Research Objective

To compile and review phytocompounds and plant extracts that have shown substantial efficacy against depression targets, exploring their potential as therapeutic agents with high efficacy and low adverse effects.

Methodology

This is a review article that compiles and analyzes existing research on natural phytocompounds and plant extracts for depression. It draws upon experimental results and studies to support its claims.

Discussion

The review highlights the limitations and side effects of current antidepressant medications (TCAs, SSRIs, MAOIs, SNRIs, atypical antidepressants) such as hyponatremia, sexual dysfunction, and weight gain. It emphasizes the growing interest in natural products due to their potential for high efficacy and low adverse effects. Various phytocompounds (e.g., Embelin, Curcumin, Ferulic acid, Quercetin, Resveratrol) and plant extracts (e.g., Ocimum Basilicum, Blueberry, Ginkgo biloba) are discussed for their antidepressant properties, often linked to their antioxidant, anti-inflammatory, and neuroprotective mechanisms.

Key Findings

Natural phytocompounds and plant extracts demonstrate significant efficacy against depression targets through various mechanisms, including increasing BDNF levels, reducing oxidative stress, and modulating the HPA axis. Many of these natural agents show promise for developing safer and more affordable antidepressant drugs with fewer side effects compared to current synthetic medications.

Conclusion

Natural sources of antidepressant agents have a long history of traditional use and offer significant potential for developing safer and more affordable antidepressant drugs. Phytocompounds and plant extracts, particularly those affecting neurotransmitters like serotonin and norepinephrine, are promising alternatives to current synthetic drugs due to their potentially fewer adverse effects.

Fact Check

* Major depressive disorder (MDD) affects over 350 million individuals globally (as of 2010).
* Tricyclic antidepressants (TCAs) were first marketed in 1959.
* SSRIs are widely used due to their effectiveness in treating various psychiatric illnesses, especially MDD.
