Is processed Aconitum carmichaelii (Zicao Wu) the same as Heishunpian?
Generally speaking, processed Aconite Root (Zhi Cao Wu) is not Black Prepared S附ce (Hei Shun Pian). The detailed explanation is as follows:

Processed Aconite Root is derived from the dried mother root of the Aconitum plant (Ranunculaceae family), after processing. Black Prepared Slice, on the other hand, is a processed product made from the daughter roots of the same species. It is typically prepared by boiling the daughter roots until appropriately done, then slicing and drying them either under the sun or by heating, resulting in a black surface color. As these two herbs come from different sources, they are not the same kind of Chinese herb.
Processed Aconite Root is warm in nature, with a pungent and bitter taste, and enters the Heart, Liver, Kidney, and Spleen meridians. It functions to dispel wind and dampness, warm the channels, and relieve pain. It is commonly used for conditions such as cold-damp bi syndrome, joint pain, and cold pain in the chest and abdomen. Black Prepared Slice is very hot in nature, with a pungent and sweet taste, and enters the Heart, Kidney, and Spleen meridians. It has effects of restoring yang to rescue from collapse and supplementing fire to assist yang, and is mainly used for conditions such as loss of yang with collapse and detachment, cold limbs and weak pulse, and insufficient heart yang. In clinical practice, the appropriate herb should be selected based on the patient's specific condition and under the guidance of a physician.
When taking traditional Chinese medicine, it is recommended to avoid consuming raw, cold, greasy, or spicy foods such as sushi, fried foods, chili peppers, etc., to prevent interference with the medicine's effectiveness.
