Answer 2

According to ancient literature, in order to harvest a real-life mandrake, we would tie it to a dog.

Medieval plant-collectors actually devised a huge method for harvesting the mandrakes.

The right way for getting one was to simply unearth the roots by using ivory stake, attaching this plant to the dog by using a cord.  

The horn is sounded, also drowning out shrieking when at a time startling a dog.
