Coriander is believed to be native to Iran (Persia). Seeds have been found in very old archaeological digs, dating back at least 3000 years. There were coriander seeds in the tomb of Tutankhamen.
There is abundant research on the use of coriander seed essential oil for serious liver conditions and cancer, but the traditional uses suroudigestive. For this purpose, it can be taken internally or mixed with a carrier oil and gently massaged into the abdominal area.
Coriander oil is both fungicidal and larvicidal. It is also antimicrobial. Research on coriander essential oil suggest that the oil inhibits gram-positive and gram-negative bacteria, including Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, and Escherichia coli.
Since oils also have psychospiritual actions, coriander is an oil to consider if one loses oneself to others or placates others at the expense of self and sovereignty. This is a solar plexus action. Just as coriander seed is good for digestion, it is good for standing up for oneself . . . in a warm and loving way.
The aroma has hints of citrus and does not at all resemble the leaf oil which is incredibly intense and cloying. The main oils found in coriander are linalool and pinene. The levels depend on the freshness of the fruit (seed). Coriander blends well with citrus oils, especially bergamot, and is safe for internal use.
