薏 rarely stands alone — it almost always appears in 薏米 (yìmǐ, 'Job's tears grain'), 薏仁 (yìrén), or the original literary 薏苡 (yìyǐ). The grain is a staple of traditional Chinese medicine, said to dispel dampness.

Note the 艹 (grass) radical on top — like 茶/草/苹, this signals a plant. The phonetic 意 (yì, 'meaning') gives the sound.
