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.
Panax Ginseng
Ginsenosides (Rb1, Rg1, Rg3, Re, and others) have diverse pharmacological actions. They modulate the hypothalamic-pituitary-adrenal (HPA) axis, reducing cortisol release under stress through glucocorticoid receptor modulation. Ginsenosides inhibit acetylcholinesterase (AChE), increasing acetylcholine levels in the hippocampus and enhancing muscarinic and nicotinic receptor function. They enhance nitric oxide production via endothelial nitric oxide synthase (eNOS) for cerebral vasodilation. Rb1 and Rg1 promote BDNF and NGF expression through activation of CREB and TrkB/TrkA signaling, supporting neuroplasticity. Rg1 specifically enhances hippocampal neurogenesis via the PI3K/Akt pathway and Wnt/β-catenin signaling, and improves spatial learning in animal models. Ginsenosides may also modulate GABA-A receptors and have antioxidant properties.
Risks & Safety
Gotu Kola
Common
Very well-tolerated. Mild GI upset, drowsiness.
Serious
Rare hepatotoxicity reported — avoid with liver disease and limit use to 6-week cycles.
Rare
Headache, dizziness, skin sensitivity to sunlight.
Panax Ginseng
Common
Insomnia, headache, gastrointestinal discomfort, increased heart rate.
Serious
May interact with blood thinners, diabetes medications, and MAOIs. Estrogenic effects — caution with hormone-sensitive conditions.
Rare
Manic episodes in bipolar individuals, severe hypertension.
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.
Panax Ginseng →
Korean or Asian Ginseng, one of the most extensively studied herbal medicines in the world. The ginsenosides in Panax Ginseng modulate the HPA axis, enhance working memory, and improve sustained attention. Unlike many adaptogens, it has mildly stimulating properties and is best used for active cognitive demand rather than relaxation.
