Millet, Black Glutinous Rice and Coix Seed Porridge (San Mi Zhou)

Why people make this porridge

In traditional Chinese medicine, the spleen and stomach are considered the root of all qi and blood — when they function poorly, phlegm and dampness accumulate, circulation slows, and the risk of health problems including cardiovascular issues rises. This simple three-grain porridge is Bro Niu’s go-to preventive kitchen remedy: millet for the spleen, black glutinous rice for the kidneys and brain, and toasted coix seed to help the body manage moisture and reduce dampness.

Millet has been eaten in China for thousands of years. Its warm golden colour signals a concentration of carotenoids and B vitamins. It contains tryptophan, which the body uses to produce serotonin — relevant to both sleep and mood. Black glutinous rice, sometimes called “medicine rice” or “black pearl” in historical texts, is traditionally valued for its warm, nourishing quality and its ability to tonify the kidneys and support brain function. Toasting the coix seed before use is a small but important step — it transforms the grain from cooling to more spleen-friendly, making the porridge easier to digest.

Who it suits / who should be cautious

• Suitable for all ages including children and the elderly
• Especially helpful for older adults with fatigue, poor circulation, or those who want a simple cardiovascular wellness habit
• Diabetic individuals may eat this — in moderation, 3 times per week — but should monitor blood sugar
• Pregnant women should omit the coix seed; substitute with white rice or more millet instead
• Neutral in thermal nature — neither too warming nor too cooling

Why these ingredients (the food-therapy logic)

• Millet (xiao mi): Rich in carotenoids, B vitamins, iron, and tryptophan. Traditionally considered the most spleen-tonifying grain. Particularly helpful for elderly people with qi and blood deficiency — regular consumption is associated with nourishment, anti-aging support, and improved sleep quality.
• Black glutinous rice (hei nuo mi): Historically called “medicine rice” and “black pearl.” Warm and tonifying in nature, traditionally valued for supplementing middle qi, nourishing the brain and kidneys, warming the spleen and stomach, and providing high calcium for bone and dental health. Also associated with supporting liver-kidney deficiency patterns with dizziness, ringing ears, and weak knees.
• Coix seed / Job’s tears (yi mi): When used raw, coix seed is cool and strongly dampness-resolving. Dry-toasting it in a dry wok until fragrant shifts its nature to be more spleen-harmonising and warming — always toast first for this porridge. Helps with smooth bowel function and fluid metabolism.

Ingredients (3–4 bowls)

Ingredient	Amount	Notes
Millet (xiao mi)	2 liang (~75 g)	Rinse and soak briefly
Black glutinous rice (hei nuo mi)	1 liang (~37 g)	Rinse and soak briefly
Coix seed / Job’s tears (yi mi)	3 liang (~112 g)	Dry-toast in a wok without oil until fragrant before use — this is key to the health benefit
Water	8 rice bowls (approx. 1.6 litres)

Method

1. Dry-toast the coix seed in a clean wok over medium-low heat, stirring frequently, until fragrant and lightly golden. Set aside.
2. Rinse the millet and black glutinous rice. Soak for 15 to 20 minutes.
3. Combine all three grains with 8 bowls of water in a pot.
4. Bring to a boil, then reduce heat and simmer for 1 to 1.5 hours, stirring occasionally, until thick and creamy.
5. Serve plain, or with a small amount of red sugar, rock sugar, or as a savoury base with minced meat.

Bro Niu’s tips

• Toasting the coix seed before cooking is not optional if spleen support is the goal — the process converts its cold, damp-draining nature into something more harmonious and easier on digestion.
• This porridge works both sweet and savoury — add rock sugar or red sugar for a sweet version; stir in minced meat or a few red dates for a savoury meal.
• Suitable even during a mild cold — just hold back on sugar to avoid generating more phlegm.
• For those with high uric acid, add 1 liang of red adzuki beans (chi xiao dou) — they help the body process uric acid without the high-purine concerns of most beans.
• If cooking in a rice cooker with millet, be aware that the small grains may overflow through the steam vent — keep an eye on it.

Community questions answered (selected)

• Q (Emily): My mother had a stroke two days ago. The hospital allows me to bring thick porridge. What should I cook for her? Bro Niu: Fresh burdock root (xian niu bang) is particularly beneficial after a stroke. Slice it thinly and cook it with lean pork or dried scallops to make a congee. Try 3 to 4 consecutive days.

• Q (Bobo): My child finds this porridge tasteless and does not want to eat it. Can we add a little red sugar or rock sugar? Can we have it during a cold? Bro Niu: Yes, it works well both sweet and savoury — red dates, rock sugar, red sugar, or minced meat all work. During a cold it is fine, but use less sugar to avoid aggravating phlegm.

• Q (琪琪): Can people with diabetes eat this porridge? Bro Niu: Yes, diabetic individuals may have this porridge — about 3 times per week is appropriate.
