CBD may help reduce high blood pressure by widening blood vessels, relieving anxiety and stress, and acting on the endocannabinoid system. The endocannabinoid system is a network of receptors and molecules that regulate various bodily functions, including mood, pain, inflammation, and blood pressure. Some studies have shown that CBD can lower blood pressure in healthy volunteers and people with anxiety or stress. However, more research is needed to confirm the long-term effects of CBD and its safety and interactions with other medications.
