Mechanism of Action
Gotu Kola
Triterpene saponins (asiaticoside, madecassoside, asiatic acid, madecassic acid) are the primary bioactives. They increase BDNF expression in the hippocampus via CREB and ERK/MAPK pathways, promoting neuroplasticity, synaptogenesis, and memory formation. They enhance collagen type I synthesis through stimulation of fibroblasts and improve microcirculation via VEGF and angiopoietin modulation. Anxiolytic effects occur through positive allosteric modulation of GABA-A receptors (possibly at the benzodiazepine or neurosteroid site) and reduction of acoustic startle response (amygdala modulation). Gotu kola inhibits acetylcholinesterase (AChE), mildly increasing synaptic acetylcholine. Anti-inflammatory effects come from NF-kB inhibition (IkB stabilization) and TNF-alpha suppression. Asiatic acid may also activate PPAR-gamma.
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.
Risks & Safety
Gotu Kola
Common
Very well-tolerated. Mild GI upset, drowsiness.

Rare
Headache, dizziness, skin sensitivity to sunlight.
Tianeptine
Common
Nausea, constipation, abdominal pain, headache, dizziness, dry mouth.
Serious
Opioid-like effects at high doses (euphoria, dependence, respiratory depression). Withdrawal syndrome with abrupt cessation after chronic high-dose use. Abuse and overdose deaths reported.
Rare
Hepatotoxicity, skin reactions.
Full Profiles
Gotu Kola →
Centella asiatica is an Ayurvedic and Chinese medicine herb known as the 'herb of longevity.' It has been used for centuries to enhance memory, promote wound healing, and reduce anxiety. Modern research confirms it increases BDNF, enhances collagen synthesis, improves microcirculation, and has anxiolytic effects. Unlike most adaptogens, gotu kola has clinical evidence for improving memory and attention in healthy adults.
Tianeptine →
An atypical antidepressant with unique nootropic properties. Unlike SSRIs which increase serotonin, tianeptine is a mu-opioid receptor agonist and enhances serotonin reuptake. It reduces stress-induced neuronal damage in the hippocampus and amygdala, improving mood, cognition, and stress resilience simultaneously. Prescription medication in many countries but carries abuse potential at high doses.
