About
The character 蓖 is a phono-semantic compound created for botanical classification. Its upper component, the grass radical 艹, places it among herbaceous plants. The lower component, 毗, serves as the phonetic element. 蓖 refers exclusively to the castor-oil plant, a shrub with large leaves and toxic seeds that yield industrial and medicinal oil. It carries no independent meaning and appears almost solely in the compound term for the plant or its oil, making it a specialized term in agricultural and pharmacological contexts.
