Why people make this drink
When the weather turns warm and humid, some children (and adults) become noticeably irritable, lose their appetite, or feel generally flat and unwell — without having any specific illness. In traditional Chinese food therapy, this pattern is often associated with internal dampness and heat building up in the body. This mild, pleasantly sweet drink has long been used as a household remedy to help clear that lingering heat and restore a sense of calm and vitality. It is also traditionally given to infants before and after routine vaccinations to help support comfort during that period.

Vascular endothelial function improved in the adlay group, especially in those over 40.Limitation: Participants were healthy adults and the outcomes were surrogate markers, so the results say little about clinical disease outcomes. Tea is a polyphenol-rich extract, not whole grain.PubMed 38945894 · 2 more job's tears (coix) studies
