滑胎之法，惟欲其坐草之期易而且速。而难易之由，则在血之盈虚，不在药之滑利。盖血多则润而产必易，
血亏则涩而产必难。故未产之前，但当培养气血而预为之地，如四物汤、滑胎煎、五福饮、小营煎、八珍汤即
皆滑胎之要药。若不知此，而过用滑利等药，或产期未近，无火无滞而妄用清火行气之剂，多致血亏气陷，反
为临期大害。若果肥盛气实者，则紫苏饮，保生无忧散皆可择用。

The method for treating habitual abortion (Hua Tai) aims solely at facilitating a smooth and rapid delivery. The difficulty or ease of delivery depends on the fullness or deficiency of blood and Qi, not on whether the medicines possess lubricating properties. When blood is abundant, it provides moisture, making childbirth easy; when blood is deficient, there is dryness, making childbirth difficult. Therefore, before delivery, one should only nourish and cultivate blood and Qi in advance. Formulas such as Siwu Tang (Four Substances Decoction), Huatai Jian (Abortion-Preventing Decoction), Wufu Yin (Five Blessings Drink), Xiaoying Jian (Small Camp Decoction), and Bazhen Tang (Eight Treasures Decoction) are all essential formulas for ensuring safe delivery. If this principle is ignored and lubricating medicines are overused, or if cooling-fire and moving-Qi preparations are recklessly administered when the delivery date is not near and there is no fire stagnation, it often leads to blood deficiency and Qi sinking, which becomes a major hazard during labor. However, for individuals who are indeed obese with robust Qi, Zisu Yin (Perilla Leaf Drink) and Baosheng Wuyou San (Baosheng Wuyou Powder) can be selectively used.
