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.
The gamma-linoleic acid content of hemp seed works as a hormone regulator for the thyroid and pancreas, and it can reduce many of the symptoms that come from a hormonal imbalance, including severe menopausal symptoms, mood swings, depression, and anxiety. It also can help regulate the hormones that affect weight gain and hunger. Overall, by re-balancing your hormones, your body will work at its optimal and ideal level.
With 78% essential fats hemp oil greatly exceeds soy oil at 40%, canola oil at 30%, olive oil at 10% and other oils. Omega 3 and Omega 6 essential fats may reduce cholesterol, blood pressure, coronary heart disease and stroke. The 3:1 ratio of Omega 6 to Omega 3 EFA's in hemp oil is thought to be the best in nature for promoting cellular health. Hemp oil contains more "Omega 3" EFA components (19%) than are found in any fish and in most fish-oil supplements.
