Introduction

Depression is a significant psychiatric illness often leading to severe consequences, including high rates of suicide. It is characterized by decreased turnover of monoamine neurotransmitters such as norepinephrine, dopamine, and serotonin. Traditional antidepressants target these systems, but they often come with undesirable side effects and varying patient responses. The search for effective herbal alternatives has gained momentum, traditional remedies being considered for their potential antidepressant properties.

Antidepressant Activity of Jasminum sambac

Jasminum sambac, utilized in traditional Malay medicine for decades, demonstrated significant antidepressant-like effects in experimental mice models. In a study, doses of 250mg/kg and 500mg/kg for seven days resulted in decreased immobility times in the Tail Suspension Test (TST) and Forced Swim Test (FST), both markers of depressive-like behavior. These effects were comparable to the classical antidepressant imipramine, indicating that Jasminum sambac may provide a viable alternative for depression treatment.

Mechanisms of Action

The mechanisms behind the antidepressant effects of Jasminum sambac involve the enhancement of serotonin and dopamine levels in the brain. Higher doses significantly increased serotonin, which plays a crucial role in cognitive functions and emotional regulation. Furthermore, there was an increase in dopamine levels, suggesting an activation pathway that could enhance norepinephrine synthesis. Notably, there was no significant effect on monoamine oxidase (MAO) levels, implying that the antidepressant effects may primarily result from increased neurotransmitter availability rather than MAO inhibition.

Antioxidant Properties

In addition to neurotransmitter alterations, Jasminum sambac exhibited antioxidant properties that may contribute to its antidepressant effects. The study found a reduction in malondialdehyde (MDA) levels, a marker of oxidative stress, and an increase in antioxidants like reduced glutathione and vitamin C in the brain. This suggests that oxidative stress plays a role in the pathophysiology of depression, and mitigating this stress with Jasminum sambac correlates positively with the observed antidepressant-like activity.

Conclusion

The findings from the study underscore the potential of Jasminum sambac as an effective natural antidepressant, operating through multiple pathways, including serotonergic, adrenergic, and dopaminergic systems, as well as through antioxidant mechanisms. This plant presents a promising alternative to conventional antidepressants, supporting the need for further research to explore its full therapeutic benefits in the context of depression and related disorders.
