4. Harvesting and processing
From late June to early August, after removing the mother roots, fibrous roots, and sediment, it is commonly known as "mud aconite" and processed into the following specifications: (1) Select a large and uniform mud aconite, wash it, immerse it in a solution of edible gall bladder water overnight, and then add salt. Continue soaking, take it out and dry it daily, gradually extending the drying time until a large number of crystalline salt particles (salt frost) appear on the surface of the aconite and the body becomes hard, commonly known as "salt aconite". (2) Take mud aconite and wash it according to size. Soak it in an aqueous solution of edible gallbladder for several days, boil it with the soaking solution until it penetrates the heart, remove it, float it in water, cut it vertically into slices about 0.5 cm thick, soak it in water, dye the aconite into a strong brown color with a coloring solution, take it out, steam it until an oily surface and luster appear, dry it to half dry, then dry it in the sun or continue drying it, commonly known as "black smooth slices". (3) Select evenly sized mud aconite, wash it, immerse it in a water solution of edible gallbladder for several days, boil it with the soaking solution until it penetrates the heart, remove it, peel off the outer skin, cut it vertically into slices about 0.3 centimeters thick, soak it in water, take it out, steam it through, and dry it in the sun, commonly known as "white aconite slices".
