An Introduction to the Benefits, Uses and Culinary Value of Emilia sonchifolia

Emilia sonchifolia is an annual or perennial herbaceous plant in the genus Emilia of the Asteraceae family, commonly known among the people as yang ti cao, hong bei ye, ye xia hong and other names. It is fairly common in southern China, growing mostly by field edges, roadsides, hillsides or on moist grassland. It gets the name "one dot of red" because the flower head it opens at the tip of its stem is purplish-red, looking from a distance like a little dot of red blush dabbed on the branch tip.

In appearance, this plant is usually not tall, with leaves mostly clustered on the lower part of the stem; the leaf surface is green while the underside often carries a purplish-red tint, which is an important feature for identifying it. Breaking the stem or leaves releases a small amount of white milky sap. The whole plant can be used medicinally, generally harvested in summer and autumn; after washing it can be used fresh, or dried in the sun and stored for later use.

In traditional medicine, Emilia sonchifolia is considered to have the effects of clearing heat and detoxifying, cooling the blood and reducing swelling. Among the people it is often used to address sore, swollen throat, cold with fever, enteritis and diarrhea, and some people pound the fresh leaves and apply them externally to deal with skin problems such as boils and swollen painful sores. It should be noted that these uses mostly come from folk experience; for actual medicinal use one should still follow a doctor's guidance and should not use it on one's own to replace proper treatment.

Besides its medicinal use, Emilia sonchifolia is also a common wild vegetable in some southern regions. After blanching the tender stems and leaves to remove some of the bitterness, they can be stir-fried, cooked in soup or served as a cold dressed dish; the taste carries a faint fresh fragrance, and it is a seasonal wild delicacy in many places during spring and summer. When picking it, choose an environment far from pollution and avoid field-edge stretches that have been sprayed with pesticides.

Overall, Emilia sonchifolia has many uses, but its nature and flavor are rather cold, so those with a weak, cold spleen and stomach as well as pregnant women had best consult a professional before eating or using it. When collecting it in the wild, also take care to distinguish it from plants of similar appearance to ensure food safety.
