Is processed Aconite root the same as Black Shun slice?

Under normal circumstances, processed Aconiti Lateralis Radix (Zhi Fuzi) is not entirely equivalent to Black顺片 (Black Shunpian). After processing methods such as salting, water-soaking, boiling, and stir-frying, the alkaloid content of raw Aconiti Radix (Sheng Fuzi) is reduced, thereby decreasing its toxicity and producing processed Aconiti Lateralis Radix (Zhi Fuzi). There are various processed forms of Zhi Fuzi, including Black顺片 (Black Shunpian), White附片 (White Fupian), Salt附子 (Salt Fuzi), and others. Therefore, Black Shunpian is only one type of processed Zhi Fuzi and cannot be considered completely equivalent to Zhi Fuzi as a whole.
