"枳壳粉末" can be translated as "Powder of Fructus Aurantii" in English.
Here, “枳壳” (Zhǐké) refers to the dried, unripe fruit of Citrus aurantium L. or its varieties, commonly used in traditional Chinese medicine. “粉末” (fěnmò) means "powder." In botanical or pharmacological contexts, the scientific or Latin name "Fructus Aurantii" is often used to precisely identify the medicinal material, with "Powder of" indicating its form as a powder.
