☯ TCM Properties
Tonifies Qi and tonifies the Spleen and Stomach; Relieve restlessness, removes toxicity and relieves thirst
Traditional Chinese Uses
Shu Mi is the grain of broomcorn (proso) millet, Panicum miliaceum, a food-grade substance used as a gentle Qi-tonifying and digestive remedy. Sweet with a warm (some sources slightly cool for the glutinous form) nature, it enters the Spleen, Stomach, and Lung channels. It tonifies the Qi and harmonizes and strengthens the Spleen and Stomach, making it suitable for fatigue, digestive weakness, and diarrhea from Spleen deficiency. It also relieves restlessness (irritability), resolves toxicity, and relieves thirst, and is used for nausea and vomiting.
As a mild, nourishing grain it is most often prepared as a decoction or cooked into a warm porridge (congee) for convalescence and to ease excessive thirst; externally the cooked grain has been applied to scalds and mouth sores.

Botanical Description
Shu Mi is the grain of Panicum miliaceum (Poaceae), broomcorn or proso millet, an erect annual grass 40 to 120 centimetres tall with cylindrical, often hairy culms and swollen nodes. The linear-lanceolate leaf blades are rough and softly hairy, with hairy sheaths. Unlike the dense bristly spike of foxtail millet, the inflorescence is a loose, open, often nodding panicle 10 to 30 centimetres long, its slender drooping branches bearing bristleless, ovoid spikelets each with a single fertile floret. The rounded grain, about 3 millimetres across, may be white, cream, yellow, red or brown when hulled. A drought-hardy short-season cereal, its dried seed is used as food and medicine.
A cultivated dry-farming cereal of warm-temperate croplands, tolerant of drought and poor soils; grown across northern China and Eurasia, occasionally persisting as a weed of fields.
Active Constituents
Starch (amylose/amylopectin)
PolysaccharideConcentration: the dominant fraction of the dehulled grain; amylose content and starch granule size vary widely between accessions, including waxy (near-zero amylose) landraces
Determines the grain's digestibility and glycaemic behaviour. Accession screening of twenty-five worldwide Panicum miliaceum lines found large genotype-driven differences in starch characteristics, so glycaemic claims made for one cultivar do not transfer to another.
Prolamin (panicin) storage protein
Alcohol-soluble cereal storage protein (prolamin)Concentration: the major protein class of the endosperm
Proso millet protein is unusually rich in branched-chain amino acids and leucine and poor in lysine. Concentrated proso millet protein fed to rodents raised plasma HDL cholesterol and adiponectin and lowered glucose and insulin, effects attributed largely to this prolamin-rich fraction rather than to the starch.
Ferulic acid
Hydroxycinnamic acid (phenolic acid)Concentration: present mostly in insoluble bound form, esterified to arabinoxylan in the bran/cell wall rather than free in the endosperm
The principal phenolic acid of the grain and the main contributor to its antioxidant capacity. Because it is largely wall-bound, it is released only on milling, fermentation, germination or colonic microbial hydrolysis, so whole-grain preparations and decoctions of husked grain differ substantially in free phenolic content.
p-Coumaric acid
Hydroxycinnamic acid (phenolic acid)A secondary bound phenolic acid of the pericarp, co-occurring with ferulic acid and contributing to the radical-scavenging activity measured in whole-grain extracts.
⚠ Drug Interactions
Insulin and oral hypoglycaemic agents (e.g. metformin, sulfonylureas)
Whole-grain proso millet lowered fasting glucose and improved glucose handling in type 2 diabetic mice, and proso millet protein concentrate raised adiponectin and lowered insulin in obese diabetic mice. There is no human pharmacokinetic or pharmacodynamic interaction study with any antidiabetic drug, so this rests on rodent data and on the general dietary effect of substituting a lower-glycaemic grain.
Clinical note: No dose change is required for medicinal amounts. If a patient is asked to make proso millet a dietary staple while taking insulin or a sulfonylurea, ask them to monitor capillary glucose for the first one to two weeks.
Millet (Panicum miliaceum) allergy - relevant to any millet-containing preparation, including birdseed exposure
Immediate-type sensitisation to Panicum miliaceum is documented in atopic bird keepers exposed to millet-containing seed mixtures, with specific IgE demonstrated on immunoblot against a 60 kDa protein in birdseed millet and against 60 kDa and 36 kDa proteins in common millet. Sensitisation acquired by inhalation can then be expressed as food allergy on ingestion.
Clinical note: Rare, but ask about bird keeping before prescribing millet-based congee or Shu Mi preparations to an atopic patient, and stop it if oral itch, wheeze or urticaria follow a dose.
Dui Yao — Herb Pairs
The classical two-herb combinations this herb appears in, each with an action neither herb has alone.
Transforms phlegm and harmonizes the stomach while nourishing the stomach, so that yang can enter yin and sleep returns.
Insomnia from stomach disharmony ('when the stomach is not harmonious, sleep is not peaceful').
Core pair of a classical formula — Ban Xia Shu Mi Tang, Ling Shu (Huang Di Nei Jing)

Clinical Studies
Whole Grain Proso Millet (Panicum miliaceum L.) Attenuates Hyperglycemia in Type 2 Diabetic Mice: Involvement of miRNA Profile
Whole-grain proso millet fed to type 2 diabetic mice reduced hyperglycaemia and altered hepatic microRNA expression associated with glucose and lipid handling. An animal study of the whole grain as a food, not of a medicinal extract or a defined dose in humans.
Effects of Dietary Korean Proso-Millet Protein on Plasma Adiponectin, HDL Cholesterol, Insulin Levels, and Gene Expression in Obese Type 2 Diabetic Mice
Proso millet protein concentrate fed to obese type 2 diabetic mice on a high-fat diet raised plasma HDL cholesterol and adiponectin and lowered glucose and insulin relative to casein. The effect tracked the protein fraction rather than the whole grain.
Immediate-Type Respiratory Allergy to Millet-Containing Seed Mixture of Bird Food
Case documentation of immediate-type respiratory allergy to millet in bird keepers, with specific IgE against millet proteins demonstrated by immunoblot. Establishes Panicum miliaceum as a genuine, if uncommon, inhalant and food allergen.
