枇杷叶、旋覆花、辛荑等含非腺毛类药材,在入汤剂煎煮时,从不完全的历史资料和现代的有关文献中了解,均记载“包煎”。显然包煎的目的在防止非腺毛脱落于汤液中,服后出现的呛咳。但是在包煎中,由于药料被包裹于包煮材料中 The non-glandular medicinal materials including loquat leaves, inula flowers, and cicadas are known in the incomplete historical data and modern related literature when they are decocted into decoction.
