Lepidium / Descurainia Seed tíng lì zǐ · 葶苈子

Safety. Forceful, and classically not used in weak or deficient people or continued long-term. Laboratory studies have reported cardiotonic activity; that is a laboratory finding, not an established clinical benefit, and it is a specific reason not to combine it with heart medicine — particularly digoxin-type drugs — without professional supervision. Its diuretic action has not been studied alongside prescription diuretics. Safety in pregnancy and breastfeeding is not established. Two different plants supply this name depending on region, so identity is not guaranteed by the label.
