What are the benefits of larch tree?
Larch arabinogalactan is a fiber that ferments in the intestine. It might increase intestinal bacteria, such as lactobacillus, and have other effects that could be beneficial to digestive tract health. Larch arabinogalactan is an excellent source of dietary fiber, and has been approved as such by the FDA. It has been shown to increase the production of short-chain fatty acids, principally butyrate and propionate, and has been shown to decrease the generation and absorption of ammonia.It may be useful in treating upper respiratory infections and dyslipidemia. However, very limited clinical trials, primarily conducted in healthy individuals, support these uses. Larch arabinogalactan is approved by the US Food and Drug Administration (FDA) as a source of dietary fiber and for use in food products.Larch arabinogalactan is sometimes used for medicine. Larch arabinogalactan is used for common cold, flu (influenza), ear infection (otitis media), and many other conditions, but there is no good scientific evidence to support its use.
What are the disadvantages of larch?
Drawbacks. Workability: The density and resin content can make it more challenging to work with, especially for detailed woodworking. Movement: Larch can be prone to movement (expanding and contracting) with changes in humidity and temperature, which may require careful design considerations. The properties of larch wood Larch wood is a very dense and hard wood – along with yew, it is one of the heaviest and hardest domestic softwoods. By nature, it is extremely weather-resistant and durable. It is also largely resistant to pests. This makes it ideal for outdoor use.Larch wood has very good strength properties, but these vary greatly depending on the location, as does the density (400 to 820 kg/m³), which averages 550 kg/m³. The wood is considered to be medium hard (Brinell hardness 19 N/mm²) with good stability.The main larch wood disadvantages include excessive resin content that clogs tools, dramatic dimensional instability causing warping and cracking, rapid tool dulling, inconsistent grain patterns, limited availability driving up costs, heavy weight for handling, and strong aromatic odor.The timber from larch (Larix decidua) is highly valued for its tough durable and waterproof qualities making it the perfect choice for external cladding, boatbuilding and fencing. Larch is a mountain tree and seems to prefer long cold winters which have been thought to aid with the ‘ripening’ of the timber.
Does larch need treatment?
Because of the oily, resinous and dense properties that larch has, it does not need to be treated and therefore a very popular choice. Ideal for protecting cedar or larch materials from weathering, Treatex Larch Oil offers high UV and water resistance with a no-flaking policy. Suitable for indoor and outdoor use on unfinished timber, it is recommended for timber prone to decay, fungi, or wood rot.Larch wood is tough and relatively durable. The wood is used in boatbuilding, cladding, decking, garden furniture, fencing, and construction. Products extracted from larch include arabinogalactan, rosin, turpentine, and an essential oil.
What is larch extract?
Larch arabinogalactan (larch gum) is a polysaccharide (long chain of sugar molecules) consisting of arabinose and galactose. It is extracted from the woody parts of the larch tree and is a good source of dietary fiber. Gastrointestinal health support: As a dietary fiber, Larch arabinogalactan may be an effective prebiotic, contributing to gut health.
