Traditional medicines come from plants and are not chemically processed, but they can still be toxic to the liver or interact with other medicines. Modern medicines are made by scientists in laboratories based on natural substances. They include analgesics for pain relief, antibiotics for bacterial infections, and psychotherapeutic medicines for mental illnesses. Both traditional and modern medicines can have side effects, with modern medicines more likely to cause issues like bleeding, allergies, addiction, or changes in behavior or emotions depending on the type of drug. Correct usage of medicines is important.
