Hemp seed comes from the hemp plant, a fibrous non-psychoactive species that is now utilized for its shelled seeds, a nourishing and energizing food source. While the hemp plant itself has been grown and used extensively in all parts of the world for thousands of years, large scale use of hemp seeds has really only occurred in the last few decades. This is mostly due to the fact that the tiny seeds need to be mechanically hulled in order to make them edible and pleasant to eat.
