Medicinal varieties of hemp

The so-called medicinal hemp refers to varieties of Cannabis sativa L. plant specie that have been selected because of their great number of inflorescences which produce phytochemical substances of great value, as active medicinal principles.

Feminine inflorescences have some specialized hairs on their surface, which are called glandular trichomes. They are the ones responsible for producing the different phytochemical substances, among them the cannabinoid (as THC, CBD, CBG,…), terpenes, flavonoids,…

There is a growing quantity of evidence that supports the effectiveness of various of this phytochemical substances in the treatment of a wide range of affections, which include: chronical and severe pain, epilepsy, sleep disorders, multiple sclerosis, illnesses for gastrointestinal backflow, irritable bowel syndrome, spasticity, hypertension, and schizophrenia, among others (Pacher et al., 2005; Izzo et al., 2009; Hazekamp & Grotenhermen, 2010; Caraceni et al., 2014; Bruni et al., 2018; Pagano et al., 2022).

Figures 1 and 2 show a schema of the therapeutic value and the action mechanisms of the cannabinoids in treating different pathologies and states, respectively.

Additionally, it is highly interesting the growing scientific interest towards the antimicrobial properties of the phytochemical substances of hemp. Every time there are more publications that propose these hemp substances as alternatives in the fight against antibiotic-resistant bacteria a problem that, sadly, is more frequent every day (Aliferis et al., 2020).

This not only increases interest for the pharmaceutic market side, but also these antimicrobial properties of hemp suppose an additional benefit for practically all their derived products. There is special interest in areas like :

  • the healthcare and hostelry (antimicrobial textiles like sheets, towels, working clothes, furniture, working tools…),
  • in the farming area (naturally antibiotic food for livestock, antimicrobial lodging,…),
  • in the construction area (insulations, materials with more resistance to fungi and other microorganisms…),
  • for personal-use clothes (underwear, socks, shirts, sport or working clothes,…),
  • food industry (antimicrobial packaging solutions, preventive foods,…),…
