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.

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.
