Fusion—sequential use—Scenario 2: In fusion—sequential use, the biomedical system complements the local medical system, expanding therapeutic options. Complementarity unfolds sequentially over time, observed in the evolution of treatment strategies. In the first scenario without hybridization, the local system treats vomiting with medicinal plants, while the biomedical system uses medications. The second scenario, involving hybridization, illustrates sequential use, where the initial treatment (Time 1) is with one system, and if there is no improvement, it transitions to the other (Time 2)
