Mood: mushrooms are capable of influencing it. For this reason, today we will dive into a fascinating journey through the fungal kingdom and its extraordinary effects on the human psyche. We are not just talking about the psychedelic effects of certain species, but about a complex system of neurochemical interactions involving dozens of bioactive compounds. Recent studies have shown that over 80% of the analyzed fungal species contain at least one compound with neuroactive properties, opening new frontiers in the scientific understanding of mood and its disorders.
In this article, we will explore:
- The mechanism of action of 7 classes of fungal compounds on mood
- Clinical data updated to 2025 with surprising results
- Comparative tables of species and their specific effects
- The emerging role of mycotherapy in psychiatry
Fun Fact: A cross-sectional study of 1,200 participants revealed that regular consumers of medicinal mushrooms show a 42% reduction in depressive symptoms compared to the control group (Journal of Psychopharmacology, 2024).
The neuroactive power of fungal terpenes
Terpenes represent the "aromatic signature" of the fungal kingdom, but their importance goes far beyond scent. These lipid molecules can cross the blood-brain barrier and interact directly with our neuroreceptors. In 2023, the "MycoBrain" project at Utrecht University identified 127 different terpenes with neuroactive properties in 63 fungal species.
The chemistry of mood: mapping key terpenes
Here are the most significant terpenes for mood modulation, along with their mechanisms of action:
| Terpene | Fungal Species | Average concentration (mg/kg) | Mood effects | Mechanism of action |
|---|---|---|---|---|
| β-pinene | Hericium erinaceus | 12-18 mg | +27% memory, -33% anxiety | MAO-B inhibition, ↑BDNF |
| Limonene | Pleurotus citrinopileatus | 8-15 mg | -41% neural oxidative stress | Activation of 5-HT1A receptors |
| β-caryophyllene | Ganoderma lucidum | 5-22 mg | Modulation of neural inflammation | CB2 agonist |
Surprising Fact: A 2024 meta-analysis on NCBI demonstrated that the combination of β-pinene and limonene has a synergistic effect that enhances antidepressant activity by 68% compared to individual use.
The case of Hericium erinaceus: a neural tonic
The so-called "Lion's Mane" contains two unique terpenes—erinacines and ericenones—that stimulate the production of NGF (Nerve Growth Factor) with efficacy comparable to some synthetic drugs. A randomized controlled trial published in ScienceDirect showed:
- +31% in NGF levels after 12 weeks
- 44% improvement in depression scores (HAM-D scale)
- 37% reduction in anxiety (GAD-7 scale)
The precise mechanism involves activation of the PI3K/Akt signaling pathway, crucial for neuronal survival and synaptic plasticity. Patients reported significant improvements in mental clarity and emotional stability as early as the fourth week of treatment.
The olfactory pathway: when aroma influences mood
Inhalation of volatile fungal terpenes represents an often-overlooked but highly effective administration route. Olfactory receptors are directly connected to the limbic system, the emotional center of the brain. Innovative research from the University of Munich demonstrated that:
| Terpene | Inhaled Dose | Change in Amygdala Activity | Subjective Effect |
|---|---|---|---|
| α-pinene | 0.5 mg/m3 | -22% activation | Calm, centeredness |
| Linalool | 0.3 mg/m3 | -34% activation | Deep relaxation |
This data explains why ancient traditions like mushroom aromatherapy have deep scientific roots. Inhaling specific terpenes can modulate mood in less than 10 minutes, as demonstrated by EEG measurements.
Keeping stress at bay
Ganoderma lucidum (Reishi), also known as the "mushroom of immortality" in Chinese medicine, contains ganoderic triterpenes that modulate the HPA (hypothalamic-pituitary-adrenal) axis. A meta-analysis of 9 studies (Phytomedicine, 2025) reports:
| Parameter | Improvement | Duration |
|---|---|---|
| Salivary cortisol | -28% | 6 weeks |
| Sleep quality | +44% | 4 weeks |
| Fatigue | -33% | 2 weeks |
Its beta-glucans (1,3/1,6-D) also reduce neural inflammation linked to depression (-21% IL-6). This mushroom is a true adaptogenic anti-stress agent.
Mood and energy deficiency
Mood is also strongly influenced by energy dips: this is where Cordyceps sinensis plays a key role. This parasitic mushroom increases mitochondrial ATP production by 28% and cerebral oxygen uptake. Research on athletes shows:
- +19% in mental stress resistance (Stroop test)
- +25% in dopamine levels (study in Frontiers in Neuroscience)
- 37% reduction in mental fog in burnout patients
The active compound cordycepin acts as an adenosine modulator, balancing energy and relaxation.
Beta-Glucans and the gut-brain axis
Medicinal mushrooms are rich in beta-glucans, polysaccharides that modulate the immune system and the gut-brain axis. Considering that 90% of serotonin is produced in the gut, it’s no surprise these compounds profoundly impact mood.
| Beta-Glucan | Fungal Source | Daily Dose | Mood Effect | Mechanism |
|---|---|---|---|---|
| β-(1,3/1,6)-D-glucan | Ganoderma lucidum | 500 mg | -29% anxiety | ↑ tryptophan production |
| β-(1,3)-D-glucan | Pleurotus ostreatus | 300 mg | +22% mental energy | Microbiota modulation |
A groundbreaking study published in The Lancet showed that 8-week supplementation with Reishi beta-glucans:
- Increased tryptophan levels by 40%
- Reduced inflammatory markers IL-6 by 35%
- Improved PANAS (Positive Affect) scores by 27%
Trametes versicolor - A powerful microbiota protector
The Turkey Tail mushroom, thanks to its PSK (polysaccharide-K) and PSP content:
- Rebalances the gut microbiome (+40% bifidobacteria)
- Increases tryptophan production (a serotonin precursor)
- Reduces neural oxidative stress (-29% ROS)
📊 Results: 12 weeks of supplementation in 80 patients with mood disorders showed:
- PANAS scores: +31% positive emotions
- BDNF: +18 ng/ml (p<0.01)
Mood: toward a new era
Mushrooms represent a goldmine of neuroactive compounds with extraordinary therapeutic potential. From terpenes that gently modulate mood to compounds that recharge our energy, the fungal kingdom offers many solutions for daily well-being.
Future Prospects: With over 200 clinical trials currently underway on mushrooms and mental health, and a mycotherapy market growing at 24% annually, we are only at the beginning of a revolution in this field.
Future research will need to explore:
- Synergies between different fungal compounds
- Personalized microdosing protocols
- Applications in neurology and cognitive decline prevention
One thing is certain: mushrooms, with their complex cocktail of bioactive compounds, will continue to surprise us and offer new hope for those suffering from mood disorders.
