莱菔子为十字花科植物萝卜Raphanus sativus L.的成熟种子。全国各地均有栽培。夏季果实成熟时采割植株,晒干,搓出种子,除去杂质,再晒干。生用或炒用,用时捣碎。

【药性】辛、甘,平。归肺、脾、胃经。        【功效】消食除胀,降气化痰。       
 
【应用】        1.食积气滞证。本品味辛行散,消食化积之中,尤善行气消胀。常与山楂、神曲、陈皮同用,治食积气滞所致的脘腹胀满或疼痛,嗳气吞酸,如保和丸(《丹溪心法》);若再配白术,可攻补兼施,治疗食积气滞兼脾虚者,如大安丸(《丹溪心法》)。       
 
2.咳喘痰多,胸闷食少。本品既能消食化积,又能降气化痰,止咳平喘。尤宜治咳喘痰壅,胸闷兼食积者,如《食医心镜》单用本品为未服;或与白芥子、苏子等同用,如三子养亲汤(《韩氏医通》)。       
 
 此外,古方中有单用生品研服以涌吐风痰者,但现代临床很少用。       
 
【用法用量】煎服,6~10g。生用吐风痰,炒用消食下气化痰。       
 
【使用注意】本品辛散耗气,故气虚及无食积、痰滞者慎用。不宜与人参同用。       
 
【鉴别用药】莱菔子、山楂均有良好的消食化积之功,主治食积证。但山楂长于消积化滞,主治肉食积滞;而莱菔子尤善消食行气消胀,主治食积气滞证。       
 
【古籍摘要】        1.《日华子本草》:“水研服吐风痰,醋研消肿毒。”      
 
  2.《本草纲目》:“下气定喘,治痰,消食,除胀,利大小便,止气痛,下痢后重,发疮疹。”       
 
3.《医林纂要》:“生用,吐风痰,宽胸膈,托疮疹;熟用,下气消痰,攻坚积,疗后重。”       
 
【现代研究】        1.化学成分:莱菔子含莱菔素、芥子碱、脂肪油(油中含大量芥酸、亚油酸、亚麻酸)、β-谷甾醇、糖类及多种氨机酸、维生素等。      
 
  2.药理作用:莱菔子提取液,实验有缓和而持续的降压作用,且效果稳定,重复性强,亦无明显毒副作用;其注射液的降压作用,与药物浓度有关。莱菔子能增强离体兔回肠节律性收缩和抑制小鼠胃排空。在体外对多种革兰氏阳性菌和阴性菌均有较强的抗菌活性;莱菔素1mg/ml浓度能显著抑制葡萄球菌和大肠杆菌;其水浸剂(1∶3)在试管内对同心性毛癣菌等6种皮肤真菌有不同程度的抑制作用。莱菔子还有抗菌、祛痰、镇咳、平喘、改善排尿功能及降低胆固醇,防止动脉硬化等作用。莱菔子于体外能中和破伤风毒素与白喉毒素。     
 
   3.临床研究:据报道,用莱菔子或经适当配伍可用于治疗小儿久咳、小儿顽固性哮喘、厌食症、婴幼儿腹泻等多种疾病,疗效满意。近年临床还报道:将莱菔子制成浸膏液服用,治疗高血压病 120例,有效率90%(中西医结合杂志,1986,2∶110); 用炒莱菔子研末,每次20~30g,加醋调敷神阙穴,治疗小儿疳积 32例,有效率98.6%(山东中医杂志,1997,3∶139);用于治疗膝关节创伤性滑膜炎,以莱菔子50g,捣碎后加醋25ml调糊摊纱布上外敷患处,隔日换药1次,治疗80例,有效率98.3%(中医正骨,1990,4∶46)。此外,又可用治老年性便秘、崩漏、急性肠梗阻、湿疹等多种病证。       
 
4.不良反应:莱菔子毒性较小。但莱菔素静注100mg,可引起小鼠死亡。前人认为人参不宜与莱菔子同用,恐其消减人参补虚之功,但服人参而引起脘腹胀满时,服莱菔子则能使之缓解。实验研究表明,人参与莱菔子同服,对人参提高小鼠抗疲劳、耐缺氧及抗应激等功效亦未见影响(中医杂志,1996,5∶300)。
