The Latin name for hemp is cannabis sativa. It grows in moderate climates. Both the fibre and the seed have been used by people around the world for thousands of years, as it is very easily grown, and has many benefits.
There are about 500 different varieties of cannabis sativa, and they can roughly be divided into 3 categories:
- useful for fibre
- useful for oil
- useful for medicine and/or recreation (also known as marijuana)
Different parts of the plant are used depending on what you want to do with it. If you are growing a fibre variety, you will use the stalk. It has thousands of used from car parts (in the form of non-wovens or compressed into polymers) to wedding dresses (in the form of a hemp-silk blend). If you are growing a food and/or oil variety, you will use the seed. If you are growing a drug variety, you will use the bud and perhaps the leaves.
