Prompt : Poisonous

I started with the mushrooms,

Ground finely don’t you see.

Then I gathered leaves

From the poisonous tree.

I picked it clean,

With no thought at all,

To what that would mean.

I mixed them all up

Adding belladonna seeds,

With just enough water

To make it liquid to suit the needs.

So in my pocket is the vial,

Hand mixed by me,

Made up of mushrooms and

The poisonous tree.

What will I do?

With the vial you ask,

I will hold it safe

Until the goodbye last.
