There is much written about this herb and it's healing benefits.
I keep lots of notes
and ran across this poem about :
Common Selfheal, by Cicely Mary Barker (1895-1973)
When little Elves have cut themselves,
Or Mouse has hurt her tail,
Or Froggie's arm has come to harm,
This herb will never fail.
The faeries skill can cure each ill
And sooth the sorest pain;
She'll bathe and bind,
And soon they'll find
That they are well again.
