Hop (Humulus lupus) has sedative effects. That is also one more reason to harvest it in my garden and dry it up. I wait until the cones start to dry up in the plant. When they are dry enough I pick up as much as fits in one baking tray, place it in our sauna and then let them dry up there 'til the end. No extra electricity is needed. Very eco-friendly.This season I am using hop also in aroma therapeutic way. For that I need dried hop cones and left over fabric.
