First seen Jan 26, 2026 · Last updated May 15, 2026 · Updated 13 times
Summary
This study tested the safety of a purified green tea extract called EGCG in 50 people with idiopathic pulmonary fibrosis (IPF), a lung scarring disease. Participants took EGCG or a placebo daily for 12 weeks. The main goal was to see if EGCG is safe and how it interacts with standard IPF medications. This early-phase trial focused on safety, not on curing the disease.
