EQUILIS - Stress & Nervous System Balance

A plant native to South Africa with centuries of documented use among indigenous populations for mood enhancement, anxiety relief, and emotional balance. Contains a class of alkaloids — principally mesembrine and mesembrenone — that operate through three distinct and complementary neurological mechanisms. Kanna is one of very few botanical ingredients with a pharmacological profile that directly targets the serotonin, cAMP, and amygdala pathways simultaneously — making it the cornerstone of a mechanistically rigorous emotional balance formula.

1. SEROTONIN REUPTAKE INHIBITIONMesembrine acts as a serotonin reuptake inhibitor (SRI), blocking the transporter that removes serotonin from the synapse after transmission. This allows serotonin to remain active at the receptor for longer, strengthening signalling in mood-regulating pathways. The result is improved mood, reduced anxiety, and greater emotional stability — through a mechanism pharmacologically analogous to SSRIs but derived from a natural alkaloid fraction.
2. PDE4 INHIBITION & cAMP SIGNALLINGKanna alkaloids inhibit phosphodiesterase-4 (PDE4), the enzyme that breaks down cyclic AMP (cAMP) — a key intracellular signalling molecule governing neuronal communication, stress response, and mood-related pathways. By maintaining higher cAMP levels, Kanna supports more stable and efficient neuron-to-neuron communication in brain regions governing emotional regulation. This mechanism is independent of the serotonin pathway, providing a second distinct biological route to reduced anxiety and improved cognitive calmness.
3. AMYGDALA MODULATIONKanna has been shown to reduce excessive activity in the amygdala — the brain's primary threat-detection and fear-processing region. Overactivation of the amygdala drives anxiety, stress sensitivity, and emotional reactivity. By attenuating this overactivity, Kanna reduces the intensity of the stress response and improves emotional control — allowing performers to stay composed under pressure without pharmacological sedation.

• Enhances mood and promotes a positive, stable mental state
• Reduces stress, anxiety, and emotional reactivity
• Supports emotional balance without sedation
• Promotes calmness and inner stability under pressure
• Three-pathway mechanism: serotonin, cAMP, and amygdala modulation

A medicinal herb with over 3,000 years of documented use in Ayurvedic medicine as a primary adaptogen for stress, resilience, and emotional balance. Primary active compounds — withanolides — operate through the HPA axis and GABAergic system to reduce cortisol and promote nervous system calm. Among the most extensively clinically validated adaptogenic herbs, with multiple randomised controlled trials demonstrating significant reductions in cortisol, anxiety scores, and subjective stress in healthy adults. The most impactful ingredient in any stress-reduction formula precisely because it addresses the primary physiological driver of emotional dysregulation: cortisol overproduction.

1. HPA AXIS REGULATION & CORTISOL REDUCTIONWithanolides modulate the hypothalamic-pituitary-adrenal (HPA) axis — the hormonal cascade governing cortisol release. Under chronic stress, this system becomes overactivated, producing sustained cortisol elevations that disrupt mood, increase anxiety, impair sleep, and create a self-reinforcing stress cycle. Ashwagandha restores more calibrated HPA axis function, reducing cortisol output and preventing the body from remaining locked in a prolonged stress state. RCTs have demonstrated 14–32% reductions in serum cortisol with standardised ashwagandha extract — clinically meaningful reductions that translate directly to reduced anxiety and improved emotional stability.
2. GABAergic ACTIVATION & NERVOUS SYSTEM CALMWithanolides enhance GABAergic signalling — the brain's primary inhibitory neurotransmitter system. GABA slows neural activity, reducing excessive stimulation and the overactivated nervous system state associated with chronic stress and anxiety. By enhancing GABA-A receptor activity, Ashwagandha promotes a calming effect on the central nervous system — reducing overthinking, mental tension, and anxiety without sedation.

• Reduces cortisol levels and stress-system overactivation
• Supports calmness and significantly reduces anxiety
• Promotes emotional stability and mental balance
• Enhances resilience to sustained stress and pressure
• Supports overall mood and mental wellbeing

A flowering plant used in herbal medicine for centuries to support relaxation, reduce nervous tension, and promote emotional balance. Contains flavonoids — principally apigenin and chrysin — that interact with the GABAergic system through two complementary mechanisms: enhancing GABA receptor activity and inhibiting GABA reuptake. The combination extends the duration of inhibitory signalling, producing a sustained calming effect that outlasts single-pathway GABA support. A double-blind RCT demonstrated equivalence to oxazepam (a benzodiazepine) for generalised anxiety treatment — validating the clinical magnitude of its anxiolytic effect.

