The word Saffron, originates from the Arabic word Zafaran, which means yellow. The Saffron Crocus plant was initially cultivated by Minoans of ancient Crete. Saffron is the most expensive spice in the world, and requires 200,000 flowers (hand-picked) to produce 1 kg of Saffron.
Saffron is a bitter-sweet herb that aids digestion, stimulates circulation, and lowers high blood pressure. The Chinese use saffron as a medication to revitalize ‘stagnant liver energy’. Ayurveda uses the herb to strengthen the functioning of the stomach and to cure digestive problems. It is also used in treating cough, bloated stomach and colic.
During the ancient days, saffron was also used as an aphrodisiac, to increase flow of bile, to improve appetite and to deal with menopausal problems.
Apart from treating physical illness alone, saffron is also said to be beneficial in reducing depression. A study, published in the Journal of Ethnopharmacology, stated that saffron works just in the same manner as the modern day anti-depressants. It also enhances the activity of mood-boosting medications.
Another interesting fact is that, a research revealed that saffron inhibits carcinogenesis, and is now being studied as the most-effective Cancer Chemo-preventive agent.
However, it should be noted that Saffron contains a toxin that could cause kidney or nerve damage, when used in excess, and hence should be avoided by pregnant women.

One day in a Thai shopping mall near the place where I live I ate Thai KAOSOI yellow chicken soup with yellow noodle and green bean spout.After 20 min approx I felt a bit dizzyand very relaxed.I suffer fronm hypertension and suddenly i felt that the blood pressure dropped.I tried to repeat the same thing several time and investigated the reason for the yellow color of the soup and why is the blood pressure dropping without westeren medication.By the way the soup has a very good flavor to my liking and has also mixed in coconut milk.In thai language the yellow herb added to the soup or rice is called KAMIN or in English Safron.I searched on the net about Safron and found the answers to my questions.Best Regards to this site from David
