About
With the grass radical 艹 indicating its plant nature, the character 藿 uses the bottom component 霍 for its phonetic value. Originally, 藿 referred to the leaves of pulse plants, especially bean leaves, which were a common food source in agrarian societies. Over time, its meaning expanded to encompass specific aromatic herbs and medicinal plants, most notably the bishopwort (Agastache rugosa).