1. GABA-A RECEPTOR ACTIVATION & ENHANCED INHIBITORY SIGNALLINGApigenin and chrysin bind to GABA-A receptors, enhancing the inhibitory signal that GABA generates — slowing neural firing and reducing excessive brain activity. This produces anxiolytic and calming effects through the same receptor class targeted by benzodiazepines, but via a natural flavonoid interaction that does not carry dependency risk. In simple terms: Passion Flower helps the brain's braking system work more effectively.
2. GABA REUPTAKE INHIBITION — SUSTAINED CALMCompounds within Passion Flower inhibit the reuptake of GABA from the synapse, allowing it to remain active for longer. This extends inhibitory signalling and sustains the calming effect beyond the initial receptor activation — producing a more durable and stable state of reduced anxiety rather than a brief calming peak.
3. MILD MAO INHIBITION & MONOAMINE SUPPORTPassion Flower mildly inhibits monoamine oxidase (MAO), the enzyme that breaks down serotonin and dopamine after synaptic transmission. Reduced MAO activity extends neurotransmitter availability, supporting mood regulation and emotional stability — complementing Kanna's serotonin reuptake inhibition with an upstream preservation mechanism.

• Reduces anxiety and nervous tension via GABA modulation
• Promotes sustained relaxation through reuptake inhibition
• Supports emotional balance and stress relief
• Reduces mental overstimulation and overthinking
• Clinically validated anxiolytic effect — comparable to oxazepam in RCT

A traditional medicinal herb from the bark of the Albizia tree, used in Chinese medicine for centuries to relieve emotional distress, calm the mind, and promote inner peace. Known in traditional practice as the 'happiness bark,' it contains saponins, flavonoids, and lignans that influence both serotonergic and GABAergic systems. In Equilis, Albizia Bark works in a complementary direction to Kanna — while Kanna prevents serotonin reuptake, Albizia supports serotonin receptor function and signalling efficiency, providing additive support to the same mood-regulation pathway through a distinct upstream mechanism.

1. SEROTONERGIC MODULATION — MOOD UPLIFTFlavonoids and saponins in Albizia julibrissin enhance serotonin receptor function and signalling within mood-regulating brain regions. Rather than acting on the reuptake transporter (as Kanna does), Albizia supports the receptor-side of serotonergic communication — improving how effectively neurons respond to available serotonin. The result is improved mood baseline, reduced emotional lability, and a greater sense of emotional steadiness.
2. GABAergic ACTIVITY — CALMNESS WITHOUT SEDATIONAlbizia compounds enhance GABA signalling, reducing excessive neural activity and supporting a calm, controlled mental state. The effect is additive to Passion Flower's GABA-A receptor activation and reuptake inhibition — reinforcing the formula's GABAergic stack through a third distinct mechanism of inhibitory support.

• Enhances mood and promotes emotional wellbeing
• Reduces stress, anxiety, and emotional distress
• Supports calmness without sedation or impaired clarity
• Promotes emotional balance and inner stability
• Additive serotonergic support to Kanna's reuptake-inhibiting mechanism

A traditional medicinal herb used in Chinese medicine for over 2,000 years to support mental clarity, emotional balance, and cognitive function. The root contains saponins (principally tenuifolin), polygalacic acids, and flavonoids — compounds that operate across the cholinergic, serotonergic, and HPA systems simultaneously. Polygala is the cognitive-clarity ingredient within the Equilis formula: it ensures that the calming effect of the broader stack does not come at the cost of focus and mental sharpness. It specifically prevents the 'sedated' outcome by maintaining acetylcholine availability and supporting BDNF-driven neural connectivity.

1. AChE INHIBITION — COGNITIVE CLARITY UNDER CALMTenuifolin inhibits acetylcholinesterase (AChE) — the enzyme that breaks down acetylcholine after synaptic transmission. This extends acetylcholine activity in memory and attention circuits, supporting mental clarity and cognitive sharpness. In the context of a calming formula, this mechanism is critical: it preserves cognitive performance while the rest of the stack reduces stress and anxiety — enabling a state of calm focus rather than relaxed sedation.
2. BDNF SUPPORT & SYNAPTIC PLASTICITYPolygala compounds increase brain-derived neurotrophic factor (BDNF) expression — a protein essential for neuron survival, growth, and synaptic connectivity. Low BDNF is associated with stress, low mood, and cognitive decline. By supporting BDNF pathways, Polygala enhances the brain's structural resilience and its capacity to maintain neural connections under sustained emotional and cognitive demand.
3. HPA AXIS MODULATION & STRESS ATTENUATIONPolygala modulates HPA axis activity and supports serotonergic balance, reducing excessive stress signalling and promoting a calmer physiological baseline. This adaptogenic dimension reinforces the formula's broader cortisol-management mechanism, adding a third independent pathway of HPA regulation alongside Ashwagandha and Schisandra.

