Rainforest Tree Extract Targets Covid-19 on Multiple Fronts

Researchers studying Copaifera lucens from Brazil’s Mata Atlântica found galloylquinic acids in its leaves that exhibit a multitarget attack on covid-19 by binding the spike protein’s receptor-binding domain and inhibiting the virus’s papain-like protease and RNA polymerase, suggesting a multi‑target approach that could slow future variants and even affect HIV-1, though in‑vivo and clinical trials are still needed.
