The wooden box heart.

Ten drops of chestnut oil,
first simmer, then
bring to a boil.
Three spoons of tea tree from virgin woods,
throw them in pan
stay in good mood.
Cinnamon sticks, lavender dust, rosemary leaves add in with trust.
Keep in cool place, far from sun's heat,
heart box preferred, and with a blink,
you will transform it
the dead man's meat.
