Hemp is used to make a variety of commercial and industrial products, such as rope, textiles, clothing, shoes, food, paper, bioplastics, insulators, and biofuels. Hemp (Cannabis sativa), also called industrial hemp, is a plant of the Cannabaceae family cultivated for its hare fibre or its edible seeds.
Hemp
is sometimes confused with cannabis plants that serve as sources of the drug marijuana and the preparation of hashish. Although all three products, hemp, marijuana and hashish, contain tetrahydrocannabinol (THC), a compound that produces psychoactive effects in humans, the variety of cannabis cultivated for hemp only contains small amounts of THC compared to that cultivated for the production of marijuana or hashish.The hemp plant is a robust, aromatic and erect annual herb. The thin, cane-shaped stems are hollow except at the tip and base. The leaves are composed of a palatal shape, and the flowers are small and yellow-green in colour. The flowers that produce seeds form elongated clusters in the form of spikes that grow on pistillate or female plants.
Pollen-producing flowers form clusters of many branches on stamina or male plants. The cultivation of hemp for fibre was recorded in China as early as 2800 BC. C. and was practised in the Mediterranean countries of Europe at the beginning of the Christian era, spreading to the rest of Europe during the Middle Ages.
It was planted in Chile in the 16th century and a century later in North America. Hemp is cultivated in temperate zones as an annual crop from seeds and can reach a height of up to 5 meters (16 feet). Crops grow best in sandy loam soil with good drainage and require an average monthly rainfall of at least 65 mm (2.5 inches) during the growing season. Crops grown for fibre are densely planted and produce plants averaging 2 to 3 meters (6 to 10 feet) tall with almost no ramifications.
Plants grown for oilseeds are planted further apart and are shorter, and have many branches. In fibre production, maximum yield and quality are obtained by harvesting shortly after plants reach maturity, which indicates full bloom and pollen released freely by male plants. Although sometimes torn by hand, plants are most often cut about 1 inch (2.5 cm) above the ground. The fibres are obtained by subjecting the stems to a series of operations that include shredding, drying and shredding them, and to an agitation process that completes the separation of the woody part, releasing the fibre or line long and fairly straight.
Fibre strands, generally larger than 1.8 meters (5.8 feet), are made up of individual cylindrical cells with uneven surfaces. The fibre, which is longer and less flexible than linen, is usually yellowish, greenish or dark brown or grey in colour and because it does not easily discolour to obtain sufficiently light tones, it is rarely dyed. It is strong and durable and is used as a string.
Some specially processed types of hemp have a whitish colour and an attractive sheen and are used to make linen-like fabrics for clothing. Hemp textiles can be used to make shoes. Hemp fibre is used to make recyclable and biodegradable bioplastics, depending on the formulation. The novel “hemp concrete”, a composite material of hemp and a lime binder, can be used in a similar way to traditional concrete in applications that do not withstand loads.
Hemp can also be used as an alternative to a wood pulp in some cases; it is frequently used in papermaking and is a sustainable alternative to fibreglass insulation in buildings. Although only the hemp plant produces true hemp, other plant fibres are referred to as “hemp”. These include Indian hemp (Apocynum cannabinum), Mauritian hemp (Furcraea foetida) and sunn hemp (Crotalaria juncea). Industrial hemp is a class of cannabis Sativa that contains no more than 0.3% tetrahydrocannabinol (THC).
The Department of Agriculture regulates industrial hemp production. People grow hemp for a variety of medicinal and industrial uses.
hemp seeds
are a nutrient-rich food with a variety of uses. People often use hemp seeds as part of savoury and sweet dishes because of their mild, nutty flavour.Hemp plants have existed for centuries and have many uses when it comes to our health. You may be familiar with hemp for its use in the manufacture of textiles, ropes or paper. However, what you may not know is that hemp can also be used as a food, medicine or supplement. Finally, hemp can be used to create a variety of biodegradable and environmentally friendly products, such as paper, clothing and building materials.
The lipid fractions of hemp seeds (Cannabis sativa) alleviate fatty liver disease induced by a high-fat diet by regulating inflammation and oxidative stress. Hemp seeds also contain phytosterols, which help lower the amount of cholesterol in the body by eliminating the build-up of fat in the arteries. In addition, hemp grows extremely quickly, meaning that it can be used to replace other crops that are harvested at a slower rate. The Kentucky Hempsters defend the economic, environmental, nutritional and agricultural benefits of industrial hemp.
Taking hemp seed protein along with medications that lower blood pressure can cause blood pressure to drop too low. For whatever reason, people always compare hemp and cannabis plants, which is a comparison that doesn't really make sense. Hemp oil intervention for eight weeks improves the fatty acid composition of erythrocyte phospholipids and the omega-3 index but does not affect the lipid profile in children and adolescents with primary hyperlipidemia.

Comparison of supplementation with fish oil, flaxseed oil and hemp oil on selected parameters of cardiovascular health in healthy volunteers. Hemp is a variety of cannabis that contains very low levels of THC and high levels of CBD, which is why it is often used for medical purposes.
