In 2015, Eva Corfmat globetrotter passionate about fauna and flora, made a world tour on the 5 continents. During his trip to Vietnam, an eyelid prick causes him significant inflammation. A Vietnamese woman then offered her a remedy: an ointment made from white tea. Amazed by its effectiveness, Eva decided upon her return to France to initiate research on this rare and precious tea. She discovers that white tea, which is highly concentrated in polyphenols, is the most powerful antioxidant in the world. This is how Léonia was born, in homage to her grandmother's first name, and whose etymology means “strong and courageous woman”.
