血竭为一种较贵重的常用中药，始载于唐本草。原名麒麟竭，《本草纲目》释名血竭。李时珍在其《本草纳目》中称“‘麒麟竭’是树脂，……血竭树略如没药树……。采法亦于树下掘坎，斧伐其树，脂流于坎，旬日取之。”但据《中药志》记载及外商提供的情况，血竭是由棕榈科植物麒? Dragon’s Blood is a more expensive and commonly used traditional Chinese medicine, which was originally contained in Tang herb. The original name was Kirin exhaust, and the “Compendium of Materia Medica” was named after Dr. Li Shizhen said in his book “Ben Cao Mu” that “’Jinlin Deficiency’ is a resin, ... blood-drunken trees are as if there are no medicine trees .... The method of mining is also digging a tree under the tree, cutting its tree with axe, and the fat is flowing through the ridge.” Take it on a day-to-day basis.” But according to records in the “Chinese Medicine Chronicles” and information provided by foreign companies, Dragon’s Blood is derived from palm plants.
