In the '90s, Dr. Neila Cortes-Maramba of UP Manila led a team of scientists investigating ten medicinal plants in the Philippines. Two of these plants exhibited promising results—one for cough and the other for urinary tract infections. The team patented Vitex negundo (Lagundi) and Blumea balsamifera (Sambong) in syrup and tablet forms, granting them exclusive rights to these medicines.
