This species has reputed medicinal value. Sium ninsi Thunberg (Fl. Jap. 118. 1784), known from Korea, Japan, and SE Russia, is likely to occur also in SE Heilongjiang and E Jilin. The upper part of the plant is morphologically similar to S. suave but can be distinguished by the long-petiolate, ternate uppermost cauline leaves (vs. sessile in S. suave).
