The cloudy, starchy water left from cooking or soaking rice, given warm and lightly salted to a person — especially a child — with diarrhea, to replace fluid and ease the gut. One of the most life-saving simple remedies humans ever found.
In the rice-growing Lowcountry — the heart of Gullah-Geechee country, built on the rice knowledge of enslaved West Africans — rice water for a sick baby was common knowledge. The same people whose stolen rice expertise built Carolina fortunes kept their own children alive with the water from the pot.
Rice water is ancestral oral rehydration, and the science behind it is profound: the glucose and starch released from rice activate the gut's sodium-glucose cotransport, which pulls salt and water across the intestinal wall and back into the body even while diarrhea is flushing it out. This is the exact principle behind modern Oral Rehydration Solution (ORS), credited with saving tens of millions of children's lives worldwide — and rice-based ORS has been shown to reduce stool output and shorten illness compared to plain sugar-salt solutions. Given warm and lightly salted to a child with diarrhea, rice water replaces fluid and electrolytes, settles and gently feeds the irritated gut, and buys time for recovery. In the era before clinics, this cloudy water was the difference between a child living and dying of dehydration, and that knowledge ran through Gullah and West African kitchens.
Either reserve the cloudy water poured off cooked rice, or boil a tablespoon of rice in two cups of water and strain off the liquid, or soak clean rice and use the soaking water cooked briefly. Cool to warm, add a small pinch of salt (and, for older children and adults, a little sugar or a mashed banana for potassium). Give in small, frequent sips to a child with diarrhea.
