Lagundi has become one of the most established and widely used herbal drugs for cough in the country through the various measures taken to promote research and development of traditional medicine. The lagundi-based medication was first licensed by PCHRD to three pharmaceutical companies in 1995 namely, Pascual Laboratories, Inc., Gruppo Medica, Inc. This plant is common and widely distributed in the country. “Lagundi” is a common term for Vitex negundo L., which is traditionally used to treat insect and snake bites, ulcers, rheumatism, sore throat, cough, fever, and clogged sinuses. Lagundi formulation was proven to be effective in preventing the spread of disease-causing microorganisms, reducing fever, decreasing the viscosity of mucus, improving the color of phlegm, alleviating shortness of breath and wheezing, and lessening the frequency of cough. The drug is a product of multiple scientific studies and clinical trials as part of the National Integrated Research Program on Medicinal Plants (NIRPROMP). It is in syrup and tablet forms and is good for both children and adults. The SolutionĪ team of researchers from the University of the Philippines, with support from PCHRD, formulated a lagundi-based drug which can effectively ease the symptoms of respiratory infections specifically cough and asthma. Hence, there is a strong need to validate the efficacy of herbal medications and develop safe and low-cost drugs that are efficient in treating common respiratory infections. kidney disease, hypertension and cancer). The problem, however, is that some traditional medicines, if not ineffective, were found toxic, have side-effects, and may cause more serious complications (e.g. As healthcare remains inaccessible and unaffordable in the Philippines, Filipinos, especially those residing in rural areas, resort to relying on inexpensive alternative sources of treatments such as traditional medicines. Most children acquire multiple respiratory infections during their early years, while asthma remains to be the most common chronic respiratory conditions even for adults. The prevalence of common respiratory infections causes a burden to millions of people worldwide. Dynamic Viscosityĭynamic viscosity determines the shear stress ratio of the fluid to the shear rate.You are here: Lagundi: Anti-cough and anti-asthma medicine | Philippine Council for Health Research and Development Lagundi: Anti-cough and anti-asthma medicine Technology Generator Viscosity has two types that are Dynamic and Kinematic Viscosity. They are synonymous if the fluid density is known. They define the flow of the fluid in various ways, i.e., how they are measured. There are two different viscosity measures used to describe fluids, dynamics and kinematic viscosities. Or it can be measured with household equipment, such as calculating how fast a liquid can travel on a slight incline after a certain period of time. Viscosity can be measured by a viscometer, a piece of equipment that measures the force necessary to move through a liquid. As you'll see in this equation, if the spere's speed is lower, the viscosity would be higher. The SI unit of viscosity is Pascal seconds (Pa s). G is the acceleration because of gravity. ?p is the density between the fluid and sphere tested, Where η (eta) is defined as the viscosity,
