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.
Reishi
Reishi's triterpenes (ganoderic acids A, C, D, H; ganoderenic acids) modulate the HPA axis by reducing CRH and ACTH release, lowering cortisol via glucocorticoid receptor feedback. Ganoderic acids have direct sedative effects through GABA-A receptor modulation (possibly allosteric at the benzodiazepine site) and 5-HT2A/2C serotonergic modulation. Beta-(1,3)-(1,6)-glucan polysaccharides bind Dectin-1 and complement receptor 3 (CR3) on macrophages, natural killer cells, and dendritic cells, activating NF-kB and MAPK signaling for immune modulation. Reishi inhibits histamine release from mast cells via Fc epsilon RI downregulation and stabilizes mast cell membranes (anti-allergic effect). Antioxidant properties involve upregulation of superoxide dismutase (SOD1/SOD2), catalase, and glutathione peroxidase. Ganoderic acids may also inhibit 5-alpha-reductase and ACE.

Full Profiles
Holy Basil (Tulsi) →
An Ayurvedic adaptogen (Ocimum tenuiflorum) revered as 'The Incomparable One' in traditional Indian medicine. Holy basil reduces cortisol, supports clear thinking under stress, and has mild anxiolytic effects. It is gentler than ashwagandha and rhodiola, making it suitable for people who find stronger adaptogens overstimulating or sedating. Often consumed as a pleasant-tasting tea.
Reishi →
Known as the 'mushroom of immortality' in Chinese medicine, Reishi (Ganoderma lucidum) is an adaptogenic mushroom primarily used for stress reduction, immune support, and sleep improvement. Unlike the stimulating effects of Cordyceps or Lion's Mane, Reishi is calming and is best taken in the evening. Its triterpene compounds modulate the HPA axis and support GABAergic relaxation.
