辨證分析及方解:
此病發(fa)于霜降后(hou),天氣(qi)(qi)驟冷,患者(zhe)正氣(qi)(qi)不(bu)足,皮毛汗孔開(kai)合失司,予風寒(han)之(zhi)邪所乘,榮衛俱傷(shang),加之(zhi)時值秋燥當令,大氣(qi)(qi)下降,燥氣(qi)(qi)早伏,今又外(wai)感表郁,陽(yang)氣(qi)(qi)不(bu)得外(wai)達(da)。表郁而內(nei)熱,營衛不(bu)合,故患者(zhe)既現惡寒(han)發(fa)熱,遇風受冷則(ze)疹出(chu)之(zhi)證,又有(you)煩躁口(kou)干之(zhi)候。
治應以調(diao)(diao)(diao)和(he)(he)營(ying)衛為(wei)(wei)主,故以桂(gui)枝(zhi)(zhi)湯為(wei)(wei)主方(fang)。桂(gui)枝(zhi)(zhi)辛溫通陽,溫經(jing)散寒(han);白芍酸(suan)苦微寒(han),斂陰(yin)和(he)(he)營(ying),二者相(xiang)合一散一斂調(diao)(diao)(diao)和(he)(he)營(ying)衛;患者體弱,納差食少,又有脾胃(wei)虛弱之象,炙草、生姜、大(da)棗大(da)補中氣,內外兼調(diao)(diao)(diao),中氣復,榮衛和(he)(he),患者無汗(han)惡(e)寒(han),故少加(jia)(jia)麻黃(huang),與桂(gui)枝(zhi)(zhi)相(xiang)合小發其(qi)(qi)汗(han),祛邪外出(chu);又病煩躁口干,故加(jia)(jia)石膏清其(qi)(qi)內熱(re),方(fang)中姜棗量大(da),又囑其(qi)(qi)服熱(re)稀粥(zhou),防其(qi)(qi)寒(han)涼敗(bai)胃(wei)。成方(fang)即(ji)為(wei)(wei)桂(gui)枝(zhi)(zhi)二越婢一湯,唯用量隨證之寒(han)熱(re)而加(jia)(jia)減(jian)矣。
體會
對于蕁(qian)麻(ma)(ma)疹,中(zhong)醫認(ren)為是(shi)(shi)(shi)血(xue)中(zhong)有(you)(you)熱,血(xue)熱生風(feng)所致(zhi)(zhi)(zhi),“祛風(feng)先(xian)活血(xue),血(xue)行(xing)風(feng)自(zi)滅”,大都(dou)采(cai)用(yong)清(qing)熱涼(liang)血(xue),活血(xue)祛風(feng)方藥(yao)(yao)治(zhi)(zhi)(zhi)(zhi)療(liao)。以此理論(lun)指導下對該病(bing)(bing)人(ren)(ren)(ren)進行(xing)辨證(zheng)施(shi)治(zhi)(zhi)(zhi)(zhi),在治(zhi)(zhi)(zhi)(zhi)療(liao)無效,且病(bing)(bing)人(ren)(ren)(ren)并現(xian)嘔(ou)吐(tu)后(hou)(hou),帶(dai)(dai)教老(lao)(lao)師(shi)想(xiang)放棄中(zhong)醫治(zhi)(zhi)(zhi)(zhi)療(liao),改用(yong)西藥(yao)(yao)掛水的情(qing)形(xing)下,余等再三揣摩,提出(chu)試用(yong)桂麻(ma)(ma)各半(ban)湯(tang)(tang)治(zhi)(zhi)(zhi)(zhi)療(liao)。《傷寒(han)論(lun)》麻(ma)(ma)桂合(he)劑(ji)一般作為解表(biao)使用(yong),治(zhi)(zhi)(zhi)(zhi)療(liao)“表(biao)郁輕證(zheng)”。本例(li)蕁(qian)麻(ma)(ma)疹病(bing)(bing)人(ren)(ren)(ren)沒(mei)有(you)(you)惡寒(han)發熱之(zhi)象,之(zhi)所以選用(yong)其治(zhi)(zhi)(zhi)(zhi)療(liao),一是(shi)(shi)(shi)病(bing)(bing)因相同,是(shi)(shi)(shi)受(shou)風(feng)寒(han)所致(zhi)(zhi)(zhi),二是(shi)(shi)(shi)病(bing)(bing)人(ren)(ren)(ren)皮膚瘙癢(yang),與(yu)桂麻(ma)(ma)各半(ban)湯(tang)(tang)證(zheng)之(zhi)“身(shen)癢(yang)”一致(zhi)(zhi)(zhi),三是(shi)(shi)(shi)皮疹色紅與(yu)原湯(tang)(tang)證(zheng)中(zhong)“面赤”相仿。由于病(bing)(bing)人(ren)(ren)(ren)有(you)(you)內熱煩躁,征(zheng)求趙老(lao)(lao)師(shi)意見而最終改用(yong)桂枝二越婢(bi)一湯(tang)(tang)。成方之(zhi)后(hou)(hou)請臨床(chuang)帶(dai)(dai)教老(lao)(lao)師(shi)簽(qian)字(zi)。老(lao)(lao)師(shi)看(kan)后(hou)(hou)問這是(shi)(shi)(shi)何(he)方,答“桂枝二越婢(bi)一湯(tang)(tang)”,老(lao)(lao)師(shi)聽后(hou)(hou)搖(yao)了搖(yao)頭,似覺用(yong)藥(yao)(yao)太(tai)少,又非猛劑(ji),如(ru)何(he)能(neng)(neng)治(zhi)(zhi)(zhi)(zhi)這怪病(bing)(bing),最終卻還是(shi)(shi)(shi)簽(qian)了字(zi),也(ye)許是(shi)(shi)(shi)覺得此方雖不(bu)能(neng)(neng)治(zhi)(zhi)(zhi)(zhi)病(bing)(bing)卻也(ye)不(bu)致(zhi)(zhi)(zhi)吃壞吧(ba)!莫說老(lao)(lao)師(shi),就是(shi)(shi)(shi)余等雖知辨證(zheng)準確,但(dan)見此方如(ru)此“單薄”,一共(gong)5味藥(yao)(yao)(姜棗(zao)自(zi)備)而已,心中(zhong)也(ye)著實(shi)沒(mei)底。直到病(bing)(bing)人(ren)(ren)(ren)吃完頭3副藥(yao)(yao)后(hou)(hou)病(bing)(bing)情(qing)好轉(zhuan),才敢放膽(dan)加量。
人(ren)說中醫(yi)見效慢(man),《傷(shang)寒論(lun)》已(yi)過(guo)時,余(yu)等(deng)以親(qin)眼所見推翻此(ci)等(deng)謬論(lun)。此(ci)方療(liao)效如此(ci)之好,讓余(yu)等(deng)對中醫(yi)充滿(man)信心,對《傷(shang)寒論(lun)》興趣十足。經(jing)方制方嚴謹,配伍精妙,對經(jing)方的(de)學習有助(zhu)于(yu)初涉臨床的(de)醫(yi)學生增加自(zi)信心,提高辨證論(lun)治能(neng)力,培養(yang)良好的(de)用藥習慣,有百利而無一(yi)害。《傷(shang)寒論(lun)》(不管她淪為(wei)選修課(ke))魅力極大,奉勸各位在(zai)校(xiao)生苦讀(du),實習工作(zuo)時自(zi)能(neng)體會(hui)其(qi)妙處!
