炭藥(yao)(yao)(yao)止血,是(shi)中(zhong)醫藥(yao)(yao)(yao)治療血液病的特色(se)之一(yi)。夏老(lao)臨證時亦善用(yong)炭藥(yao)(yao)(yao)止血,體會如下(xia)。
1.止血用炭藥,存性須掌握
炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)藥(yao)有炒炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)與煅炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)之別(bie)。所謂(wei)炒炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan),是指(zhi)將藥(yao)物(wu)置炒制容器(qi)內(nei),用武(wu)火或中火加(jia)熱,炒至外表焦黑色(又(you)稱炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)黑色),內(nei)部(bu)棕(zong)褐色或深褐色(又(you)稱老黃(huang)色)為度。這(zhe)樣就使藥(yao)物(wu)一半(ban)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)化(hua),不能灰化(hua);另(ling)一半(ban)存性,而(er)且能嘗出藥(yao)物(wu)固有的(de)(de)(de)氣味。花、葉、草(cao)等炒炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)后仍(reng)可清晰辨別(bie)藥(yao)物(wu)原形,如生地炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、地榆炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、槐角炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、荊(jing)(jing)芥(jie)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)等。所謂(wei)煅炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan),系指(zhi)將藥(yao)物(wu)直接放于(yu)無煙爐或適當的(de)(de)(de)耐火容器(qi)內(nei)燃燒,煅至炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)化(hua),防止(zhi)(zhi)灰化(hua),如血(xue)(xue)(xue)(xue)余炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、棕(zong)櫚炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、荷葉炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)等。臨床(chuang)常(chang)用于(yu)止(zhi)(zhi)血(xue)(xue)(xue)(xue)的(de)(de)(de)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)藥(yao)有涼血(xue)(xue)(xue)(xue)止(zhi)(zhi)血(xue)(xue)(xue)(xue)的(de)(de)(de)地榆炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、槐角炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、茅根炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、大薊炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan);收斂血(xue)(xue)(xue)(xue)的(de)(de)(de)棕(zong)櫚炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、側柏炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、藕節炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan);化(hua)瘀止(zhi)(zhi)血(xue)(xue)(xue)(xue)的(de)(de)(de)蒲黃(huang)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、茜(qian)根炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、血(xue)(xue)(xue)(xue)余炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan);溫經止(zhi)(zhi)血(xue)(xue)(xue)(xue)的(de)(de)(de)艾葉炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、炮姜(jiang)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan);清熱涼血(xue)(xue)(xue)(xue)的(de)(de)(de)生地炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、丹皮炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、梔子(zi)(zi)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、黃(huang)芩炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、金(jin)銀(yin)花炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan);祛風止(zhi)(zhi)血(xue)(xue)(xue)(xue)的(de)(de)(de)荊(jing)(jing)芥(jie)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、防風炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan);理(li)氣止(zhi)(zhi)血(xue)(xue)(xue)(xue)的(de)(de)(de)枳殼炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、橘皮炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan);澀腸止(zhi)(zhi)血(xue)(xue)(xue)(xue)的(de)(de)(de)烏梅炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、訶(he)子(zi)(zi)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan);補(bu)血(xue)(xue)(xue)(xue)止(zhi)(zhi)血(xue)(xue)(xue)(xue)的(de)(de)(de)熟地炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)、當歸(gui)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)以(yi)及瀉火化(hua)瘀的(de)(de)(de)大黃(huang)炭(tan)(tan)(tan)(tan)(tan)(tan)(tan)(tan)等。

