Hemp Uses at WholesaleHemp.co.uk

"Hemp is the natural, durable soft fibre from the stalk of Cannabis sativa plants that grow upwards of 20 feet tall.
Hemp producers sell hemp seeds as a health food, as they are rich in heart-healthy, essential fatty acids, amino acids (both essential and nonessential), vitamins and minerals. Hemp "milk" is a milk substitute also made from hemp seeds that is both dairy and gluten-free.
Hemp is fairly easy to grow and matures very fast compared to many crops, most notably trees used for paper. Compared to cotton for clothing, hemp cloth is known to be of superior strength and longer-lasting. The fibres may also be used to form cordage for industrial-strength ropes. Hemp plants also require little pesticides and herbicides due to its height, density and foliage. This also makes the hemp plant very environmentally-friendly.
Hemp can be utilized for 25,000 very durable textile products, ranging from paper and clothing to bio fuels (from the oils found in the seeds), medicines and construction material. Hemp has been used by many civilizations, from China to Europe (and later North America) for the last 12,000 years of history."
