☯ TCM Properties
Tonifies the Middle and Augments Qi; Strengthens the Spleen and Harmonizes the Middle; Eliminates Irritability and Relieves Thirst; Stops Dysentery; Generates Fluids; Protects the Stomach
Traditional Chinese Uses
Jing Mi (polished white rice, japonica rice) is a neutral, sweet grain-food used as a tonic in Chinese medicine. It supplements the middle burner, strengthens the Spleen and Stomach, generates Body Fluids to relieve thirst, and stops mild forms of diarrhea from Spleen deficiency. As the most staple of all foods in Chinese culture, its medicinal role reflects the TCM principle that food is medicine — providing nourishment and Spleen support through everyday dietary use. It also appears as a culinary medium in many herbal porridge recipes.

Botanical Description
Oryza sativa, Asian rice or Jing Mi, is an annual cereal grass in the Poaceae family, domesticated in the Yangtze River basin and now the staple grain for over half the world's population. Cultivated plants grow 60-180 cm tall with hollow jointed culms, linear flat leaves with prominent ligules, and terminal panicles 20-40 cm long bearing spikelets that each produce a single grain. The caryopsis (hulled and polished as white rice, or partially polished as brown rice) is the medicinal and culinary product. Jing Mi specifically refers to non-glutinous polished rice. Cultivation requires flooded paddies or wet upland fields.
Active Constituents
Starch (amylose and amylopectin)
Carbohydrate (polysaccharide)Concentration: ≈ 75–80% of polished grain by dry weight
The dominant component of polished non-glutinous rice; a readily digestible energy source that provides the sweet, harmonising, spleen-strengthening quality central to Jing Mi's role of tonifying the middle and augmenting qi.
Rice protein (oryzenin / glutelin)
ProteinConcentration: ≈ 6–8% of the grain
The major storage protein of rice endosperm; a hypoallergenic protein contributing to the nourishing, restorative value of rice congee used to protect the stomach and generate fluids.
B-group vitamins (thiamine, niacin, riboflavin)
Water-soluble vitaminsConcentration: Modest in polished grain (concentrated in bran, reduced by milling)
Coenzymes for carbohydrate energy metabolism; present in reduced amounts in polished rice compared with brown rice, contributing to its supportive, tonifying nature.
γ-Oryzanol
Ferulic-acid esters of triterpene alcohols/sterolsConcentration: Low in polished grain (mainly in bran, largely removed by milling)
A characteristic rice antioxidant complex with lipid-lowering and antioxidant activity; largely removed during polishing, so present only in trace amounts in Jing Mi but notable in the bran fraction.
Dietary fibre and resistant starch
Carbohydrate (non-digestible)Concentration: Low in polished rice; increased when cooked and cooled
Supports gut function and moderates glucose release; contributes to the gentle, harmonising effect on the digestive tract attributed to rice.
Minerals (magnesium, phosphorus, potassium)
MicronutrientsConcentration: Modest amounts
Essential minerals supporting energy metabolism and fluid balance, complementing rice's traditional actions of relieving thirst and generating fluids.

Preparation Methods
Medicinal congee (Zhou / rice gruel)
Parts: Polished non-glutinous rice grain
Rice is simmered slowly with ample water into a thin gruel; taken warm to tonify the middle, strengthen the spleen, harmonise the stomach, generate fluids and relieve thirst. Often the base for medicinal congees combined with other tonic herbs.
Decoction adjunct in classical formulas
Parts: Polished rice grain
Added to decoctions such as Bai Hu Tang (White Tiger Decoction), where non-glutinous rice protects the stomach and moderates the cold, draining action of gypsum and anemarrhena while generating fluids.
