Half-Life2-5 hours (eugenol and other active compounds)2.5-3 hours (tianeptine), 7-8 hours (active metabolite MC5)
Typical DosageStandard: 300-600 mg extract daily, or 2-3 cups of tulsi tea. Standardized extracts (2.5% ursolic acid) provide more consistent dosing. Can be taken morning or evening.Prescription dose: 12.5 mg three times daily (Stablon). Extended-release: 25 mg once daily (Tianeurax). Do not exceed prescribed doses — abuse potential at higher doses due to opioid activity.

Mechanism of Action

Holy Basil (Tulsi)

Holy basil's adaptogenic effects come from multiple compounds: eugenol (anti-inflammatory via COX-2 and 5-LOX inhibition, TRPV1 modulation), ursolic acid (cortisol modulation via 11beta-HSD inhibition and glucocorticoid receptor modulation), rosmarinic acid (antioxidant via Nrf2/ARE pathway, anti-allergic via mast cell stabilization), and ocimumosides A and B (anti-stress via CRH and corticosterone reduction). It modulates the HPA axis, normalizing cortisol and corticosterone levels through hypothalamic and adrenal effects. Ursolic acid inhibits acetylcholinesterase (AChE), mildly increasing synaptic acetylcholine. Eugenol provides direct anxiolytic effects through GABA-A receptor positive allosteric modulation (possibly at the beta2/3 subunit interface) and 5-HT1A partial agonism. Ocimumosides may reduce ACTH release from the pituitary.

Tianeptine

Tianeptine is a full agonist at mu-opioid (MOR) and delta-opioid (DOR) receptors, mediating both its antidepressant/anxiolytic effects and abuse potential at high doses. Paradoxically, it enhances serotonin reuptake via SERT—opposite to SSRIs—yet still produces antidepressant effects, possibly through opioid-mediated mood regulation. Tianeptine modulates glutamatergic signaling by reversing stress-induced downregulation of AMPA receptor subunits (GluA1/GluA2) and restoring synaptic plasticity. In the hippocampus and amygdala, it prevents stress-induced dendritic atrophy, spine loss, and CA3 pyramidal cell damage—likely through opioid receptor activation and downstream HPA axis effects. It increases BDNF levels and promotes neurogenesis. The combination of opioid agonism, glutamate normalization, and neuroplasticity enhancement underlies its unique profile.
