Effect of Broad-Spectrum Hemp Extract on Neurobehavioral Activity on the Immobilization Stress-Induced Model in Sprague Dawley Rats.

BACKGROUND

Broad-spectrum hemp extract is expected to be a promising new intervention for managing stress and anxiety. Research has shown that the cannabinoids found in , such as cannabidiol (CBD), tetrahydrocannabinol (THC), and cannabigerol (CBG), possess anxiolytic properties that can positively impact mood and stress.

METHODS

In the current study, a broad-spectrum, nondetectable THC hemp extract with other minor cannabinoids (broad-spectrum hemp extract) was administered at 28 mg/kg·bw to evaluate its anxiolytic properties. This was performed using various behavioural models and biomarkers for oxidative stress. In addition, a 300 mg/kg·bw of Ashwagandha root extract was also incorporated to compare its effects on relieving stress and anxiety.

RESULTS

The decreased levels of lipid peroxidation were measured in broad-spectrum hemp extract (36 nmol/ml), Ashwagandha (37 nmol/ml), and induction control (49 nmol/ml) treated groups of animals. The levels of 2-AG decreased in the broad-spectrum hemp extract (1.5 ng/ml), Ashwagandha (1.2 ng/ml), and induction control (2.3 ng/ml) treated groups of animals. The levels of FAAH decreased in broad-spectrum hemp extract (1.6 ng/ml), Ashwagandha (1.7 ng/ml), and induction control (1.9 ng/ml) treated groups of animals. The levels of catalase increased in broad-spectrum hemp extract (35 ng/ml), Ashwagandha (37 ng/ml), and induction control (17 ng/ml) treated groups of animals. Similarly, increased levels of glutathione were found in broad-spectrum hemp extract (30 ng/ml), Ashwagandha (27 ng/ml), and induction control (16 ng/ml) treated groups of animals.

CONCLUSION

Based on the results of this study, it can be concluded that broad-spectrum hemp extract inhibited the biomarkers for oxidative stress. Also, certain behavioural parameters showed improvements with respect to both the ingredient administered groups.
