Si Wu Tang (四物湯)

In today's post, I will discuss a herbal soup called the Si Wu Tang (四物湯), that is very suitable for ladies after your mensuration. This is a herbal soup that is a must after mensuration in order to regulate and fortify your body. This herbal prescription is typical and well-known. Some of you lady readers out there might have experience your mother, grandmother telling you about this soup.

So, today I shall discuss the myth involving this soup. Who can drink it? When to drink it? Is this there any caution to be observed when taking this soup? i shall now start by presenting the ingredients of the Si Wu Tang (四物湯).

The ingredients of the prescription are as follow: -
1. Dang Gui (当归, 三钱)
2. Chuan Xiong (川芎, 二钱)
3. Bai Shao (白芍, 三钱)
4. Shou Di Huang (熟地黄, 四钱)

The primary role of the Si Wu Tang (四物湯) is to "nourishing liver blood". It is suitable for symptoms such as dizziness, blurred vision, hand, foot numbness, cramps, less menstrual flow, and others. In our modern world of living with the presence of living pressure, irregular lifestyle, coupled with poor eating habits (the love for deep-fried, spicy and barbecued stuff) results in us having a more dry and heaty (燥热) body structure. Thus, it makes us not really suitable for the consumption of the Si Wu Tang (四物湯). But, does that means that ladies out there could no longer consume it.

If you really need to consume it, you can arrange to go through checkup at the Chinese medicine practitioners, who will modified the Si Wu Tang (四物湯) according to each and individuals physical conditions.

Si Wu Tang (四物湯) is not a cure for any disease nor is it a miracle prescription for the ultimate regulation and fortification of your body. It is only in one of the many traditional Chinese medicine prescriptions, that have been used traditionally for the ladies after mensuration. So, before consuming, it is advisable and also a sensible thing to consult a qualified Chinese medicine practitioner for his/her advise.

It is an important to note. Medicine use in the correct and proper manner is to solve the problems and will be helpful to the body. In the opposite sense, if medication is taken in a disorder manner, the medication may become a "poison" to the body.

中药炮制的目的

中药炮制的目的是多方面的,往往炮制方法或者炮制一种药物,同时具有几方面的目的,有些虽有主次之分,但彼此之间又有密切的联系。

1. 有毒中药炮制均可降低毒性
  如川乌、半夏、马钱子等;有些毒性药物炮制除降低毒性外,还可缓和药性,如甘遂、芫花醋炙,巴豆制霜均可缓和泻下作用。

2. 有副作用的药物炮制均可消除或减弱副作用
  如柏子仁具有宁心安神、润肠通便等作用,生品服后产生滑肠致泻的作用,通过去油制霜炮制后即消除了致泻的副作用;瓜蒌仁制霜、马兜铃蜜炙可消除令人呕吐的副作用;厚朴姜炙、黄精蒸制可消除对咽喉的刺激性。

3. 改变药性
  生品、制品药性不同,临床应用各异。如蒲黄生用性滑,活血化瘀,炒炭后性涩,止血;生甘草性凉,清热解毒,蜜炙后性温,能补中益气;生地黄性寒,清热凉血,熟地黄性温,滋阴补血;何首乌生用。

4.药性峻烈的药物经炮制可缓和药性
  如麻黄生用辛散解表发汗作用较强,蜜制后辛散作用缓和,发汗力减弱,而止咳平喘作用增强;苍术、枳壳麸炒缓和燥性;槐花炒黄、黄连酒炙、大黄酒炙缓和苦寒之性;牛蒡子炒黄缓和寒滑之性等。

5. 增强药物疗效
  可通过炮制后改变药物质地,使其质地酥脆、易于粉碎、利于成分的煎出而提高疗效。如种子类药物炒黄;质地坚硬的矿物药、贝壳类煅制。还可借助辅料的作用增强疗效,如蜜炙款冬花、紫菀等,由于蜂蜜的协同作用,可增强其润肺止咳作用;羊脂炙淫羊藿可增强其治疗阳痿的效能;胆汁制南星能增强其镇惊作用。

