There’s so many things to know about hemp!
Grown specifically for industrial uses of its by-products, this incredible plant has been cultivated all around the world for tens of thousands of years. Though hemp contains tetrahydrocannabinol (THC) – the psychoactive compound in Cannabis species, the concentration is not high enough to produce intoxicating effects.
On our Instagram page, we’ve been sharing a whole bunch of interesting facts about our favourite plant. We thought we’d take our 9 favorites and put them together in one place!
Here they are…
Fact #1 – Hemp Vs. Marijuana – Is There A Difference?
Both ‘hemp’ and ‘marijuana’ come from the exact same plant. In fact, marijuana is just a slang term for cannabis that was coined in the early 1900’s during prohibition. Though hemp and marijuana are referred to as strains or species of this plant, this is a misnomer.
Nowadays, the names are used interchangeably in respect to the THC level. Hemp differs from marijuana by containing at most 0.3% THC by dry weight – this varies slightly by country.
Fact #2 – The History of Hemp
Hemp fibre imprints have been found and dated back to as far as 28,000 years ago, which are believed to be the beginning of a trend that developed over the course of time. Several remnants of hemp fabrics have also been found by archeologists, one of which dates back to 8000 BC in modern day Iraq. The Chinese also became aware of its uses around 2700 BC. Emperor Shen Nung educated citizens on its cultivation and weaving into clothing. It is believed to be one of the first fibers that was used by humans for clothing.
Fact #3 – Refined Vs. Unrefined Hemp Seed Oil
Hemp seed oil is derived from pressed seeds of the plant. It is gaining popularity around the world because of its numerous health benefits. After extraction from seeds, it can be processed into 2 variants: refined and unrefined oil.
Refined hemp seed oil is colorless and lacks the distinct flavor of hemp. It is added to cosmetic products because it has a long shelf-life and is more chemically stable. However, once refined, hemp seed oil loses many of it’s nutrients and fatty acids – this is what makes hemp seed oil so good for your skin! That’s why we like to say only use unrefined hemp seed oil for skincare, and keep refined oils for production of innovative new products like bio-biodegradable plastics, or sustainable fuel sources.
Unrefined hemp seed oil has a greenish hue with a nutty flavor. This oil is rich in nutrients unlike the refined version. It has heart-healthy components like Omega-3 and Omega-6 essential fatty acids. It is rich in antioxidants like vitamin E. It is also great for using as a natural skin and hair care product. We use unrefined hemp seed oil in all of our skincare, hair care, body care, and food products!

Fact #4 – Hemp Seed = Hemp Flour & Hemp Protein
Three main consumables can be made from hemp seed. Including the seed itself, hemp flour and hemp protein are also common forms in which hemp seed can be found. Hemp seeds have to be hulled to derive the edible, nutritionally rich inner kernels. Also known as hemp hearts, they can be added into cereals, salads and yogurt.
Hemp flour is derived from raw hemp seeds. This is after the seeds have their oils pressed out. It is also known as hemp bran or hemp powder. It can serve as a source of gluten free flour with just one tablespoon containing 60% of our daily fibre requirement.
Hemp protein is the full ground hemp seed which means it still contains the oil. It is more nutritious than the flour because of the presence of the oil.
Fact #5 – Hemp Absorbs Carbon Dioxide From The Air
Carbon sequestration is the process whereby carbon dioxide in the atmosphere is absorbed by plants. Plants use the energy from the sun to transform CO2 and water into hydrocarbons in a process known as photosynthesis. This essentially means that capable plants are able to remove carbon dioxide from the air, essentially curving greenhouse gas emissions.
Sure enough, hemp is excellent at sequestering carbon. One hectare of industrial hemp can absorb approximately 15 tonnes of CO2. The then formed biomass can be used for several purposes.

Fact #6 – Well, theory…
Historical documents and accounts show that the large areas of New South Wales may have been intended for more than just housing for prisoners. Some believe that this land mass was supposed to be used to support large scale hemp production for the British.
This might seem like a surprise to most Australians since they have become used to thinking of hemp as something criminal. Want to learn more? Check out this article!
Fact #7 – Hemp Can Make Plastic!
Biodegradable plastics decompose over time to form water carbon dioxide and biomass. This means they do not persist and clog up the environment . Hemp can be turned into biodegradable plastics through a variety of processes. Once the fibres have been removed from the stem, one of the leftover parts of the plant is cellulose. Cellulose can be used to make a growing number of bio-composites, and is a strong option for sustainable packaging as we move into the future. Hemp grows very easily, which makes it a sustainable means of deriving plastics.
Fact #8 – Hempcrete Is Healthier!
Hempcrete is made from a mixture of industrial hemp fibres and limestone. It is very durable and creates a negative carbon footprint. This is due to its ability to absorb and store carbon dioxide. Using hemp for building dates back to ancient eras. Even the Colosseum had some structures made out of hemp. In 2010, the first modern hemp house was built in North Carolina.
At Margaret River Hemp Co, we love hempcrete. In fact, our sister company ‘Hemp Homes Australia’ also does a lot of work with it! Learn more about hempcrete here.
Fact #9 – Hemp Can Save The Bees!
Over the years, there has been a rapid decline in honey bee population. This could be terrible for the world’s food supply. Though hemp relies on winds for pollination, it has been found that bees particularly love its pollen.
As bees populations continue to decline, industrial hemp seems like a great option to solve this problem. Hemp is a pest resistant, annual plant so bees can use their pollen and nectar when other crops are not in season.
There’s a lot more to why bees love hemp!
