Mandrake Root lyrics

I've got a Mandrake Root
It's some thunder in my brain
I feed it to my babe
She thunders just the same
Food of love sets her flame
Ah, stick it up
[ Lyrics from: http://www.lyricsmode.com/lyrics/d/deep_purple/mandrake_root.html ]
I've got the Mandrake Root
Baby's just the same
She still feels a quiver
She's still got the flame
She slows down, slows right down
I've got the power
