As we step into 2025, I find myself reflecting on the nature of change and healing. The turning of the year offers us a powerful metaphor – like the Earth continuing its ancient dance around the sun, transformation happens in cycles rather than straight lines. While our culture often pushes for dramatic resolutions and immediate transformations, I’ve learned that, at least for me, sustainable change tends to unfold more like the seasons: gradually, naturally, and sometimes chaotically, but always with its own inherent wisdom.
This understanding has shifted how I approach try to approach change in my own life. Rather than setting rigid goals, I’ve found more success in cultivating strategies and practices that align with my natural rhythms. When we give ourselves permission and space to grow organically rather than forcing immediate transformation, we often find ourselves making more meaningful and lasting changes.
This understanding of cycles and sustainable transformation feels especially relevant as we shift our focus from exploring depression to exploring specific herbs for depression. The medicines we’ll discuss don’t often force rapid changes but rather support gradual rebalancing and healing. But before we talk about individual herbs, let’s connect what we’ve learned about brain networks with how we choose herbs for support.
Remember our discussion of the brain’s networks? Depression often involves disruptions in how these networks interact. The Default Mode Network – that self-reflection network – can get stuck in patterns of rumination. The Salience Network, which helps us process emotional information, might misinterpret or dampen emotional signals. And the Executive Network, critical for focus, motivation, and emotional regulation, often shows reduced function.
These networks rely on specific neurotransmitter systems to function optimally, which is why over the next few posts, we’ll explore herbs in three main categories:
- Serotonergic herbs that help regulate emotional processing and reduce rumination
- GABA-ergic herbs that support the calming side of our nervous system
- Dopamine/norepinephrine stimulants that affect focus, motivation and pleasure circuits
Today we’ll focus on serotonergic herbs, which tend to be especially helpful when depression comes with a side of anxiety and fear. This pattern often shows up as:
- Circular worried thoughts that won’t quiet down
- Anxiety layered on top of low mood
- Difficulty feeling safe or settled
- Sleep disruption (especially trouble staying asleep)
- A tendency for the mind to spiral into worst-case scenarios
This combination of depression and anxiety makes sense when we look at serotonin’s role in both emotional regulation and our sense of safety. When this system isn’t functioning optimally, both mood and anxiety regulation can suffer.
The herbs in this category – like Lavender, Mimosa, Saffron, Kanna, and St. John’s Wort – help restore balance to these systems. Let’s look at one of my favorites – Saffron!
I think of Saffron as the bringer of warmth and clarity—like sunlight breaking through clouds. This isn’t just poetic language – when people describe their experience with saffron, they often mention a sense of mental clarity returning alongside emotional warmth, as if a fog is lifting while their capacity for the warmer, more vibrant emotions simultaneously expands.
The research on saffron for depression is remarkably robust – multiple clinical trials have shown it performs as well as conventional antidepressants like fluoxetine (Prozac) and imipramine, but with fewer side effects. Saffron seems to work through multiple mechanisms rather than just affecting a single pathway.
Saffron influences several neurotransmitter systems simultaneously:
- It modulates serotonin reuptake, similar to SSRIs but more gently
- It appears to directly influence GABA receptors, reducing anxiety
- It has anti-inflammatory effects that may help address underlying contributors to depression
A Quick But Important Sidebar About “Anti-Inflammatory” Herbs
I need to pause here for a moment and address something that drives me a bit crazy. In the herbal world, the term “anti-inflammatory” gets thrown around so casually it’s almost lost meaning. Scroll through any herbal social media and you’ll find endless lists of “anti-inflammatory herbs” based on little more than Petri dish studies or theoretical mechanisms.
Here’s the thing—just because something shows anti-inflammatory effects in a test tube doesn’t mean it actually reduces inflammation in living humans. Take turmeric and curcumin, for example—they look amazing in preclinical studies, but in actual human clinical trials, their effects on objective inflammatory markers range from underwhelming to non-existent. And sure, many herbs like aloe vera might calm an inflamed sunburn when applied topically, but that’s very different from having systemic anti-inflammatory effects when taken internally.
This is why I get excited about saffron. It’s one of the few herbs where we have actual clinical evidence of reducing systemic inflammation in humans, demonstrated by significant reductions in C-reactive protein (CRP) – one of our primary markers of systemic inflammation. This puts it in a small but impressive club alongside herbs like willow and boswellia – plants where we not only understand the mechanisms but have solid clinical evidence of real anti-inflammatory effects in living humans.
While these anti-inflammatory effects likely contribute to saffron’s antidepressant action, what really interests me about saffron is how its effects align so perfectly with certain depression patterns. It seems particularly helpful when depression manifests with:
- Mental fog or difficulty concentrating (traditionally associated with dampness or “phlegm”)
- Emotional numbness rather than intense sadness (like how cold causes numbness)
- Loss of pleasure in previously enjoyable activities (a dimming of vitality)
In Avicenna’s writings, there’s a beautiful concept that captures something important about how these herbs work. He spoke of certain herbs as “exhilarants” – medicines that “incline the spirit towards joy.” Saffron was considered one of the most potent of these exhilarants.
I love this phrasing – “inclining the spirit towards joy.” Not forcing happiness, not chemically manufacturing it, but gently warming and dissolving obstacles, creating an invitation towards joy. There’s deep wisdom in this framing. It suggests that these herbs aren’t standalone cures but rather supporters of an active participatory process. They can incline our spirit towards joy, but they ask us to do the pursuing. Like a compass pointing north, they provide direction, but we must make the journey.
This traditional understanding aligns beautifully with what we now know about saffron’s effects on brain networks and neurotransmitter systems. It’s not simply “fixing” depression but rather helping create conditions where natural resilience and emotional warmth can re-emerge.
The main challenge with saffron is, of course, cost. As the world’s most expensive spice, getting a therapeutic dose through cooking alone isn’t always practical. However, the typical dose used in clinical trials is only 30mg-100mg, a very low dose.
In our next post, we’ll explore GABA-ergic herbs and why they’re often valuable allies when working with serotonergic support. As we begin this new year, perhaps we can take a lesson from saffron—sometimes sustainable change comes not from forcing transformation but from gently inclining ourselves toward what brings us warmth and clarity.
With warmth and wishes for a joy-filled New Year,
