Hemp is used in thousands of ways these days. To explain how this is possible we must start by explaining the two main qualities of hemp.
The hemp seed is not actually a seed but a fruit. Hemp seeds are extremely nutritious for human as well as animals. Hemp seeds are made up from 25% protein, 30% carbohydrates and 15% insoluble fiber. The hemp seed contains calcium, magnesium, phosphorus, potassium, vitamin A, and is our best vegetable source of the essential fatty acids, containing Omega 3 linoleic acid (55%) and Omega 6 linolenic acid (25%) in a near perfect ratio, and even containing the rare nutrient gama linolenic acid.
Essential fatty acids are necessary for maintaining healthy life and are found in few food sources such as fatty fish and flax oil. Hemp seeds are used whole or crushed to make cookies, burgers, porridge, cakes, casseroles or even roasted and eaten whole (sometimes with garlic or tahini seasoning). A good example of the hemp seeds use is hemp protein powder. The hemp seed is used for hemp seed oil for nutrition, soaps, cosmetics, paints, varnishes, etc.
The principal product made from hemp seeds today is undoubtedly the oil. Hemp oil has a high nutritional value because its 3:1 ratio of omega-6 to omega-3 essential fatty acids, which matches the balance required by the human body.
Natural fiber from the stalks is extremely durable. It can be used for all kinds of wonderful things. Textiles, clothing, canvas, rope, cordage, for archival grade paper, & composite fibers replacing heavier toxic fibers and building materials made with recycled plastic and fiber. This means there is reason to believe that you might in the future see a house that is completely constructed with hemp!
Hurds serve as amazing source for renewable materials. The bulk of the woody stalks can be used for paper, animal bedding, oil absorbent, soil amendment, chemicals, plastics, & fuels (ethanol, methane, co-firing with coal, etc.) These fuels burn cleaner and are more efficient that other fuels not made with hemp. – Source Hemp.com
