Embodiment 1
[0031] (1) Gather fresh Echinacea purpurea root and rhizome 50g, and clean it;
[0032] (2) Set up steam equipment, add appropriate amount of water (the water is about 5cm high) in an ordinary iron pot (diameter 18cm, height 20cm), set up a steaming grid at a distance of 5cm from the water surface and spread gauze, and cover the pot . Put the pot on the electric stove to heat, and insert the thermometer through the small hole of the pot cover, and the thermometer does not touch the water surface. If there is a gap, it can be sealed with wet gauze. The same effect can also be achieved by using a water bath, and it is more convenient.
[0033] (3) When the steam temperature rises to 98-99°C, wait for about 3 minutes. Spread the echinacea material evenly into the steamer in the pot, seal it, and steam it for 15 minutes;
[0034] (4) Take out the medicinal materials, and place the materials in a cool and dry environment to dry for 7 days;
[0035] (5) Collect and arrange the ...
Embodiment 2
[0038] (1) Gather fresh Echinacea purpurea root and rhizome 100g, and clean it;
[0039] (2) Set up steam equipment, add appropriate amount of water (the water is about 5cm high) in an ordinary iron pot (20cm in diameter, 20cm in height), set up a steaming grid at a distance of 5cm from the water surface and spread gauze, and cover the pot . Put the pot on the electric stove to heat, and insert the thermometer through the small hole of the pot cover, and the thermometer does not touch the water surface. If there is a gap, it can be sealed with wet gauze. The same effect can also be achieved by using a water bath, and it is more convenient.
[0040] (3) When the steam temperature rises to close to 100°C (about 98°C-99°C), wait for about 3-5 minutes. Spread the echinacea material evenly into the steamer in the pot, seal it, and steam it for 15 minutes;
[0041] (4) Take out the medicinal materials, and place the materials in a cool and dry environment to dry for 5 days;

Embodiment 3
[0044] Embodiment 3 Comparative Test 1
[0045] Harvest 100g of fresh Echinacea purpurea roots and rhizomes of two kinds of growth years respectively. After cleaning, divide each material into two parts with equal quality at random, each with an average of 50g. Each part of the material is steam treated with the method of the present invention (100° C. steam, 15 min), and then dried in the air, and the other two parts are then directly dried. The comparison results of the content of cichoric acid are shown in Table 1.
