In Japan, hemp was historically used as paper and a fiber crop. There is archaeological evidence cannabis was used for clothing and the seeds were eaten in Japan back to the Jōmon period (10,000 to 300 BC). Many Kimono designs portray hemp, or asa (Japanese: 麻), as a beautiful plant. In 1948, marijuana was restricted as a narcotic drug. The ban on marijuana imposed by the United States authorities was alien to Japanese culture, as the drug had never been widely used in Japan before. Though these laws against marijuana are some of the world's strictest, allowing five years imprisonment for possession of the drug, they exempt hemp growers, whose crop is used to make robes for Buddhist monks and loincloths for Sumo wrestlers. Because marijuana use in Japan has doubled in the past decade, these exemptions have recently been called into question.[151]
Hemp protein is also a complete source of all 20 known amino acids including the 9 essential amino acids (EAAs) which our bodies cannot produce. Approximately 65% of the protein in hemp seed is made up of the globulin protein Edestin, and is found only in hemp seed. Edestin aids digestion, is relatively phosphorus-free and considered the backbone of the cell's DNA. The other one third of hemp seed protein is Albumin, another high quality globulin protein similar to that found in egg whites. Hemp protein is free of the tryspin inhibitors which block protein absorption and free of oligosaccharides found in soy, which cause stomach upset and gas.
There are no known allergic reactions to hemp seed, but the contact that the seeds may have had with THC-covered plant parts could result in small residues of THC on the seeds. This means that you could possibly experience the feeling of being “high” or under the effect of the psychotropic chemical. This effect of hemp seed is quite rare and isn’t harmful, but it can be an uncomfortable feeling if not anticipated.
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.

Industrial help has many uses, from paper and textiles to plastic and fuel. In fact, it can even be used in place of traditional paper made from trees, as hemp paper can be recycled more times than that made from wood. Hemp also yields nearly four times as much as trees. Plastic produced from hemp is also biodegradable, making it better for the environment. Hemp seeds can be used in a variety of food products as well.
Hemp rope was used in the age of sailing ships, though the rope had to be protected by tarring, since hemp rope has a propensity for breaking from rot, as the capillary effect of the rope-woven fibers tended to hold liquid at the interior, while seeming dry from the outside.[44] Tarring was a labor-intensive process, and earned sailors the nickname "Jack Tar". Hemp rope was phased out when manila rope, which does not require tarring, became widely available. Manila is sometimes referred to as Manila hemp, but is not related to hemp; it is abacá, a species of banana.
Millennia of selective breeding have resulted in varieties that display a wide range of traits; e.g. suited for a particular environments/latitudes, producing different ratios and compositions of terpenoids and cannabinoids (CBD, THC, CBG, CBC, CBN...etc.), fibre quality, oil/seed yield, etc. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers.[citation needed]

In the Australian states of Tasmania, Victoria, Queensland, Western Australia, New South Wales, and most recently, South Australia, the state governments have issued licences to grow hemp for industrial use. The first to initiate modern research into the potential of cannabis was the state of Tasmania, which pioneered the licensing of hemp during the early 1990s. The state of Victoria was an early adopter in 1998, and has reissued the regulation in 2008.[77]
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.
It is sometimes supposed that an excerpt from Washington's diary, which reads "Began to seperate [sic] the Male from the Female hemp at Do.&—rather too late" is evidence that he was trying to grow female plants for the THC found in the flowers. However, the editorial remark accompanying the diary states that "This may arise from their [the male] being coarser, and the stalks larger"[120] In subsequent days, he describes soaking the hemp[121] (to make the fibers usable) and harvesting the seeds,[122] suggesting that he was growing hemp for industrial purposes, not recreational.
Hemp can be used as a "mop crop" to clear impurities out of wastewater, such as sewage effluent, excessive phosphorus from chicken litter, or other unwanted substances or chemicals. Additionally, hemp is being used to clean contaminants at the Chernobyl nuclear disaster site, by way of a process which is known as phytoremediation—the process of clearing radioisotopes and a variety of other toxins from the soil, water, and air.[46]
Although hemp and marijuana are members of the same species, Cannabis sativa, they're in effect completely different plants. There are about a dozen varieties of hemp plants that are grown for food, and all of them contain about 0.001 percent Tetrahydrocannabinol, or THC, the main psychoactive ingredient in marijuana. This means you can eat as much hemp as you want and you'll never have to worry about getting high or failing a drug test. Although certain states have begun to legalize the cultivation of industrial hemp in the last couple of years, the hemp seeds you can find at your grocery or health food store were likely grown in Canada or China.

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.
Hemp Seeds are a perfect and natural blend of easily digested proteins, essential fats (Omega 3 & 6), Gamma Linolenic Acid (GLA), antioxidants, amino acids, fiber, iron, zinc, carotene, phospholipids, phytosterols, vitamin B1, vitamin B2, vitamin B6, vitamin D, vitamin E, chlorophyll, calcium, magnesium, sulfur, copper, potassium, phosphorus, and enzymes. All amino acids essential to optimum health are found in Hemp Seeds, including the rarely found Gamma Linolenic Acid (GLA). The 17+ grams of omega fats supplied by Hemp Seeds provides sufficient, continuous energy throughout your day. Many users also experience these health benefits:

Author Paoli Ranalli in the book, Advances in Hemp Research, states that one of the major minerals that one can find in hemp seed is iron, an integral part of red blood cell construction in the human body. Iron deficiency can result in anemia, so having a proper amount of iron intake from foods like hemp seed can help prevent anemia, which displays itself in symptoms like fatigue, headaches, muscle weakness, and a wide range of other symptoms. Iron also helps in reducing stress and anxiety.
