside of the nose is tickled by the leaf while the following lines are spoken. If the operation causes the nose to bleed, it is a certain omen of success:
Yarroway, Yarroway, bear a white blow,
If my love love me, my nose will bleed now.”
