https://en.wikipedia.org/wiki/HempHemp, or industrial hemp (from Old English hænep), typically found in the northern hemisphere, is a variety of the Cannabis sativa plant species that is grown specifically for the industrial uses of its derived products. It is one of the fastest growing plants and was one of the first plants to be spun into usable fiber 10,000 years ago. It can be refined into a variety of commercial items including paper, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.
Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they are distinct strains with unique phytochemical compositions and uses. Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects. The legality of industrial hemp varies widely between countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content.
http://www.hempsa.co.za/The Hemp plant is not only one of the oldest cultivated plants, it is also one of the most versatile, valuable and controversial plants known to man. The industrial Hemp plant has a long history, which has proven its innate worth and its stalks and seeds can serve as raw material for an exciting array of many diverse products. The plant’s Latin name "Sativa" means "useful Hemp" and it definitely measures up to its name!
The potential contribution of the Hemp Seed to human nutrition is gaining world wide recognition. Like no other plant resource, the Hemp seed has both a high content of easily digestible, complete protein and a rich endowment of oil providing the most favourable ratio of Essential Fatty Acids (EFAs) required for proper human nutrition. In addition, the Hemp Seed provides a significant contribution of Gamma-Linolenic acid which has potential therapeutic efficacy.
The Hemp Seeds are pressed to obtain oil, crushed to create flour or eaten as a nut substitute. The various grades of this EFA rich oil can be used as a nutritional supplement, in aromatherapy, in the manufacture of body care products and cosmetics, as a lubricant, in the manufacture of alkyd resins etc.
The Hemp Cake (which is the remains of the seeds once it has been through the oil press) can be used as animal feed, in plant fertilizer, in bait and much more.
Hemp is currently not grown in South Africa. It is regulated and can only be grown under license. All licenses to date have been issued for research purposes only.
All Hemp products available in South Africa are therefore imported.
http://www.arc.agric.za/arc-iic/Pages/Hemp.aspxHemp, Cannabis sativa L, is an industrial crop and is one of the oldest cultivated crops in the world. Hemp is cultivated in many countries, including, China, Canada, Russia, the USA, and several European countries. In these countries hemp farming is regulated.
It is illegal to cultivate hemp in South Africa as it is classified under the Cannabis species. A permit is required before one can plant hemp and this permit is obtained from the Department of Health under the Medicines Control Council.
The plant has been used for a wide variety of purposes. It is used to make over 25,000 consumer products, from hemp apparel and accessories to house-wares and hempseed oil cosmetics. Some of the products made from hemp are: clothing, shoes, diapers, rope, canvas, cellophane, paints, fuels, chain lubricants, biodegradable plastics, paper, fibreboard, cement blocks, food, cosmetics, and soap.
Hemp is described as an annual herbaceous plant with an upright growth habit and its characteristic leaves are composed of five to seven leaflets. The hemp plant can reach nine metres in height, but under cultivation it averages between two to four metres. Hemp is from the same plant species (Cannabis) as dagga (marijuana). Although similar in appearance, the dagga plant may develop more side branches and has a more bushy appearance in contrast with hemp. Hemp is mainly cultivated for fibre and oil and because the delta-9-tetrahydrocannabinol (THC) content is very low, it cannot be used as a drug. Dagga, on the hand, has such a low fibre content that it is not suitable for fibre production. Hemp generally refers to the fibre-producing strain of Cannabis. Currently three main groups of varieties under cultivation, namely, varieties cultivated primarily for fibre, varieties grown for seed and varieties grown for their medicinal and narcotic properties.
Not sure why it's illegal to grow such a plant, or why it has only been issued for research purposes.
