What is Jing Mi? Are Nuo Mi, Xian Mi and Yi Yi Ren the same?
Jing Mi (粳米) is the kernel of japonica rice, Oryza sativa subsp. japonica, used as both food and medicine. Nuo Mi is the glutinous variety: sweet-warm, supplements the center, boosts qi, fortifies the Spleen and stops diarrhea, but is sticky and hard to digest. Xian Mi is indica rice: sweet-warm, warms the center and boosts qi, and is drier. Yi Yi Ren is sweet-bland and cool: promotes urination, percolates damp, fortifies the Spleen, eliminates impediment and clears heat to expel pus. The pharmacopoeial name is Coicis Semen. Write Jing Mi. Use caution in damp fullness.
What are the TCM properties and traditional uses of Jing Mi?
Zhonghua Bencao records Jing Mi as sweet and neutral, entering the Spleen, Stomach and Lung channels, and acting to supplement qi, fortify the Spleen, eliminate vexing thirst and stop diarrhea and dysentery. It is used for Spleen-Stomach qi vacuity, poor appetite, fatigue, vexation with thirst, and diarrhea or dysentery. Sweet-neutral and Stomach-protecting, it suits Spleen vacuity with vexing thirst—not damp fullness of the center, or newly harvested rice that stirs qi.
Does Jing Mi need special processing? Can glutinous rice replace it?
Use it raw in porridge or decoct it with the formula; dry-frying until scorched can fortify the Spleen and stop diarrhea. In Bai Hu Tang and Zhu Ye Shi Gao Tang it is decocted with gypsum until the rice is cooked, to protect Stomach qi. Glutinous rice is warm and sticky; it cannot replace eliminating vexation and stopping thirst by equal weight. Instant porridge is not the rice of the formula.
What is the usual dosage? Can it be eaten daily as a qi-supplement porridge?
In decoction the usual amount is 9–30 g, or it is cooked as porridge. In Bai Hu Tang-type formulas, stop when the rice is cooked and the decoction is formed. As a staple it may be eaten daily, but scorched rice is drying; except for center-cold diarrhea, long use may assist fire. Vexing thirst and diarrhea need a practitioner to name a short pairing; it does not replace dehydration assessment.
What are the contraindications? Can it be used in pregnancy?
Use caution in damp fullness of the center and with newly harvested rice that stirs qi. Scorched rice assists fire; use caution in yin-vacuity fire. In pregnancy it is generally edible as a Stomach-nourishing food; formula pairing needs a practitioner’s assessment. Reduce the amount if abdominal distention and sour belching appear. Cholera with vomiting and diarrhea approaching collapse, when even rice water cannot be taken, is an emergency.
Can Jing Mi supplement qi, fortify the Spleen, eliminate vexing thirst and stop diarrhea?
It can help Spleen-Stomach qi vacuity and protect the Stomach in febrile disease. Vigorous heat with vexing thirst joins gypsum, Anemarrhena and Licorice in Bai Hu Tang. Residual heat with counterflow appears in Zhu Ye Shi Gao Tang. Lung-Stomach fluid damage appears in Mai Men Dong Tang. It supplements qi, fortifies the Spleen, eliminates vexing thirst and stops diarrhea and dysentery—not a specific for every diabetic thirst or every diarrhea.
Can Jing Mi be eaten daily as a Stomach, antidiarrheal or fire-reducing porridge?
Spleen vacuity with poor appetite may be nourished with porridge; damp fullness only distends further as it supplements. “Rice must lower glucose and stop diarrhea” does not replace glucose and bowel assessment. Supplementing qi, fortifying the Spleen and eliminating vexing thirst should name 9–30 g inside a Bai Hu Tang-type formula.
How do you choose among Jing Mi, Nuo Mi, Shan Yao, Yi Yi Ren and Gan Cao?
Non-glutinous rice is sweet-neutral: supplements qi, fortifies the Spleen, eliminates vexing thirst and stops diarrhea—protects the Stomach without stickiness. Glutinous rice is sweet-warm: supplements the center and boosts qi, sticky; a small amount may suit vacuity-cold diarrhea. Chinese yam is sweet-neutral: supplements the Spleen, nourishes the Stomach, generates fluids, boosts the Lung, supplements the Kidney and secures essence. Coix is sweet-bland and cool: promotes urination, percolates damp, fortifies the Spleen and eliminates impediment. Licorice is sweet-neutral: supplements the Spleen, boosts qi, clears heat, resolves toxin and harmonizes the formula. Febrile Stomach protection favors Jing Mi (Bai Hu Tang); a little Nuo Mi may suit vacuity-cold diarrhea; chronic Spleen-vacuity diarrhea favors Shan Yao; heavy damp favors Yi Yi Ren; harmonizing favors Gan Cao. They may be paired; damp fullness forbids large Nuo Mi, and yin vacuity forbids scorched rice.
Which herbs is Jing Mi combined with? What are the representative formulas?

Lung-Stomach fluid damage appears in Mai Men Dong Tang. Write Jing Mi 9–30 g, cooked until the rice is done; do not replace it with glutinous rice by equal weight.
How do you choose and store Jing Mi?

Buy japonica rice kernel; do not replace supplementing qi, fortifying the Spleen, eliminating vexing thirst and stopping diarrhea with glutinous rice or coix by equal weight.