• Enhances mental clarity, focus, and cognitive performance
• Supports memory, learning, and neural communication
• Promotes emotional balance and mood stability
• Reduces stress and supports calm, focused thinking
• Maintains cognitive sharpness within a calming formula

A medicinal berry used in traditional Chinese medicine for centuries to support stress resilience, mental performance, and overall vitality. Contains lignans — schisandrin, schisandrol, and gomisins — that regulate the stress-response system, support cerebral blood flow, and protect neurons from oxidative stress. Among all adaptogens in the Equilis formula, Schisandra is uniquely positioned to support performance under pressure: it targets both the hormonal (HPA axis) and neurological (cerebral circulation) sides of cognitive performance under stress. It also extends multi-system support across noradrenergic, dopaminergic, GABAergic, and glutamatergic pathways — making it one of the broadest-acting adaptogenic herbs available.

1. HPA AXIS MODULATION & STRESS RESILIENCESchisandrin and gomisins normalise HPA axis function under chronic stress — reducing excessive cortisol release and improving the body's adaptive stress response. This prevents the energy drain, mood disruption, and emotional instability caused by prolonged stress-system overactivation. Unlike acute anxiolytics, Schisandra builds resilience over time, improving the organism's baseline capacity to handle stress.
2. CEREBRAL CIRCULATION & NEURONAL EFFICIENCYSupports cerebral blood flow, ensuring consistent delivery of oxygen and glucose to neurons under stress and fatigue. Improved cerebral circulation directly supports cognitive clarity, focus, and the ability to remain mentally sharp under sustained psychological demand — the precise state that stress typically disrupts.
3. MULTI-SYSTEM NEUROTRANSMITTER SUPPORTSchisandra lignans influence noradrenergic, dopaminergic, GABAergic, and glutamatergic systems simultaneously — providing broad-spectrum neurotransmitter stabilisation. This cross-system action addresses the multi-pathway nature of mood dysregulation, where anxiety and low mood rarely stem from a single neurotransmitter disruption but from a systemic imbalance across the signalling landscape.

• Enhances stress resilience and emotional stability
• Supports calm, focused mental performance under pressure
• Improves mood, mental clarity, and sustained focus
• Reduces fatigue and supports balanced energy
• Multi-system adaptogen — broadest neurotransmitter coverage in the formula

The flower of Albizia julibrissin, a distinct preparation from the bark (He Huan Pi) with overlapping but differentiated phytochemical activity. Used in Chinese medicine to promote what traditional texts call a 'calm happiness' — a gentle uplift in mood and emotional ease without stimulation or agitation. Contains flavonoids, saponins, and lignans that work through serotonin-adjacent and GABA-adjacent pathways with a softer, more emotionally nuanced profile than the bark fraction. The inclusion of both Albizia preparations in Equilis delivers full-spectrum coverage across the tree's known mood-active compound profile.

1. NEUROTRANSMITTER SUPPORT — MOOD & RELAXATIONFlavonoids and saponins in the flower fraction influence serotonin and GABA-related pathways, supporting a more balanced and positive emotional baseline. The flower preparation complements the bark's more direct serotonergic receptor action with a gentler, broader neurotransmitter stabilisation — maintaining the calm-uplifted state rather than acutely driving it.
2. NERVOUS SYSTEM CALMING & EMOTIONAL REGULATIONAlbizia flower reduces excessive neural activity associated with stress and emotional tension — helping the nervous system settle without producing sedation or cognitive impairment. Supports the emotional regulation circuits of the limbic system, helping maintain a stable response to emotional stimuli and reducing irritability and mood fluctuation.

• Promotes a gentle, sustained uplift in mood and emotional wellbeing
• Reduces stress, anxiety, and emotional tension
• Supports calmness without sedation
• Enhances emotional balance and inner stability
• Full-spectrum Albizia coverage alongside the bark fraction

A medicinal herb used in Ayurvedic medicine for thousands of years, considered the most sacred plant in the tradition. Contains eugenol, ursolic acid, rosmarinic acid, and flavonoids — compounds that operate through the HPA axis, neurotransmitter systems, and antioxidant pathways. Within Equilis, Holy Basil complements Ashwagandha's cortisol-reducing action with a distinct compound profile, reinforcing HPA axis regulation through eugenol and ursolic acid rather than withanolides. The anti-inflammatory dimension is particularly relevant: chronic inflammation disrupts serotonin synthesis and neurotransmitter balance — Holy Basil addresses this biological link between inflammation and mood.

