Women who experience difficult and scanty menstruation, abdominal distension, edema of the feet, and infertility are often thought to suffer from heat in the Small Intestine. However, it is actually due to the failure of Qi transformation in the Bladder (Bladder). The Bladder is originally located close to the Chongmai and Renmai vessels (uterus/womb). When the Bladder is diseased, the uterus is also affected. Water-dampness qi naturally flows into the Bladder, but the Bladder cannot transform it on its own; it requires the connection of Kidney Qi to transform water and discharge Yin Qi. If the Bladder lacks the connection of Kidney Qi, its Qi transformation will not function, and water-dampness qi will inevitably seep into the uterus, creating a vast expanse of water. How can such a watery field generate life? The treatment method must strengthen Kidney Qi to separate and eliminate dampness in the uterus, and benefit Kidney Fire to facilitate the transformation of water in the Bladder. By strengthening the Root of Pre-Heaven (Kidney), the Qi transformation of the Bladder is restored, dampness in the uterus is eliminated, and the vast watery field is transformed into a ladder for rain and dew. When water metabolism is normal, the Bladder is unobstructed; when Kidney Fire is vigorous, the uterus is warm. How could sowing seeds fail to sprout and grow?

Prescribe Huashui Zhongzi Decoction (Water-Transforming Seed-Nourishing Decoction).
Morinda officinalis Radix (Bajitian) (30g, soaked in salt water)
Atractylodis Macrocephalae Rhizoma (Baizhu) (30g, stir-fried with soil)
Poria (Fuling) (15g)
Ginseng Radix et Rhizoma (Renshen) (9g)
Cuscutae Semen (Tusizi) (15g, stir-fried with wine)
Euryale Semen (Qianshi) (15g, stir-fried)
Plantaginis Semen (Cheqianzi) (6g, stir-fried with wine)
Cinnamomi Cortex (Rougui) (3g, remove coarse bark and grind)

Decoct in water and take orally. After two doses, the Qi transformation of the Bladder is restored; after four doses, the symptom of difficult menstruation is eliminated. After another ten doses, the forms of false distension and foot edema disappear. Continue taking for sixty doses, and Kidney Qi will become very vigorous, the uterus will be warm, making conception and childbirth easy. This formula benefits the water of the Bladder entirely by supplementing the Qi in the Kidney; it warms the Qi of the uterus entirely by strengthening the Fire in the Kidney. As for herbs that tonify the Kidney, most are moistening substances; would they not exacerbate dampness by adding wetness? However, the herbs in this formula are ingenious in tonifying Kidney Fire rather than Kidney Water. It is especially ingenious that it tonifies Fire without the risk of being drying and harsh, and promotes urination without being violently purgative. Thus, the Qi transformation of the Bladder is normal, the uterus is not damp, and growth and nourishment are endless.

Marginal Note: Difficult urination, abdominal distension, and foot edema are very common symptoms. Not only do they prevent conception, but they also temporarily add miscellaneous diseases. If untreated for a long time, they may even develop into incurable consumptive diseases (Lao Zhai). This formula tonifies Water without aiding dampness, and tonifies Fire to return it to its source. Its efficacy is excellent, and no single herb should be added or subtracted. If good Cinnamon Bark (Rougui) is unavailable, substitute with one qian (3g) of Psoraleae Fructus (Pogu Zhi/Buguzhi) stir-fried, using two Walnuts (Hetaoren) with skin burnt black, peeled, and the kernel used as a guide drug. If good Cinnamon Bark is used, Walnut guide drug is unnecessary.

Song Verse:
Difficult urination, abdominal distension, and foot edema,
Are solely due to dampness filling the uterus.
Benefiting Bladder water and strengthening Kidney Fire,
Turns vast watery fields into fertile land.
Huashui Zhongzi uses Morinda, Atractylodes, and Poria together with Plantago seed.
Ginseng, Euryale, and Dodder seed,
Plus Cinnamon Bark to return Fire to its source.
