Jiaogulanin käytössä havaitut terveysvaikutukset ovat herättäneet mielenkiinnon yrttiä kohtaan. Jiaogulanista onkin tehty tieteellisiä tutkimuksia, joissa sen terveyttä edistävät vaikutukset on todettu. Amerikkalainen tietopalveluyritys Wolters Kluwer on koonnut yhteen Jiaogulania (Gynostemma pentaphyllum) koskevia tutkimuksia:
