Abstract
Background: Obsessive-Compulsive Disorder (OCD) is a common psychiatric illness characterized by obsessions or compulsions that significantly disrupt or impair daily functioning. Coleus forskohlii, a significant medicinal crop, has forskolin in its roots. It is utilized extensively as food and medicine all over the world. Coleus forskohlii has reputed medicinal uses, which include antidepressant, antiaggregant, cAMP-genic, anticancer, etc.
Objective: This study used mice models of marble burying and nestlet shredding to assess the potential efficacy of Coleus forskohlii against obsessive-compulsive disorder. 8-hydroxy-2-(di-npropylamino) tetralin (8-OH-DPAT) induced compulsive checking can demonstrate OCD-like repetitive and obsessive behavior as well as neurotransmitter imbalance (serotonin).
Methods: Each group had six mice, and the therapy was administered to the animals for a total of 15 days. On days 1, 7, and 14, the marble burying test was assessed for 30 minutes, and on days 2, 8 and 15, the nestlet shredding test was assessed for 30 minutes. The T-maze paradigm was used to assess anti-OCD activity. The brain histology and morphometry were also performed.
Results: When compared to the control group, treatments with Coleus forskohlii (50 and 100 mg/kg, p.o.) significantly enhanced performance on both behavior tests. The SAB score is dramatically increased following the administration of the 8-OH-DPAT (2 mg/kg, i.p.) group. Coleus forskohlii (50 and 100 mg/kg, p.o.) and fluoxetine (15 mg/kg, p.o.) groups showed significantly lowered results. Animals treated with 8-OH-DPAT showed a considerable reduction in serotonin levels. Following Coleus forskohlii administration, the histology of the brain tissues showed normal morphological structure with no toxicity or abnormalities.
Conclusion: The combination of all these findings points to Coleus forskohlii delivering a possible therapeutic option for the treatment of OCD. The identification and anticompulsive properties of the components from Coleus forskohlii should be the main aim of future studies.
