Lagundi (scientific name: Vitex negundo; English name: five-leaved chaste tree) is a shrub that grows in tropical and subtropical places like the Philippines. It is one of the 10 herbal medicines endorsed by the Department of Health as effective treatments with proven therapeutic value.
Lagundi is said to be an effective treatment for flu, colds, chronic bronchitis, bronchial asthma, and pharyngitis. It can prevent the body from producing asthma-inducing substances known as leukotrienes. Lagundi contains a substance called chrysoplenol D, which regulates allergic reactions and relaxes the muscles.
Apart from problems in the respiratory system, lagundi’s root has also been reported to offer relief for boils, dyspepsia, rheumatism, and leprosy. Its flowers can strengthen the heart as well as cure liver diseases, intestinal worms, diarrhea, and even cholera.
You can either buy lagundi in capsule or syrup form in drug stores or brew fresh or dried lagundi leaves at home.
To make your own lagundi tea, simply boil about ½ cup chopped lagundi leaves in 2 cups of water for 10 to 15 minutes. Drink ½ cup of the produced tea thrice daily until symptoms dissipate.
For skin diseases, wounds, and boils apply decoction directly onto the skin.
