Holixer®
150 mg of holy basil extract standardized to 2.5% ursolic acid — a compound that has demonstrated 11β-HSD1 inhibition in preclinical models, the enzyme that reactivates cortisol in peripheral tissues and keeps your stress response elevated long after the stressor is gone.
Primacy Research
What Holixer® Does For You
11β-HSD1 Cortisol Reactivation Block
Ursolic acid inhibits 11β-hydroxysteroid dehydrogenase type 1 — the enzyme that converts inactive cortisone back into active cortisol in peripheral tissues, reducing total cortisol load without disrupting adrenal function.
Adaptogenic Stress Normalization
Human studies consistently show holy basil normalizes dysregulated stress biomarkers across anxiety, cognitive, and sleep parameters — adapting the response to the stressor rather than simply suppressing it.
COX-2/5-LOX Dual Anti-Inflammatory
Ursolic acid inhibits both cyclooxygenase-2 and 5-lipoxygenase — the primary inflammatory prostaglandin and leukotriene synthesis enzymes — reducing the neuroinflammatory load that drives HPA hyperactivation.
Nrf2 Antioxidant Pathway Activation
Activates the Nrf2 transcriptional pathway, upregulating endogenous antioxidant enzymes (SOD, catalase, glutathione peroxidase) — breaking the bidirectional oxidative stress-inflammation cycle that sustains cortisol elevation.
Evening Cortisol Clearance for Sleep
By blocking cortisol reactivation and supporting HPA feedback restoration, Holixer® helps clear the cortisol load that competes with melatonin and fragments sleep architecture — enabling RESET’s GABA and sleep systems to work at full effectiveness.
Your Cortisol Won’t Quit
Cortisol is essential for navigating acute stress. But the modern stress pattern — sustained, low-grade, never fully resolved — keeps the HPA axis activated well into the night. Elevated evening cortisol directly competes with melatonin, fragments sleep architecture, and blocks the recovery processes that RESET is designed to enable.
Cortisol Won’t Decline
Under chronic stress, the normal diurnal drop in cortisol from afternoon into evening becomes blunted. Elevated evening cortisol inhibits melatonin secretion, delays sleep onset, and reduces slow-wave sleep — the phase where growth hormone is released and cellular repair occurs.
HPA Axis Stuck in Overdrive
The hypothalamic-pituitary-adrenal axis has a self-regulating negative feedback loop. Chronic stress desensitizes glucocorticoid receptors in the hippocampus and hypothalamus, impairing the feedback signal that should tell the adrenals to stand down.
Stress Compounds Overnight
High cortisol doesn’t just delay sleep — it elevates inflammatory cytokines (IL-6, TNF-α), degrades muscle protein, suppresses immune surveillance, and impairs memory consolidation. Every night of elevated cortisol creates a compounding deficit.
How Holixer® Works
Holy basil (Ocimum tenuiflorum) is classified as an adaptogen — a compound that normalizes dysregulated stress responses rather than simply suppressing them. Holixer®’s standardization to 2.5% ursolic acid targets the specific enzymatic mechanism that keeps cortisol elevated after the stressor resolves.
11β-HSD1 Inhibition
Ursolic acid inhibits 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), the enzyme that converts inactive cortisone back into active cortisol in peripheral tissues. By blocking this reactivation step, Holixer® reduces the total cortisol load without disrupting the adrenal axis itself.
HPA Axis Feedback Restoration
Chronic adaptogens like holy basil are thought to partially restore glucocorticoid receptor sensitivity in the hippocampus — the key feedback organ for HPA suppression. This allows the brain to re-engage the negative feedback loop that signals the adrenals to stop producing cortisol.
COX-2/5-LOX Dual Inhibition
Ursolic acid inhibits both cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) — the two primary enzymes in the inflammatory prostaglandin and leukotriene synthesis pathways. This reduces the neuroinflammatory load that drives HPA hyperactivation under stress.
Mild GABAergic Support
Holy basil contains eugenol and linalool, which have demonstrated mild GABAergic activity in preclinical models. This supports the transition from sympathetic to parasympathetic dominance in the evening — complementing RESET’s dedicated GABA stack.
Nrf2 Antioxidant Activation
Ursolic acid activates the Nrf2 pathway, upregulating endogenous antioxidant enzymes (SOD, catalase, glutathione peroxidase). Oxidative stress is both a cause and consequence of HPA dysregulation — reducing it creates a positive feedback loop toward cortisol normalization.
What the Research Shows
Holy basil has a substantial body of human and preclinical evidence among adaptogens — with 24 clinical studies across stress, anxiety, cognition, and sleep parameters. The signal is consistent: holy basil normalizes stress biomarkers without sedation or suppression.

