You can press hemp seeds to extract polyunsaturated oil, besides making seed cakes out of it. Oil extracted out of hemp seeds can be mixed with other foods like breads or salads or even eaten plain. You can use grind hemp seed cakes to hemp flour and use it while baking. Another important hemp seeds health benefits is, that oil extracted out of hemp seeds can also be used as an ointment to regenerate and nourish the skin. Hemp oil can penetrate the skin quickly compared to other oils. This helps in preventing skin from sagging due to aging as essential fatty acids completely penetrate the outer skin layer, thereby, encouraging healthy moist skin.
Hemp crops are tall, have thick foliage, and can be planted densely, and thus can be grown as a smother crop to kill tough weeds. Using hemp this way can help farmers avoid the use of herbicides, gain organic certification, and gain the benefits of crop rotation. However, due to the plant's rapid and dense growth characteristics, some jurisdictions consider hemp a prohibited and noxious weed, much like Scotch Broom.
Hemp is possibly one of the earliest plants to be cultivated. An archeological site in the Oki Islands near Japan contained cannabis achenes from about 8000 BC, probably signifying use of the plant. Hemp use archaeologically dates back to the Neolithic Age in China, with hemp fiber imprints found on Yangshao culture pottery dating from the 5th millennium BC. The Chinese later used hemp to make clothes, shoes, ropes, and an early form of paper. The classical Greek historian Herodotus (ca. 480 BC) reported that the inhabitants of Scythia would often inhale the vapors of hemp-seed smoke, both as ritual and for their own pleasurable recreation.
Hemp seeds are rather oily and high in fat. One tablespoon contains 3 g to 4 g of fat. The majority of this is polyunsaturated fat --- the good kind of fat --- and according to Blue Shield of California, shelled hemp seeds contain both omega-3 and omega-6 fatty acids. However, all this fat can come at a price, and you may experience mild diarrhea when adding shelled hemp seeds to your diet. If your digestive system is sensitive to change, start with small amounts of hemp seed --- say, a teaspoon a day --- and slowly work your way up to the recommended serving of 2 tbsp.
The process to legalize hemp cultivation began in 2009, when Oregon began approving licenses for industrial hemp. Then, in 2013, after the legalization of marijuana, several farmers in Colorado planted and harvested several acres of hemp, bringing in the first hemp crop in the United States in over half a century. After that, the federal government created a Hemp Farming Pilot Program as a part of the Agricultural Act of 2014. This program allowed institutions of higher education and state agricultural departments to begin growing hemp without the consent of the Drug Enforcement Agency (DEA). Hemp production in Kentucky, formerly the United States' leading producer, resumed in 2014. Hemp production in North Carolina resumed in 2017, and in Washington State the same year. By the end of 2017, at least 34 U.S. states had industrial hemp programs. In 2018, New York began taking strides in industrial hemp production, along with hemp research pilot programs at Cornell University, Binghamton University and SUNY Morrisville.
Shelled hemp seeds are becoming a popular dietary supplement because of their high protein content and healthful fatty acids. Hemp seeds come from the same plants, Cannabis sativa or C. indica, that produce marijuana, although the plants are cultivated and processed differently so that hemp seeds contain very low levels of psychoactive cannabinols such as delta-9-tetrahydrocannabinol, or THC. Shelled hemp seeds are generally safe, but some people may experience some undesired side effects.
Eating shelled hemp seeds will not produce the same effects as smoking marijuana. According to David P. West Ph.D., a plant researcher who has studied hemp extensively, the compound in marijuana that produces its psychotropic effect, THC, is only produced in the flowers, buds and leaves of the cannabis plants, not the seeds. However, since the seeds come into contact with the rest of the plant, some residue may remain on the seeds after processing and shelled hemp seeds may contain extremely low levels of THC. The exact levels vary by brand, so if you are very sensitive to THC and happen to buy a brand with higher-than-average levels, you may experience euphoria or hallucination. It is also highly unlikely --- although not impossible --- to get a positive drug test result after consuming large amounts of shelled hemp seeds.
Further the protein content of the hemp seed is supposed to be very digestible. Many people noted their personal experience of finding that hemp seed protein did not cause bloating or gas, like some of their whey, or other protein shakes did. And, unlike soy which has super high amounts of phytic acid (that anti-nutrient that prevents us from absorbing minerals), hemp seed doesn't contain phytic acid. At the very least, this makes hemp seed a step up from soy.
Concrete-like blocks made with hemp and lime have been used as an insulating material for construction. Such blocks are not strong enough to be used for structural elements; they must be supported by a brick, wood, or steel frame. However, hemp fibres are extremely strong and durable, and have been shown to be usable as a replacement for wood for many jobs, including creating very durable and breathable homes. The most common use of hemp lime in building is by casting the hemp and lime mix while wet around a timber frame with temporary shuttering, and tamping the mix to form a firm mass; after the removal of the temporary shuttering, the solidified hemp mix is then ready to be plastered with a lime plaster.
One claim is that Hearst believed[dubious – discuss] that his extensive timber holdings were threatened by the invention of the decorticator which he feared would allow hemp to become a cheap substitute for the paper pulp used for newspaper. Historical research indicates this fear was unfounded because improvements of the decorticators in the 1930s – machines that separated the fibers from the hemp stem – could not make hemp fiber a cheaper substitute for fibers from other sources. Further, decorticators did not perform satisfactorily in commercial production.
Most health organizations agree that the human body needs a 3 or 4:1 balance of omega 6 over omega 3. Hemp seed is the only seed where this ideal balance occurs. It does not occur in flax, almond, walnut, soybean or olive oil. Daily use of flax seed can lead to dangerous imbalances since flax seed oil has a balance of 1:4 instead of a healthy 4:1 omega-6 over omega-3.

Hemp seeds are one of the best sources of plant-based protein and GLA and have a wide variety of health benefits, including their ability to improve heart health, stimulate digestion, build muscle mass, eliminate insomnia, treat anemia, and aid in weight loss. They also help to stimulate metabolic activity, boost the immune system, reduce symptoms of menopause and menstruation, improve skin and hair health, and build stronger bones.
