Is it necessary to boil Heishunpian (Black顺片) before using it in medicine?

Black Prepared Slices (Hei Shun Pian) are usually required to be decocted first when used in herbal medicine. It is recommended to use the herb properly under the guidance of a physician.

When Black Prepared Slices are combined with other medicinal ingredients, if some of the herbs are particularly hard in texture and their active components are difficult to extract, or require prolonged decoction to fully exert their therapeutic effects, the Black Prepared Slices might also be required to be decocted first. The purpose of initial decoction is to ensure that the effective components of all the herbs are adequately released, thereby enhancing the overall efficacy of the herbal formula. To better integrate the medicinal properties, pre-decoction of the Black Prepared Slices might be recommended.

Generally, it is recommended to pre-decoct the Black Prepared Slices for 30 to 60 minutes. This time frame can be adjusted according to the specific herbal formula and the patient's condition, but it is essential to ensure thorough decoction of the Black Prepared Slices. During the decoction process, a high heat can initially be used to bring the herbal liquid to a boil, followed by a slow simmer. This method ensures sufficient dissolution of the active components in the Black Prepared Slices while preventing rapid evaporation of the liquid.

While taking Black Prepared Slices, patients should avoid consuming spicy and stimulating foods such as chili peppers and Sichuan peppercorns, as these may interfere with the effectiveness of the medication.