2.用藥不在多,方法宜靈活
盡管目前臨床常(chang)用(yong)(yong)(yong)于(yu)(yu)(yu)止(zhi)(zhi)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)的(de)(de)(de)炭(tan)藥(yao)(yao)(yao)只有(you)20余(yu)種,但其用(yong)(yong)(yong)途確比(bi)較(jiao)(jiao)(jiao)廣泛(fan),用(yong)(yong)(yong)法(fa)也(ye)非常(chang)靈活。既用(yong)(yong)(yong)于(yu)(yu)(yu)各種血(xue)(xue)(xue)(xue)(xue)(xue)(xue)液病(bing)(bing)(bing)引起的(de)(de)(de)出血(xue)(xue)(xue)(xue)(xue)(xue)(xue),又(you)(you)用(yong)(yong)(yong)于(yu)(yu)(yu)其他疾(ji)病(bing)(bing)(bing)并發的(de)(de)(de)出血(xue)(xue)(xue)(xue)(xue)(xue)(xue),既可(ke)入煎劑,又(you)(you)可(ke)入丸、散之(zhi)(zhi)劑;既能口服(fu)(fu),又(you)(you)能外(wai)(wai)用(yong)(yong)(yong)。如(ru)近代(dai)名醫鄧(deng)鐵濤治(zhi)療(liao)崩漏的(de)(de)(de)“一(yi)味血(xue)(xue)(xue)(xue)(xue)(xue)(xue)余(yu)炭(tan)”等,又(you)(you)如(ru)柳學株治(zhi)療(liao)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)友(you)病(bing)(bing)(bing)的(de)(de)(de)“二(er)炭(tan)一(yi)粉”(生(sheng)地炭(tan)、茅根炭(tan)、 三七(qi)粉)等。筆(bi)者(zhe)體會,炭(tan)藥(yao)(yao)(yao)用(yong)(yong)(yong)于(yu)(yu)(yu)外(wai)(wai)治(zhi)時(shi),一(yi)般以單用(yong)(yong)(yong)為(wei)(wei)主(zhu),內服(fu)(fu)時(shi)既可(ke)單用(yong)(yong)(yong),又(you)(you)可(ke)合用(yong)(yong)(yong),然而應用(yong)(yong)(yong)最多(duo)(duo)的(de)(de)(de)是1~2味或數味炭(tan)藥(yao)(yao)(yao)與(yu)其他藥(yao)(yao)(yao)物配(pei)合,組(zu)為(wei)(wei)復方應用(yong)(yong)(yong)。例如(ru)涼(liang)(liang)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)止(zhi)(zhi)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)藥(yao)(yao)(yao),通(tong)常(chang)生(sheng)品涼(liang)(liang)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)力勝,炒炭(tan)后則止(zhi)(zhi)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)作用(yong)(yong)(yong)強,具體運用(yong)(yong)(yong)時(shi)若(ruo)病(bing)(bing)(bing)人血(xue)(xue)(xue)(xue)(xue)(xue)(xue)熱較(jiao)(jiao)(jiao)盛,且方中(zhong)(zhong)已有(you)足夠的(de)(de)(de)涼(liang)(liang)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)止(zhi)(zhi)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)藥(yao)(yao)(yao)時(shi),選(xuan)加部分炭(tan)藥(yao)(yao)(yao)可(ke)增強止(zhi)(zhi)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)同澀作用(yong)(yong)(yong);反之(zhi)(zhi),若(ruo)病(bing)(bing)(bing)人出血(xue)(xue)(xue)(xue)(xue)(xue)(xue)量較(jiao)(jiao)(jiao)多(duo)(duo),血(xue)(xue)(xue)(xue)(xue)(xue)(xue)熱又(you)(you)不(bu)太盛,但方中(zhong)(zhong)已有(you)足夠的(de)(de)(de)止(zhi)(zhi)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)炭(tan)藥(yao)(yao)(yao)時(shi),選(xuan)加部分生(sheng)藥(yao)(yao)(yao)以增強清熱涼(liang)(liang)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)之(zhi)(zhi)功。可(ke)見,炭(tan)藥(yao)(yao)(yao)止(zhi)(zhi)血(xue)(xue)(xue)(xue)(xue)(xue)(xue),不(bu)在于(yu)(yu)(yu)多(duo)(duo),而在于(yu)(yu)(yu)精;方法(fa)靈活,貴(gui)在變通(tong)。亦正如(ru)明代(dai)張介賓《景岳全書》所云:“治(zhi)血(xue)(xue)(xue)(xue)(xue)(xue)(xue)之(zhi)(zhi)藥(yao)(yao)(yao),凡為(wei)(wei)君為(wei)(wei)臣,或宜專用(yong)(yong)(yong),或宜相兼(jian),病(bing)(bing)(bing)有(you)深淺,方有(you)輕(qing)重,其間參合之(zhi)(zhi)妙固由乎人,而性(xing)用(yong)(yong)(yong)之(zhi)(zhi)殊知其矣。”可(ke)謂一(yi)言(yan)中(zhong)(zhong)的(de)(de)(de)。
