Flash in the Pantry

I need some lovage I'll get some tansy
We need more from the core
Where's the mother of thyme behind you
The gold of pleasure that golden rod
Flag of the marsh or mercury's dog
Grab a whispy cloud five fingers round
Now you weave just what you knead

The eye bright sparkle on hearts of ease
With a turn of the hand
See the jack of the hedge beside you
The lady's mantle or maiden's smock
Growing about the thick of the ox
Fresh morning dew three acorns full
Don't forget to keep fire below

Watch out for lightning on butcher's broom
Sure there's more on the floor
Let the moonwort revolve around you
Asarabacca phlogiston flare
Hair of the hog catch Solomon's ear
Take a shaft of sun
We knew it all along
That it must end with a flash