6.改变或增强药物作用的部位和趋向
  通过炮制可引药入经,改变作用部位及趋向。如大黄酒炙能引药上行;柴胡、香附等经醋制后有助于引药入肝;小茴香、橘核等经盐制后,有助于引药入肾。

7.便于调剂和制剂
  矿物类、贝壳类及动物骨甲类药物,必须经过煅、煅淬、砂烫等,使其质地变为酥脆,易于粉碎及煎出有效成分。

8.有利于贮藏及保存药效
  药物经过干燥处理,使药物含水量降低,避免霉烂变质,有利于贮存。一些昆虫类、动物类药物经过热处理,如蒸、炒等能杀死虫卵,防止孵化,便于贮存,如桑螵蛸等。植物种子类药物经过蒸、炒、燀等的加热处理,能终止种子发芽,便于贮存而不变质,如苏子、莱菔子等。加热处理可杀酶保苷,如黄芩、杏仁等。

9. 矫味矫臭,利于服用
  动物类药物或其他有特殊臭味的药物,炮制后均能起到矫味矫臭的效果,如酒制乌梢蛇、紫河车、麸炒僵蚕、椿根皮,醋制乳香、没药,长流水漂洗人中白等。

10.提高药物净度,确保用药质量
  这是药物炮制的共同目的。如种子类药物要去沙土、杂质,根类药物要去芦头,皮类药物要去粗皮等。

中药炮制与临床疗效

中药必须经过炮制之后才能入药,是中医用药的特点之一。中药炮制是根据中医药理论,依照辩证施治用药的需要和药物自身性质,以及调剂、制剂的不同要求,所采取的制药技术。

中药炮制与临床疗效

1. 中药炮制是中医长期临床用药经验的总结。炮制工艺的确定应以临床需求为依据。炮制工艺是否合理、方法是否恰当,直接影响到临床疗效。中药的净制、切制、加热炮制与加辅料制均可影响临床疗效。

2. 加热是中药炮制的重要手段,其中炒制、煅制应用广泛。许多中药经炒制后,可杀酶保苷,如芥子,牛蒡子等;煅制常用于处理矿物药,动物甲壳及化石类药物,能使质脆易碎,而且作用也会发生变化。如白矾煅后燥湿、收敛作用增强。血余煅炭后能止血。川乌、草乌加热煮制后,其毒性显著降低,保证了临床用药安全有效。

3. 中药经辅料制后,在性味、功效、作用趋向归经和毒副作用方面都会发生某些变化,从而最大限度地发挥疗效。

炮制对药性的影响

1. 炮制对四气五味的影响
- 是通过“反制”纠正药物过偏之性,以缓和药性。如栀子姜汁制后,能降低苦寒之性,以免伤中;
- 是通过“从制”,使药物的性味增强,增强疗效。如胆汁制黄连,增强黄连苦寒之性,所谓寒者益寒;酒制仙茅,增强仙茅温肾壮阳作用,所谓热者益热;
- 是通过炮制,改变药性,扩大药物的用途。如天南星辛温,善于燥湿化痰,祛风止痉;加胆汁制成胆南星,则性味转为苦凉,具有清热化痰,熄风定惊的功效。

2. 炮制对升降浮沉的影响
药物经炮制后,可改变其作用趋向,如酒制引药上行,盐炙引药下行入肾经。

3. 炮制对归经的影响
中药炮制很多都是以归经理论作指导的,特别是用某些辅料炮制药物,如醋制入肝经,蜜制入脾经,盐制入肾经等。

4. 炮制对毒性的影响
去毒常用的炮制方法有净制、水泡漂、水飞、加热、加辅料处理、去油制霜等。具有毒性的中药经炮制均可降低毒性。
