This is not black caraway oil but it is black cumin oil. Which is a cure for all diseases as stated by our prophet mohammad. It is only toxic when taken in high, high doses. Many take the seeds, cook slightly to remove the hot flavor as will burn your stomach and then cool and put in blender and then add to honey or put in caps. It does retain water in the body so no ideal for someone wanting to loose weight.
I take the ground seeds and put 1/2 t. each day in my smoothie.
