Holy Basil (Ocimum tenuiflorum) contains eugenol, rosmarinic acid, ursolic acid, and ocimumosides. Eugenol inhibits COX-2 and 5-LOX, providing anti-inflammatory effects. Ursolic acid activates AMPK and inhibits NF-kB. Ocimumosides (A and B) exhibit anti-stress activity by normalizing corticotropin-releasing hormone (CRH) and cortisol levels. Holy Basil also inhibits cortisol synthesis at the adrenal level, modulates GABAergic and serotonergic neurotransmission, has adaptogenic effects via normalization of hypothalamic-pituitary-adrenal axis, and exhibits hypoglycemic action via enhanced insulin secretion and peripheral glucose uptake.

Schisandra berries contain lignans (schisandrin A, B, C; gomisin A, N) that are the primary bioactives. Schisandrin B is a potent inducer of hepatic Phase I (CYP450) and Phase II (glutathione S-transferase, UDP-glucuronosyltransferase) detoxification enzymes. Schisandra activates Nrf2/ARE pathway, increases glutathione synthesis, and has hepatoprotective effects by stabilizing hepatocyte membranes. It modulates the HPA axis, reduces cortisol, enhances mental performance under stress via cholinergic and catecholaminergic modulation, and improves mitochondrial function through enhanced cytochrome c oxidase activity.
