The production method of Tiantai black medicine

1. Pick up impurities, divide them into small and large strips, soak them in water, change the water according to the season to prevent odor, and promptly remove and slice them. If the slices have already been sliced fresh, sieve out the dust

2. Stir fry: Take clean black pills and stir fry over low heat until dark yellow, then remove

3. Gluten preparation: Take clean black pills, stir fry with wheat bran until slightly yellow, sieve off the wheat bran to obtain

4. Vinegar making: Mix the black pills with vinegar, cover slightly, and stir fry in a pot over low heat until slightly charred. Remove and let cool. For every 500 grams of black medicine, use 6 grams of vinegar

5. Wine making: Take black medicine pills, mix well with yellow wine, let it moisten until the wine is gone, stir fry in a pot over low heat until slightly dry, take out and let it dry. For every 500 grams of black medicine, use 60 grams of yellow wine

6. Salt making: Take wheat bran, stir fry it hot, add black medicine tablets moistened with salt water for half an hour, stir fry for 3-4 minutes until it turns light yellow, then sieve off the wheat bran. 16 kilograms of black medicine, 0.4 kilograms of salt, 2 kilograms of boiling water, and 2 kilograms of wheat bran

1. Identification of characteristics: The roots of black medicine are spindle shaped or round, slightly curved, and some have a central contraction in a continuous bead shape, commonly known as "black medicine beads", with a length of 5-15cm and a diameter of 1-3cm. The surface is yellow brown or gray brown, with fine longitudinal wrinkles and sparse fine root marks. Extremely hard in texture, not easily broken, with a yellow white cross-section.
