This is the recipe for home-made ORS.
The ORS recipe recommended by WHO and UNICEF (also known as reduced-osmolarity ORS) is:
bb("Compound"color(white)(mmml)"g/L"color(white)(m)"mmol/L"color(white)(m)"mOsmol/L")
"NaCl"color(white)(mmmmmmmll)2.6color(white)(mmll)44.5color(white)(mmmmm)89

"Na"_3"C"_6"H"_5"O"_7·2"H"_2"O" is sodium citrate dihydrate.
The normal osmolarity of blood is about 300 mOsmol/L.