Your Nightly Dose in RESET
Why this dose works: RESET’s 150 mg dose is positioned at the lower end of the clinical range, reflecting two design choices: First, Holixer®’s role in RESET is specifically targeted at 11β-HSD1 inhibition and HPA normalization — not broad adaptogenic loading. Second, the cortisol-modulating effects of holy basil are amplified by Actiserine® (phosphatidylserine), which works on the same HPA axis through a complementary mechanism. Together, they create a dual cortisol resolution system at doses appropriate for nightly use.
How Holixer® Connects Across the System
Holixer® doesn’t work in isolation inside RESET. It sits at the center of the cortisol resolution strategy — upstream of the GABA system, downstream of the stress response, and in direct partnership with Actiserine®.
Dual Cortisol Resolution
Holixer® inhibits 11β-HSD1 to block cortisol reactivation in peripheral tissues. Actiserine® modulates the HPA axis directly at the pituitary level to blunt cortisol secretion in response to ACTH. Two compounds, two mechanisms, one target: elevated evening cortisol.
Clearing the Runway for GABA
Elevated cortisol directly antagonizes GABAergic tone by reducing GABA-A receptor expression and sensitivity. By lowering the cortisol load, Holixer® creates the neurochemical conditions where PharmaGABA®, Lemon Balm, and Magnolia Bark can function at full effectiveness.
24-Hour HPA Axis Architecture
APEX contains Rhodiola Rosea and Ashwagandha for daytime HPA modulation — reducing the cortisol burden generated during the day. Holixer® in RESET handles the evening reactivation problem. Together, they create a continuous 24-hour cortisol management strategy across the full diurnal cycle.
Key Takeaways
Consistent Positive Signals Across Reviewed Studies
Consistent positive signals across reviewed studies (based on a narrative review including animal, in-vitro, and human studies — not a systematic review) across stress, anxiety, cognition, and sleep parameters.
Normalize, Don’t Suppress
Unlike pharmaceutical cortisol blockers, Holixer® works by inhibiting the reactivation enzyme (11β-HSD1) and restoring HPA feedback sensitivity — returning the system toward baseline rather than artificially suppressing it.
Ursolic Acid: The Targeted Mechanism
Holixer®’s standardization to 2.5% ursolic acid isn’t marketing — it’s the specific compound responsible for 11β-HSD1 inhibition, COX-2/5-LOX suppression, and Nrf2 activation. Unstandardized holy basil products may lack sufficient ursolic acid to produce these effects.
The Off-Switch for the Performance Stack
APEX is designed to maximize daytime cognitive output — which necessarily involves HPA activation and cortisol production. Holixer® in RESET is the designed off-switch: clearing the cortisol load generated during the day so the recovery cycle can begin.
Frequently Asked Questions
What is Holixer® holy basil extract?
Holixer® is a standardized extract of Ocimum tenuiflorum (holy basil, also called Tulsi) standardized to 2.5% ursolic acid — the specific compound responsible for 11β-HSD1 inhibition, COX-2/5-LOX suppression, and Nrf2 activation. Holy basil has been used in Ayurvedic medicine for centuries and has been studied in numerous human clinical trials.
How does Holixer® reduce cortisol?
Holixer® works primarily by inhibiting 11β-HSD1, the enzyme that reactivates cortisol from its inactive form (cortisone) in peripheral tissues. It also supports restoration of glucocorticoid receptor sensitivity in the hippocampus, helping the brain re-engage the negative feedback loop that tells the adrenals to reduce cortisol production.
What is an adaptogen?
An adaptogen is a compound that normalizes dysregulated stress responses — upregulating underactive systems and downregulating overactive ones — rather than simply suppressing or stimulating. Holy basil is classified as an adaptogen because it helps return the HPA axis toward baseline rather than artificially blocking cortisol.
What does the clinical research show for holy basil?
A comprehensive review (Cohen, 2014) surveyed the extensive pharmacological and clinical evidence for Ocimum sanctum, finding consistent positive outcomes across stress, anxiety, cognition, and sleep parameters. Controlled trials demonstrate reductions in generalized anxiety symptoms (Bhattacharyya et al., 2008) and improvements in cognitive performance (Sampath et al., 2015).
Why is Holixer® standardized to ursolic acid?
Ursolic acid is the specific triterpenoid responsible for 11β-HSD1 inhibition, COX-2/5-LOX suppression, and Nrf2 activation. Unstandardized holy basil products contain variable and often insufficient amounts of ursolic acid. The 2.5% standardization ensures each serving delivers a pharmacologically meaningful amount of the active compound.
How much Holixer® is in RESET?
RESET delivers 150 mg of Holixer® per serving, standardized to 2.5% ursolic acid (~3.75 mg ursolic acid). This dose is positioned for targeted 11β-HSD1 inhibition and HPA normalization, and is amplified by Actiserine® phosphatidylserine which works on the same HPA axis through a complementary mechanism.
