Di San Xian is a simple home-cooked dish composed of three kinds of seasonal vegetables. Although the name looks tall, it is not difficult to make. In China's home cooking culture, Di San Xian is a dish that widely exists on every family table, but do you know the origin of the name Di San Xian?

In ancient China, people had the saying of "tasting three flavors" in the long summer. There are three kinds of sanxian: the earth sanxian, the tree sanxian and the water sanxian. We are familiar with the fresh vegetables in the field: amaranth, wheat and broad beans.

Later, in the northeast, three of the three delicacies became potatoes, eggplant and peppers. These three dishes are fried together and taste better, so this dish has become an out-and-out famous dish in Northeast China.

One of the three great foods: potatoes.

Potato is a kind of food containing geothermal energy, vitamins and trace elements. It is not only an ideal diet food, but also can treat constipation, stomachache, dyspepsia, skin eczema and other diseases. It is a high-quality health food for patients with stomach diseases and heart diseases.

The second of the three delicacies: eggplant

Eggplant skin is rich in vitamin E and vitamin P, which is unmatched by any other vegetable. Vitamin P can soften microvessels, prevent microvascular bleeding, and play a good auxiliary role in the treatment of hypertension, arteriosclerosis, hemoptysis and other diseases. Vitamin C and liquiritin in eggplant after sweating can lower cholesterol.

Three fresh: green pepper

Green peppers contain much more vitamin C than tomatoes. Spicy capsaicin can enhance appetite and promote digestion. Pepper is also rich in vitamin K, which can prevent and treat scurvy, and has an auxiliary treatment effect on gingival bleeding, anemia and vascular fragility.

Therefore, Rehmannia glutinosa is not only delicious, but also rich in nutritional value.
