History
Chenopodium formosanum was a key component of the diets of Formosan indigenous peoples, but  it had largely disappeared from cultivation by the 2000s. Renewed interest in traditional foodstuffs has led to a revival of production with cultivation in Taitung County expanding from 40 hectares in 2015 to 200 hectares in 2018. This rapid expansion quickly glutted the market and surplus produce had to be stored.

Chenopodium formosanum is part of the Slow Food Foundation for Biodiversity's Ark of Taste.
