再不止，更加捣茅根汁，磨墨同服。（久不止而热者，固宜矣，若脾气下陷，血不归经者，不宜如此加法）
胶艾汤 治劳伤气血，冲任虚损，月水过多，淋沥不止，及妊娠调摄失宜，胎气不安，
或因损动下血并治。（自古调经每多用艾，所以暖下元也。如下元虚而血随气降者宜之。血热者，当不必也）

当归饮（即芩术四物汤）具有抑制阳气、辅助阴气，调理经脉的作用，适用于月经量过多且无其他兼证的情况。
药材：当归（微炒）、川芎、白芍药、熟地黄（酒蒸焙）、白术、黄芩（各一钱）。
以上药物切碎，加水煎煮后服用。如果久治不愈发展为血崩，加入阿胶（炒）、山栀子（炒）、地榆、荆芥、甘草；或者仍不止血，再加入捣碎的茅根汁和磨好的墨同服。（久治不愈且有热象者，固然是适宜的，但如果是脾气下陷、血液不能归经者，则不宜这样加减用药。）
胶艾汤 治疗因劳损伤及气血，导致冲任二脉虚损，出现月经量多、淋漓不尽，以及妊娠期间调养失当、胎气不安，或因损伤导致的下部出血等症。（自古以来调经常多用艾叶，以此温暖下元。如下元虚寒而血液随气下降者适宜使用。若属血热者，则不必使用。）
药材：熟地黄、白芍药（各一钱）、当归、艾叶（各七分半）、阿胶（炒至成珠状）、川芎、甘草（炙，各五分）。
以上药物切碎，加水煎煮后服用。另一配方中加入地榆、黄芩。
丹溪方 治疗妇人先天禀赋虚弱，气不足以统摄血液，导致月经量多。（此方未用一味补血药，学者需领会此意。）
药材：白术（一钱半）、黄芪（生）、陈皮（各一钱）、人参（五分）、甘草（炙，二分）。
以上药物切碎，加水煎煮后服用。
七沸汤 治疗营卫虚弱，导致月经周期不准，或量多或量少，伴有腹痛。另一种说法认为，若是阴盛阳衰导致月经量少者，也可使用此方。（本方以血分药治疗月经周期不准，以气分药治疗腹痛，重点在于治疗腹痛，妙处在于各药分量相等，否则后三味药为何要使用呢？）
药材：当归、川芎、白芍药、熟地黄、蓬术、川姜、木香（各等分）。
每次服用四钱，加水一盏半，煎至八分，温服。
四物加葵花汤 治疗月经量少且排出不畅（涩少）。
药材：当归、川芎、白芍药、熟地黄、葵花（各二钱）。
另一配方又加入红花、血见愁。（此方全在血分调理，葵花须用红色的，因为它是润燥的药物。）
以上药物切碎，加水煎煮后服用。
四物汤加熟地黄当归汤 治疗月经量少且颜色调和正常。（妙在“色和”二字，尤其妙在增加了后两味药。）
药材：四物汤（四两），再加熟地黄、当归（各一两）。
每次服用一两，加水煎煮后服用。
Danggui Yin (Cinnamon Twig and Atractylodes Four Substances Decoction) suppresses Yang and assists Yin, regulating the meridians. It is indicated for excessive menstrual flow without other accompanying symptoms.
Herbs: Danggui (Radix Angelicae Sinensis, slightly stir-fried), Chuanxiong (Rhizoma Chuanxiong), Baishao (Radix Paeoniae Alba), Shudihuang (Radix Rehmanniae Praeparata, steamed with wine and baked), Baizhu (Rhizoma Atractylodis Macrocephalae), Huangqin (Radix Scutellariae, each 1 qian).
The above herbs are cut into small pieces, decocted in water, and taken orally. If the condition persists and develops into metrorrhagia (blood flooding), add Ejiao (Colla Corii Asini, fried), Shanzhizi (Fructus Gardeniae, fried), Diyü (Herba Siegesbeckiae), Jingjie (Herba Schizonepetae), and Gancao (Radix Glycyrrhizae); if bleeding still does not stop, add fresh juice of Mugeng (Herba Imperatae) ground together with ink. (For persistent bleeding with heat signs, this is appropriate; however, for cases due to Spleen Qi sinking and blood failing to remain within the vessels, such modifications are contraindicated.)
