Examine products closely before purchase. Labels should have scientific names specifically. True black seed, Nigella sativa, is the scientific name. Don't accept labels just because they have common names. Trustworthy suppliers offer 3rd party testing. Speak with companies directly about plant sourcing.

Health outcomes of confusion really matter. Black cumin for respiratory ailments provides negligible results. Confusion causes surprising reactions. Different species can cause various allergic reactions. One patient developed a rash that had lost its identity. Correcting the identity prevented another rash.

Perform sensory verification testing yourself. With some seeds, crush them to release their aroma. Black seeds have a spicy aroma reminiscent of onions. Small black cumin produces a warm cumin aroma. Flavor will check for spicy and warm spice notes. If these quick tests are not conducted, mistakes can be costly.
