Field Pennycress (Thlaspi arvense)

The seeds and leaves can be consumed either raw or boiled. It is advisable to boil them, though, as the
taste of the leaves can be a little bitter (it is also known as stinkweed). It proves to be a good source of
vitamins and minerals. Speaking of which, it is not recommended to eat it if it is growing near
contaminated soil because of its tendency to quickly absorb heavy metals--like lead. It can be used as a
diuretic, for rheumatism, to reduce fever (by the stimulation of sweating), and as an expectorant. It
should be eaten in small quantities and not regularly, as it can produce gastric problems and stimulate
abortion. Pennycress is being developed as an oilseed crop for biodiesel production. Its seed oil was
used in the past for lighting.
