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.
PEA (Palmitoylethanolamide)
PEA activates PPAR-alpha (peroxisome proliferator-activated receptor alpha), a nuclear receptor that heterodimerizes with RXR and downregulates pro-inflammatory gene expression (NF-kB target genes, COX-2, iNOS, TNF-alpha). It has an 'entourage effect' on the endocannabinoid system — it inhibits the degradation of anandamide by fatty acid amide hydrolase (FAAH) through allosteric modulation or substrate competition, and upregulates CB2 receptor expression on immune cells. This provides anti-inflammatory and analgesic effects without directly activating CB1/CB2. PEA also activates GPR55 and GPR119. It inhibits mast cell degranulation (reducing histamine, tryptase, and cytokine release) and reduces microglial activation in the brain (inhibiting Iba1 expression and pro-inflammatory cytokine production). PEA may also modulate TRPV1.

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.
PEA (Palmitoylethanolamide) →
An endogenous fatty acid amide produced naturally in the body in response to pain and inflammation. PEA activates PPAR-alpha receptors and indirectly enhances endocannabinoid signaling without binding to cannabinoid receptors. It has strong evidence for neuropathic pain, neuroinflammation, and neuroprotection. Unlike anti-inflammatory drugs, it resolves inflammation rather than merely suppressing it.
