NCT ID NCT06472791
First seen Jul 01, 2026 · Last updated Jul 01, 2026
Summary
This study investigates whether a dietary supplement made from centella asiatica, also known as gotu kola, can improve the function of blood vessels in adults aged 50 to 85. Participants take either the herb or a placebo for four weeks, and researchers measure changes in blood vessel flexibility using a non-invasive finger device. The goal is to see if this traditional herb can help maintain vascular health as people age.
