Lagundi is a common medicine shrub in the Philippines, and grows wild in many places like Mt. Banahaw. The use of Lagundi for medicinal purposes has a long history in the Philippines. The Philippine Department of Health has certified Lagundi as a medicinal plant for treatment in cases of colds, flu, pharyngitis, and asthma. Today, pharmaceutical companies sell it in tablet form at drug stores. A new cough syrup for children made from Lagundi is also on the market now. These products are approved by the Bureau of Food and Drugs.
