AI Summary

Cannabis Sativa seed oil (CSSO) from industrial hemp shows promising potential for accelerating wound healing through its rich fatty acid profile. In a controlled study using an animal wound model, CSSO-treated wounds closed 93% by day 21, compared to 87.55% in untreated controls (p = 0.005). The oil demonstrated multiple beneficial effects at the tissue level: enhanced collagen deposition, improved new blood vessel formation (neovascularization), and reduced inflammatory cell infiltration. This multi-faceted healing response suggests that hemp seed oil works through several complementary biological pathways rather than a single mechanism.

The study provides insight into how hemp seed oil promotes healing at the molecular level. Immunohistochemical analysis revealed decreased proinflammatory markers (TNF-α, IL-1β) while simultaneously boosting tissue regeneration markers (VEGF, Ki-67). Computer modeling studies (molecular docking) showed that fatty acids in CSSO bind effectively to anti-inflammatory proteins (COX-2, NLRP3) and wound-healing-related enzymes (SIRT1, GSK3β), providing a mechanistic explanation for the observed benefits. These findings suggest CSSO works by simultaneously reducing harmful inflammation while stimulating tissue regeneration processes.

While these preclinical results are encouraging for wound care applications, the research remains in early stages. The study was conducted in animals and used topical application, so human efficacy and optimal dosing remain to be determined. The work highlights hemp seed oil's therapeutic potential beyond general wellness uses, opening possibilities for targeted wound management applications. Future clinical studies will be needed to translate these promising laboratory findings into practical treatments for human patients.

📄 Original Abstract

This study investigates the wound healing potential of Cannabis Sativa seed oil (CSSO), derived from the industrial hemp variety 'NARLI'. The rich essential fatty acid profile of CSSO presents promising therapeutic opportunities; however, its specific in vivo efficacy and targeted molecular mechanisms in wound management remain underexplored. This study aimed to evaluate the in vivo tissue regeneration dynamics and the in silico anti-inflammatory mechanisms of CSSO derived from the 'NARLI' hemp variety in an excision wound model. Using an excision wound model, 42 rats were divided into two groups: control (untreated) and CSSO-treated. Wound healing was assessed through clinical wound area measurement, histopathological evaluation, immunohistochemistry (IHC), and molecular docking analyses. Wound area measurements were taken on days 7, 14, and 21. On day 21, CSSO-treated animals showed a significantly higher wound closure rate (93%) compared to the control group (87.55%) (p = 0.005). Histopathological analysis revealed enhanced neovascularization, increased collagen deposition (p = 0.008), reduced inflammatory cell infiltration (p = 0.020), and increased epithelial proliferation in the CSSO group. Immunohistochemistry findings showed a marked decrease in proinflammatory cytokines TNF-α and IL-1β (p = 0.023) and TGF-β (p = 0.030), and a notable upregulation of angiogenesis and proliferation markers VEGF (p = 0.031) and Ki-67 (p = 0.001). Molecular docking analyses revealed that CSSO-derived fatty acids showed binding affinities (-5.3 to -7.5 kcal/mol) with anti-inflammatory-related proteins (COX-2 and NLRP3) and (-3.1 to -6.1 kcal/mol) binding affinities with wound healing-related proteins (SIRT1 and GSK3β), suggesting a possible mechanistic basis underlying the wound healing potential of CSSO. Topical application of CSSO was associated with improved wound healing outcomes in rats, including enhanced wound closure and favourable histopathological and immunohistochemical changes. Further studies are needed to confirm these findings and clarify the mechanisms involved.
