Black seed or Nigella sativa is variously referred to as black caraway, black cumin, black onion seed or kalonji. It is native to the Middle East and has been used for over 2000 years as a traditional remedy. Archaeologists also found it in the tomb of King Tut in Egypt (who lived about 3,300 years ago).
Both the raw seed or its oil extract have been found to be effective in treating several ailments either alone or in combination with other ingredients. The healing properties of black seed are due to the active ingredient thymoquinone which makes up between 30-48 percent of the black
seed oil. In addition to having several health benefits when used alone, it can also be used in combination with garlic extract for added synergistic effect.
The oil has to be processed and stored properly, otherwise it may become stale and smelly. It has to be
stored only in dark colored glass bottles.
