Summary
Hemp flower oil shows potential for agricultural workers
Area of Science:
- Agricultural health
- Pain management
- Phytochemistry
Background:
- Musculoskeletal pain is prevalent among agricultural workers globally.
- Limited access to safe, non-opioid pain relief in resource-scarce settings.
- Hemp flower oil offers potential analgesic and anti-inflammatory properties.
Purpose of the Study:
- To comprehensively analyze evidence on hemp flower oil for musculoskeletal pain in agricultural workers.
- To explore phytochemical, mechanistic, genomic, and sustainability aspects.
- To identify knowledge gaps and research priorities.
Main Methods:
- Systematic scoping review with narrative synthesis.
- Adherence to PRISMA 2020 guidelines.
- Analysis of 44 studies (2000-2025) using interdisciplinary approaches.
Main Results:
- Preclinical evidence (68%) supports mechanistic rationale for hemp flower oil.
- Limited clinical trials (23%) and genomic research (9%) available.
- Genomic research suggests links between polymorphisms and cannabinoid genotypes.
Conclusions:
- Hemp flower oil demonstrates preliminary potential for pain relief.
- Current clinical evidence is limited and of low certainty.
- Further research is needed to establish efficacy and safety for agricultural workers.
