Chinese sweet leaf is a Rubus plant, a relative of raspberry, whose leaves are brewed into a naturally sweet tea and contain plant compounds called polyphenols. People mostly look at it for allergy symptoms, but the evidence is very limited: one placebo-controlled trial of 89 people with dust mite allergy found no clear difference in symptoms or nasal congestion. It was a single small study, so it is too early to say more.
