also: みのわた
san jiao; triple burner; triple heater
A concept in traditional Chinese medicine referring to a functional metabolic system with three parts (upper, middle, lower), not a physical organ. The reading さんしょう is standard; みのわた is rare and archaic.
In Kampo medicine, the san jiao is considered a pathway for qi and fluids.
The classical notation 三の焦 (read みのわた) is rarely used today.
Standard kanji form for the Chinese medicine concept.
Rare variant spelling; reading みのわた is archaic or literary.
From Chinese 三焦 (sānjiāo), literally 'three burners'. The Japanese reading さんしょう is the on'yomi; みのわた is a native Japanese reading of uncertain origin, possibly a calque or old translation.