Jiao'ai Tang treats damage to Qi and Blood from overwork, deficiency and impairment of the Chong and Ren vessels, resulting in excessive menstrual flow and dripping continuously. It also treats improper care during pregnancy leading to unstable fetal Qi, or lower bleeding caused by trauma. (Since ancient times, Moxa leaf has been frequently used in regulating menstruation to warm the Lower Yuan. It is suitable for cases where Lower Yuan is deficient and blood descends with Qi. It is not necessary for cases of Heat in the Blood.)
Herbs: Shudihuang (Radix Rehmanniae Praeparata), Baishao (Radix Paeoniae Alba, each 1 qian), Danggui (Radix Angelicae Sinensis), Aiye (Folium Artemisiae Argyi, each 0.75 qian), Ejiao (Colla Corii Asini, fried until granular), Chuanxiong (Rhizoma Chuanxiong), Gancao (Radix Glycyrrhizae, honey-fried, each 0.5 qian).
The above herbs are cut into small pieces, decocted in water, and taken orally. Another prescription adds Diyü (Herba Siegesbeckiae) and Huangqin (Radix Scutellariae).
Danxi Formula treats women with weak congenital constitution and insufficient Qi to control blood, resulting in heavy menstruation. (This formula uses no single blood-tonifying herb; students should understand this principle.)
Herbs: Baizhu (Rhizoma Atractylodis Macrocephalae, 1.5 qian), Huangqi (Radix Astragali, raw), Chenpi (Pericarpium Citri Reticulatae, each 1 qian), Renshen (Radix Ginseng, 0.5 qian), Gancao (Radix Glycyrrhizae, honey-fried, 0.2 qian).
The above herbs are cut into small pieces, decocted in water, and taken orally.
Qifei Tang treats deficiency of Ying and Wei (Nutritive and Defensive Qi), causing irregular menstrual cycles with variable flow volume, accompanied by abdominal pain. Another view states it can be used for scanty menstruation due to Yin excess and Yang deficiency. (This formula uses blood-regulating herbs to treat irregular cycles and Qi-moving herbs to treat abdominal pain, focusing on the latter. The brilliance lies in equal proportions; otherwise, why use the last three herbs?)
Herbs: Danggui (Radix Angelicae Sinensis), Chuanxiong (Rhizoma Chuanxiong), Baishao (Radix Paeoniae Alba), Shudihuang (Radix Rehmanniae Praeparata), Pengzhu (Rhizoma Curcumae), Chuanjiang (Rhizoma Zingiberis Officinalis), Muxiang (Radix Aucklandiae, each equal parts).
Each dose is 4 qian, decocted in 1.5 cups of water until reduced to 0.8 cup, and taken warm.
Siwu Jia Kuihua Tang treats scanty and difficult menstrual flow.
Herbs: Danggui (Radix Angelicae Sinensis), Chuanxiong (Rhizoma Chuanxiong), Baishao (Radix Paeoniae Alba), Shudihuang (Radix Rehmanniae Praeparata), Kuihua (Flos Hibisci Rosa-Sinensis, each 2 qian).
Another prescription adds Honghua (Flos Carthami) and Xuejianchou (Herba Polygoni Avicularis). (This formula entirely regulates the Blood aspect; red Kuihua must be used as it moistens dryness.)
The above herbs are cut into small pieces, decocted in water, and taken orally.
Siwu Tang Plus Shudihuang and Danggui Tang treats scanty menstruation with normal color. (The brilliance lies in the term "normal color," especially in adding the latter two herbs.)
Herbs: Siwu Tang (Four Substances Decoction, 4 liang), plus Shudihuang (Radix Rehmanniae Praeparata) and Danggui (Radix Angelicae Sinensis, each 1 liang).
Each dose is 1 liang, decocted in water, and taken orally.
