Czech biotech project developing a blood plasma substitute using edestin, a major protein extracted from industrial hemp seeds.
What is actually happening?
Plasma for People (P4P Technology, Czech Republic) is working on an intravenous colloid solution made primarily from purified edestin (sometimes spelled edestine) dissolved in saline. This aims to serve as a volume expander and protein replacement in cases of shock, burns, major surgery, or fluid loss โ similar to how human albumin or certain synthetic colloids are used today.
Edestin is a globular storage protein that makes up 60โ80% of the protein in hemp seeds. It has a hexameric structure and amino acid profile that gives it good nutritional value and some biochemical similarities to human serum globulins. Czech researchers have studied it since the 1950s; a key patent (granted 2008, building on earlier work) covers isolating edestin from hemp seeds via cold pressing/extraction methods and formulating it into a sterile IV solution.
The company reports:
โข Achieving very high purity (up to 99.9%).
โข Successful preclinical animal testing (including primates) showing good compatibility and no major immune reactions.
โข They already sell an oral dietary supplement called Bloody Vital containing edestin for general wellness/recovery use.
Current status (as of latest available information): Still in the preclinical phase. They have the IP and proof-of-concept production but are seeking funding for human clinical trials and regulatory approval. No completed large-scale human trials or market authorization have been publicly reported. Claims of ~10ร lower cost, pathogen-free production, universal compatibility, longer shelf life, and ethical advantages (no human/animal donor blood) are plausible on paper but require rigorous clinical validation.
Why hemp seeds?
Hemp seeds are already valued for protein, oil, and nutrition. Edestin stands out because it is:
โข Highly bioavailable.
โข Structurally interesting for medical use.
โข Derivable from industrial hemp (low-THC varieties) in a sustainable, fast-growing crop.
This is separate from the fiber-focused or cannabinoid sides of the plant. It highlights another potential high-value application for hemp seeds beyond food/supplements.
Hemp seeds โ the source of edestin. Industrial hemp varieties are optimized for seed/fiber, distinct from the landrace cannabis varieties you work with.
Realistic perspective
This is exciting for hempโs versatility and could eventually help address global plasma shortages (demand far outstrips supply in many regions). A stable, plant-based, lower-cost alternative with no infection risk would be genuinely useful โ especially in trauma care, developing regions, or for patients with religious/ethical objections to blood products.
However, blood plasma is complex. Human plasma contains albumin plus clotting factors, antibodies, and other components. An edestin-based solution would likely function more like a targeted albumin/colloid expander than a full synthetic plasma. Regulatory pathways for injectable biologics are strict; safety, consistency, efficacy, and manufacturing scale all need proving.
There is also unrelated materials-science work using cold atmospheric plasma (a physical plasma technology) to modify hemp fiber surfaces for better composites โ but that is not what the headlines mean.
