Seeds can be consumed whole, or refined by being pressed or crushed to produce hemp seed oil and flour. These seeds are also hulled, or shelled, to make them more palatable. The remaining shells, which are rich in fiber, can also be used for making flour.
Cannabis played a large role in the Greco-Roman cultures as a source of fiber, intoxication, and medicine. Cannabis seeds were discovered in the ruins of Pompeii, and Greek rhetorician Athenaeus made note of hemp being used to make rope between 170 and 230 CE. Roman author and naturalist Pliny the Elder also made reference to a cannabis root decoction as a treatment for joint stiffness and gout in the first century BCE.

The male hemp plants release pollen female plants use to produce seeds that are either planted for future crops or sold as food. In marijuana fields, male plants are typically eliminated to ensure the maximum production of sinsemilla (seedless) flowers.
Under the Hemp Farming Act, hemp cultivation is no longer limited to state departments and universities. In addition, the act gives hemp farmers the right to water, crop insurance, and federal agricultural grants, as well as legal access to national banking. Hemp may also be transported across state lines.
Studies have shown that hemp seeds reduce blood clotting, which can interact with blood-thinner prescriptions.
One of the omega-6 fatty acids in hemp seeds is gamma-linolenic acid (GLA,) which may have anti-inflammatory effects similar to drugs like ibuprofen. One study found a 75% reduction in arthritis-associated pain in participants after nine months of GLA supplementation.
Hemp seeds’ nutty flavor and versatility also make them a great substitute for the levels of protein, essential fatty acids, and other nutritional benefits found in meat and dairy products.
