BRAVE AI:
Peppermint lowers blood pressure primarily through menthol, its main active compound, which acts as an agonist for TRPM8 receptors located on vascular smooth muscle cells. The activation of these receptors triggers a cascade that includes the entry of calcium into the endothelium, stimulating nitric oxide production and causing hyperpolarization of the smooth muscle cells, which results in vasodilation and reduced peripheral resistance.
Additionally, menthol activates TRPM8 channels on sensory neurons, which modulates the autonomic nervous system by enhancing parasympathetic (vagal) activity and reducing sympathetic drive. This shift in autonomic tone helps lower resting heart rate and further contributes to reduced blood pressure. Peppermint also possesses anti-inflammatory and antioxidant properties that protect blood vessels from oxidative stress, while spearmint (a related mint variety) contains carvone, a compound that acts similarly to calcium channel blockers to reduce vascular spasms.

Thanks. That is the important part.
And using that technical answer I looked for hypertension drugs that act as as an agonist for TRPM8 receptors located on vascular smooth muscle cells. And AI came up with none.
That says the METHOD of the vascular benefit of peppermint seems to be unique peppermint.
But it comes with a warning; high doses of peppermint oil (which concentrates the properties of peppermint) can be toxic and can be not tolerated well by the kidneys. Peppermint oil as a supplement should be sold with cautionary notes.
