Traditionally, dong quai is said to be one of the most important herbs for strengthening the xue . The Chinese term xue is often translated as "blood," but it actually refers to a complex concept in traditional Chinese medicine , of which the Western notion of blood is only a part. In the late 1800s, an extract of dong quai known as Eumenol became popular in Europe as a "female tonic," and this is how most people consider it in the West.

Taking dong quai is good for ladies especially after her monthly period.
Just boil with black dates and drink a cup before you sleep.
It's a very healthy drink.
