Mechanism of action
and carnosol are potent free-radical scavengers and have been studied for activation of the Nrf2 antioxidant-response pathway, which upregulates the body's own detoxifying enzymes. shows anti-inflammatory activity in laboratory models, partly through inhibition of inflammatory mediator production. has documented mild inhibitory activity on , the enzyme that breaks down the neurotransmitter acetylcholine, a mechanism proposed as one basis for traditional associations with mental clarity.
