Plant hemp for eradicating impurities and revitalizing the earth


Hemp has many well-documented uses from which both our own bodies and the world around us can benefit.

Hemp is a phenotype of the cannabis sativa plant species that is legally classified as less than 0.3 percent THC (tetrahydrocannabinol), although in general most of the hemp contains between 0.2 and 1 percent THC. Hemp strains that produce flowers with a higher CBD content (cannabidiol) account for almost 1 percent.

Hemp has not only enormous therapeutic value, but also numerous industrial and environmental uses, often with considerable overlaps. For example, hemp can be processed into an environmentally friendly plastic alternative. This applies to both industry and the environment.

When it comes to protecting the earth, hemp belongs to a group of plants that can be used in a process called phytoremediation. In short, hemp literally sucks toxins from the soil in which it was planted, but let's take a closer look at how this works.

What is phytoremediation?

Phytoremediation is a method for cleaning contaminated soil, air and water with various plants. The Webster definition is "the use of green plants (called hyperaccumulators) and the associated microorganisms, along with appropriate soil improvements and agronomic techniques to either contain, remove or neutralize toxic environmental contaminants".

It is a safe, inexpensive and sustainable solution that uses a plant-based approach to deal with the growing burden of human waste and pollution. While not a complete solution to this global problem, it plays an important role in our efforts to replenish the environment for future generations.

Phytoremediation has been used successfully worldwide to restore multiple locations, e.g. B. abandoned metal mines, locations where contaminants were dumped or leaked during manufacture, and areas affected by radiation. Numerous field tests have confirmed that plants can be used to detoxify the environment from pollutants such as pesticides, metals, solvents, explosives and crude oil.

Not all plants have the ability to clean up the earth. Hemp is one such plant, along with mustard, cress, pork cabbage, and a few others. Even varieties that belong to the same species can have different abilities to draw pollutants. Many plants and subspecies succumb to the damage caused by the pollutants they accumulate and therefore die before a significant difference is found. This is why the winter hardiness of a plant plays a big role in its success when used for this purpose.

Although phytoremediation is a wonderful tool, it has certain limitations. Phytoremediation effects are limited to the surface and depth that the root system of the plant occupies. So the bigger and more expansive, the better it is in this case. Neither do they completely eliminate the toxins they draw, but they accumulate in their leaves, stems or stems. This limits the use of these plants once they are ripe and ready for harvest. Phytoremediation also depends heavily on the toxicity of the poisoned soil and the condition of the soil.


The use of industrial hemp is becoming an increasingly important topic of discussion and research. There are some studies on hemp phytotherapy. So let's take a look at what the experts have to say.

From a study published in the Industrial Crops and Products Journal in 2002: “Hemp was used to test its ability as a renewable raw material to decontaminate soils contaminated with heavy metals. The influence of heavy metals on fiber quality was of particular interest. The heavy metal content was determined by means of atomic absorption spectroscopy (AAS). Four different parts of the plant were examined: seeds, leaves, fibers and cullet. "

The study states
further: “The concentration relation was Ni> Pb> Cd.
However, the heavy metal accumulation in the various parts of the plant was
extremely different. All parts of hemp plants contain heavy metals and that is
why their use as commercially viable plant material is limited. We found
that the highest concentrations of all investigated metals have accumulated in the EU
Leaves. Hemp showed a phytosanification potential in this field trial
of 126 g Cd (ha growing season). "

Another study published in 2015 in the Clean Soil, Air, Water Journal reflected these results. “The goal of this research is to investigate the potential of hemp as a heavy metal decontaminant by identifying the two heavy metal-responsive genes glutathione disulfide reductase (GSR) and phospholipase D-α (PLDα). The results showed an accumulation of heavy metals; Cu (1530 mg kg – 1), Cd (151 mg kg – 1) and Ni (123 mg kg – 1) in hemp plant leaves collected from the contaminated site. This shows the hemp plant's ability to tolerate heavy metals, possibly due to the presence of stress tolerance genes. "

All of these numbers and phrases are really just an expression that it worked when hemp was put to the test … and it worked well. The phytoremediation of hemp not only effectively pulled heavy metals out of the ground, the plant itself was only minimally damaged, and the deep root system was able to cover a large area.

Hemp phytoremediation around the world

Although hemp phytotherapy is rarely used around the world, the technique has long been known to farmers and some countries have been experimenting with it on a larger scale since the 1990s. Allison Beckett, cultural expert at Marijuana.Com, said: “Industrial hemp has been used in areas with high levels of radiation, with promising results. Hemp not only pulls toxic heavy metals out of the soil, but also improves the soil structure so that it can be used again as productive arable land. Hemp is also a vigorous plant that absorbs CO2 quickly and is therefore an encouraging solution for climate change. "

The nuclear catastrophe of Chernobyl in Ukraine is particularly well known, which contrary to popular belief is actually no longer abandoned. In fact, almost 4,000 people live and work in the region. This gives the issue of cleaning up the area a new urgency to make it safe for residents.

In February 1996, Princeton, NJ-based Phytotech, Inc. reported that various plants were able to remove up to 95% of the soil toxins in just 24 hours. In 1998, Phytotech planted industrial hemp around the Chernobyl explosion site together with the Ukrainian Institute for Bast Cultures and Consolidated Growers and Processors (CGP).

Immediately after the explosion, radiation values ​​of 300,000,000 uSv / h were measured, which were sufficient to kill a person in seconds. The radiation in the region is still present today, but has decreased significantly to around 0.3 uSv / h to 1.5 uSv / h. A team of German researchers confirmed these results in 2001.

Although time is an important factor in radiation dissipation, it has been believed that industrial hemp has been instrumental in driving these efforts forward.

As tourism to the region increases, caution is still required in certain parts of Chernobyl, particularly near the reactor.

What happens to hemp after phytoremediation?

As already mentioned, hemp absorbs the soil contamination, which is then stored in various parts of the plant, especially in the leaves. This means that these plants are not suitable for human consumption and cannot be used to manufacture food, medicines and supplements, cosmetics or clothing.

However, it is known that hemp produces a lot of biomass. This can be used as the base material for the production of biofuel. Another interesting use for contaminated hemp is the generation of electricity by burning the plant material in boilers. Some state-of-the-art studies have shown that hemp is a good source for the generation and storage of clean energy.

As long as safety comes first and
First and foremost, human interaction with the end product is minimal
can have many industrial uses for this contaminated hemp.

Last Thoughts

I can only say that hemp is incredible! What can this plant not do, from healing our bodies to healing the planet we live on? When it comes to improving hemp and the environment, I'm very excited to see what the future holds, and you should be too!
