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.[28] 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.[29]
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.
Hemp plants can be vulnerable to various pathogens, including bacteria, fungi, nematodes, viruses and other miscellaneous pathogens. Such diseases often lead to reduced fiber quality, stunted growth, and death of the plant. These diseases rarely affect the yield of a hemp field, so hemp production is not traditionally dependent on the use of pesticides.

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.[47] 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.[48]
Air-dried stem yields in Ontario have from 1998 and onward ranged from 2.6–14.0 tonnes of dry, retted stalks per hectare (1–5.5 t/ac) at 12% moisture. Yields in Kent County, have averaged 8.75 t/ha (3.5 t/ac). Northern Ontario crops averaged 6.1 t/ha (2.5 t/ac) in 1998. Statistic for the European Union for 2008 to 2010 say that the average yield of hemp straw has varied between 6.3 and 7.3 ton per ha.[73][74] Only a part of that is bast fiber. Around one tonne of bast fiber and 2–3 tonnes of core material can be decorticated from 3–4 tonnes of good-quality, dry-retted straw. For an annual yield of this level is it in Ontario recommended to add nitrogen (N):70–110 kg/ha, phosphate (P2O5): up to 80 kg/ha and potash (K2O): 40–90 kg/ha.[75] The average yield of dry hemp stalks in Europe was 6 ton/ha (2.4 ton/ac) in 2001 and 2002.[14]

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.

Hempseed's amino acid profile is comparable to other sources of protein such as meat, milk, eggs and soy.[21] Protein digestibility-corrected amino acid scores (PDCAAS), which attempt to measure the degree to which a food for humans is a "complete protein", were 0.49–0.53 for whole hemp seed, 0.46–0.51 for hempseed meal, and 0.63–0.66 for hulled hempseed.[22]
A panellized system of hemp-lime panels for use in building construction is currently under test in a European Union-funded research collaboration led by the University of Bath. The panels are being designed to assure high-quality construction, rapid on-site erection, optimal hygrothermal performance from day one, and energy- and resource-efficient buildings. The 36-month work program aims to refine product and manufacturing protocols and produce data for certification and marketing, warranty, insurance cover, and availability of finance. It also includes the development of markets in Britain, France, and Spain.[35]
Top 15 sources of plant-based protein People who eat or are considering vegetarian or vegan diets may be concerned about getting enough protein from their food. In this article, we look at the best plant-based proteins, including vegetables high in protein, and some ways to use them. We also discuss whether plant-based protein powders are a good option.

Hemp seed is a wonderful source of dietary fiber, both insoluble and soluble, in a ratio of 4:1, says a report published in the Biosystems Engineering Journal by a team of researchers from Ankara University, Turkey. Insoluble fiber is best for bulking up the stool and easing the passage through the digestive tract, thereby reducing symptoms of both diarrhea and constipation. Soluble fiber, on the other hand, is responsible for slowing glucose absorption and increasing the digestive and gastric juices, which further ease the passing of bowels. Soluble fiber also stimulates bile juice, which reduces the amount of LDL cholesterol (bad cholesterol) in the body. Overall, the effects of these two types of fiber on the body can help you avoid a number of mild to serious health conditions.
Hemp is considered by a 1998 study in Environmental Economics to be environmentally friendly due to a decrease of land use and other environmental impacts, indicating a possible decrease of ecological footprint in a US context compared to typical benchmarks.[65] A 2010 study, however, that compared the production of paper specifically from hemp and eucalyptus concluded that "industrial hemp presents higher environmental impacts than eucalyptus paper"; however, the article also highlights that "there is scope for improving industrial hemp paper production".[66] Hemp is also claimed to require few pesticides and no herbicides, and it has been called a carbon negative raw material.[67][68] Results indicate that high yield of hemp may require high total nutrient levels (field plus fertilizer nutrients) similar to a high yielding wheat crop.[69]
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.
Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they are distinct strains with unique phytochemical compositions and uses.[6] Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects.[6] The legality of industrial hemp varies widely between countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content.[7][8]
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. cannabidiol
