In this interdisciplinary project, students become herbal scientists and agricultural engineers by developing a natural cough medicine, starting from seed to solution. Their first task is to research and select a plant with proven cough-relieving properties, such as thyme, basil, or licorice. Then, students design and build a custom hydroponic system optimized for the plant’s growth, carefully selecting parameters like water flow, pH levels, and nutrient balance. Once the plant is thriving, they harvest it and follow a documented process to extract the active compounds and formulate the cough remedy. Throughout the project, students learn key concepts in biology, chemistry, health science, and sustainable food-tech. The experience connects the dots between agriculture, pharmacology, and green innovation, empowering students to see how nature and science can work hand-in-hand to create real-world health solutions. The final outcome? A student-grown, student-made herbal medicine from a fully sustainable, soil-free system.
