The invention discloses a production technology of down capable of tranquilizing and allaying excitement. The production technology comprises the following sequential steps of preliminary distribution, ash removal, fine distribution, rough cleaning, cleaning, rinsing, primary dehydration, immersion, secondary dehydration, and drying to form finished down, wherein in the rinsing step, cleaned semifinished down is put into boiling water for boiling for 10-15min, taken out, immersed with 10-15% of hydrogen peroxide for 5-10min, and rinsed cleanly with clear water, and in the immersion step, 1/4-1/5 of semifinished down subjected to dehydration treatment is put into 30-40 DEG C traditional Chinese medicine liquor and immersed for 4-6h. The traditional Chinese medicine liquor comprises the following raw materials by weight percentage: 8-12% of uncaria rhynchophylla, 13-17% of chrysanthemum, 13-17% of gastrodia elata, 6-10% of aster striatus, 8-12% of semen platycladi, 6-10 parts of marigold, and 13-17% of syzygium aromaticum, wherein the raw materials are put into the clear water for boiling for 20-30min, and then a filtrate is obtained. The traditional Chinese medicine liquor used in the production technology adopts traditional Chinese medicine capable of tranquilizing and allaying the excitement, the semifinished down subjected to the dehydration treatment is immersed in the traditional Chinese medicine liquor, and essence of the traditional Chinese medicine is immersed into a down body, so that the down can both keep warm and tranquilize and allay the excitement.
