A Saxon charm for a difficult journey

I have found the following text in Leech Book I, LXXXVI, 

For mickle travelling over land, lest he tire, let him

take mugwort a to him in hand, or put it into his shoe,

lest he should weary, and when he will pluck it, before

the upgoing of the sun, let him say first these

words, "I will take thee, artemisia, lest I be weary on the way," etc.

I have replaced 'etc.' with the following text from HERBARIVM, CLXXIX (Periwinkle);

"that thou cometh to me glad, blossoming with thy usefulness; that thou outfit

me so that I be shielded, and ever well, and undamaged by poisons and by wrath”

Back to Leech Book I, LXXXVI,;

Sign it with the sign of the cross,

when thou pullest it up.

Both of these manuscripts are from the late Saxon period.
