Plant Parts

This plant, Pieris japonica, is often studied for its chemical composition, which is primarily concentrated within its foliage. The leaves are evergreen, leathery in texture, and serve as the main site for the synthesis of various secondary metabolites, such as grayanotoxins. Because these toxic compounds are located in the leaves, they are the specific part of the plant that researchers examine when studying its physiological properties and potential medicinal or toxicological effects.
