Wort-cunning is the magickal use of herbs. Whether it is Frigga bestowing an Apple for fertility, Thorr being saved by a Rowan tree, or Idunna giving the Gods apples (some believe that it was actually crab-apples) to keep Their youth, all plant-life resonates certain energy patterns.
When my Northern European ancestors came to Vinland (America), they brought with them herbs for healing and herbs that were known to contain certain magickal influences. With these herbs they also brought the landspirits of the herbs.
Forget not, Mugwort, what thou didst reveal, What thou didst prepare at Regenmeld. Thou hast strength against three and against thirty, Thou has strength against poison and against infection, Thou has strength against the foe who fares through the lands!
And thou, Plantain, Mother of herbs, Open from the East, mighty within, Over thee chariots creaked, over thee queens rode, Over thee brides made outcry, over thee bulls gnashed their teeth. So mayest thou withstand poison and infection, And the foe who fares through the lands!
This herb is called Stime, it grew on a stone, It resists poison, it fights pain. It is called harsh, it fights against poison.

Now, Cock's-spur Grass conquer the greater poisons, thou thouu art the lesser; Thou, the mightier, vanquish the lesser until he is cured of both!

This is the herb which is called Wergulu; The seal sent this over the back of the ocean To heal the hurt of other poisons!
These nine sprouts against nine poisons. A snake came crawling, it bit a man Then Woden took nine glory-twigs, Smote the serpent so that it flew into nine parts, There Apple brought this to pass against poison, That she nevermore would enter her house!
Thyme and Fennel, a pair great in power, The Wise Lord holy in heaven, Wrought these herbs while He hung on the cross; He placed and put them in the seven worlds to aid all, poor and rich.

Now these nine herbs avail against nine evil spirits, Against nine poisons and against nine infectious diseases, Against the red poison, against the running poison Against the yellow poison, against the green poison, Against the black poison, against the dark poison, Against snake-blister, against water-blister, Against thorn-blister, against thistle-blister, Against ice-blister, against poison-blister, If any poison comes flying from the east or any comes from the north, Or any from the west upon the people.
Christ stood over disease of every kind. I alone know running water and the nine serpents heed it; May all pastures now spring up with herbs, The seas, all salt water, be distroyed, When I blow this poison from thee!
