Jeju is more than a place of natural beauty. It’s a living wellness system shaped by geology, climate, and a cultural rhythm that favors presence over pressure. Named a UNESCO Biosphere Reserve and a World Natural Heritage Site, the island doesn’t just preserve its environment, it lives in sync with it. The island’s dark, porous soil yields botanicals long trusted in local remedies, from tangerine peels to mugwort and wild herbs used in both cuisine and skincare.