1. HPA AXIS MODULATION — COMPLEMENTARY CORTISOL REDUCTIONEugenol and ursolic acid regulate HPA axis activity, reducing excessive cortisol production through a compound profile distinct from Ashwagandha's withanolides. The combination of two independently validated adaptogenic herbs with complementary active compounds provides broader and more durable HPA axis normalisation than either alone.
2. SEROTONIN & GABA NEUROTRANSMITTER SUPPORTHoly Basil supports balanced activity in serotonin and GABA pathways, contributing to mood stability and reduced anxiety through the same systems targeted by Kanna, Passion Flower, and the Albizia preparations — reinforcing formula-level coverage of the serotonergic and GABAergic landscape from an additional mechanism.
3. ANTI-INFLAMMATORY & ANTIOXIDANT NEUROPROTECTIONRosmarinic acid and flavonoids reduce neuroinflammation and oxidative stress — two physiological states that directly impair serotonin synthesis and neurotransmitter function. By addressing the inflammatory underpinning of mood dysregulation, Holy Basil supports the biological conditions required for stable emotional function over time.

• Reduces stress and cortisol through a distinct adaptogenic mechanism
• Supports serotonin and GABA balance for mood and anxiety relief
• Reduces neuroinflammation linked to mood disruption
• Promotes calmness and emotional resilience
• Supports long-term mental wellbeing and vitality

A medicinal mushroom used for thousands of years in traditional Chinese medicine, referred to as the 'mushroom of immortality' for its broad physiological support properties. In the context of emotional balance, Reishi's triterpenoids and polysaccharides work through the nervous system and immune-inflammatory axis — the two physiological systems most commonly overlooked in mood formulas. Research has specifically validated Reishi's effects on mood and quality of life in humans, with clinical improvements in fatigue, emotional wellbeing, and anxiety reported across multiple populations. Its inclusion addresses the immune-mood link: chronic inflammation and immune dysregulation are increasingly recognised drivers of mood disorders.

1. NERVOUS SYSTEM MODULATION — DEEP CALMTriterpenoids (ganoderic acids) regulate central nervous system activity, reducing excessive neural stimulation and promoting deep calm. Unlike GABAergic ingredients that act on specific receptor systems, triterpenoids influence broader patterns of neural tone — supporting the global shift from a stressed, overactivated nervous system to a more settled baseline.
2. HPA AXIS REGULATION & EMOTIONAL STABILITYReishi modulates the HPA axis and cortisol release, adding a third distinct adaptogenic mechanism (alongside Ashwagandha and Holy Basil) to the formula's cortisol-management stack. Its triterpenoid profile is distinct from both withanolide-based and eugenol-based HPA modulation, providing complementary and additive stress-system support.
3. IMMUNE REGULATION & THE INFLAMMATION-MOOD AXISBeta-glucan polysaccharides regulate immune activity and reduce inflammatory signalling. Chronic low-grade inflammation impairs serotonin synthesis, disrupts neurotransmitter balance, and contributes to persistent mood dysregulation. By addressing this immune-mood connection, Reishi supports emotional balance through a biological pathway entirely distinct from neurotransmitter-targeted ingredients.

• Promotes deep relaxation and nervous system calm
• Reduces stress and supports long-term emotional stability
• Supports nervous system balance and recovery
• Addresses the immune-inflammation driver of mood disruption
• Enhances resilience to prolonged stress

A nutrient-rich fruit used for centuries in traditional Chinese medicine for vitality, mood, and overall wellbeing. Contains Lycium barbarum polysaccharides (LBPs), carotenoids (zeaxanthin), flavonoids, and a dense micronutrient profile. In the Equilis formula, Goji Berry functions as the neuroprotective and cellular-vitality anchor — ensuring that the neurological systems targeted by the formula's active mood compounds are structurally supported and protected from oxidative degradation. Multiple controlled studies have demonstrated reductions in anxiety and depression scores, and improvements in mood, sleep, and energy in adults supplementing with Lycium barbarum — validating its inclusion as a clinical-grade mood ingredient rather than a nutritional afterthought.

1. NEUROPROTECTION & MOOD-PATHWAY SUPPORTLycium barbarum polysaccharides (LBPs) protect neurons from oxidative stress and support balanced neurotransmitter activity in mood-regulating brain regions. In animal models and preliminary human studies, LBP supplementation has been associated with reductions in anxiety and depression markers, and improvements in prefrontal cortex and hippocampal neuroplasticity — the two brain regions most impaired by chronic stress.
2. ANTIOXIDANT PROTECTION & CELLULAR VITALITYRich in carotenoids (particularly zeaxanthin) and flavonoid antioxidants, Goji Berry reduces oxidative stress throughout the body and brain. Oxidative stress is a primary contributor to fatigue, cognitive fog, and mood instability. By neutralising reactive oxygen species and supporting cellular energy function, Goji Berry maintains the physical vitality needed to sustain emotional resilience over time.

• Supports mood and emotional wellbeing
• Protects brain cells and supports cognitive function
• Reduces oxidative stress and supports overall vitality
• Helps reduce fatigue and maintain energy levels
