What is medicine
Medicine is a substance or practice used to prevent, treat, or diagnose physical and mental illnesses. In simple words, it helps the body fight germs, manage chronic conditions like diabetes, and relieve pain. Whether as a tablet, liquid, or vaccine, its core purpose is to restore and maintain your health.
What is the definition of medicine?
The World Health Organization (WHO) defines medicine as any substance or product used to modify or explore physiological systems or pathological states for the benefit of the recipient. Academically, medicine (ওষুধ) is the science and practice of establishing a diagnosis, prognosis, treatment, and prevention of disease. It encompasses various health care practices evolved to maintain and restore health by the prevention and treatment of illness. In the Bangladeshi context, this includes allopathic, Unani, and Ayurvedic formulations regulated for safety and efficacy.
History of medicine
The history of medicine is a journey from ancient wisdom to modern molecular science. In our subcontinent, the roots of healing run deep through Ayurveda and Unani (Tibb-e-Unani) traditions. These systems, dating back thousands of years, emphasized a holistic balance between the body and nature, using herbal formulations that are still respected and regulated in Bangladesh today.
As these traditions flourished, the Western world saw the rise of Hippocrates, often called the "Father of Medicine," who shifted the focus from superstition to clinical observation. During the Islamic Golden Age, scholars like Ibn Sina (Avicenna) revolutionized the field. His monumental work, The Canon of Medicine, integrated Greek and Indian knowledge, setting the standard for medical education across the Muslim world and Europe for centuries.
The 19th century marked a turning point with the discovery of germ theory by scientists like Louis Pasteur and Robert Koch. By proving that microscopic organisms cause disease, they paved the way for vaccines, antiseptics, and effective public health measures. This breakthrough transitioned medicine into a rigorous science, leading to the birth of modern pharmacology.
Today, medicine is a high-tech field where we can manufacture complex drugs and map human genetics. In Bangladesh, this evolution is visible in our robust pharmaceutical sector, where companies produce life-saving generic medicines under the strict oversight of the Directorate General of Drug Administration (DGDA).
Traditional Medicine in Bangladesh
In Bangladesh, healthcare is a rich blend of modern science and deep-rooted heritage. Traditional medicine, primarily comprising Unani (Tibb-e-Unani) and Ayurvedic practices, remains a vital part of the cultural and medical landscape. These systems utilize natural herbs and minerals to promote holistic healing and are often the first point of care for many in both rural and urban areas.
Importantly, these are not unregulated practices; the Directorate General of Drug Administration (DGDA) strictly oversees the manufacturing and sale of traditional medicines to ensure they meet safety and quality standards. This formal regulation integrates our ancient wisdom into the national healthcare system, making traditional medicine a respected and safe complement to modern allopathic treatment.
What are the main types of medicine?
Medicine is classified into several categories based on how they are obtained and their specific functions in healthcare. In Bangladesh, these types are common across community clinics, pharmacies, and hospitals:
-
Prescription Medicine: These are potent medications that require a registered doctor’s signature to purchase, such as antibiotics for typhoid or respiratory infections.
-
Over-the-Counter (OTC): These medicines can be bought directly without a prescription for minor ailments, such as paracetamol or saline.
-
Herbal and Traditional: This includes natural formulations from Unani and Ayurvedic traditions, which are regulated by the DGDA to ensure they are safe for use alongside modern treatments.
-
Vaccines: These are specialized medicines used to train the immune system to prevent diseases like Polio, Dengue, or COVID-19 before they occur.
What are the purposes of medicine?
Medicine serves three primary roles in maintaining and improving our health:
-
To Treat Disease: Medicines are used to cure or manage illnesses by killing germs, replacing missing substances in the body, or reducing symptoms. For example, antibiotics are used to treat infections like typhoid or pneumonia.
-
To Prevent Illness: Certain medicines, such as vaccines, are administered to healthy individuals to stop a disease before it starts. In Bangladesh, vaccines are crucial for preventing conditions like Polio or Hepatitis B.
-
To Diagnose Conditions: Some substances are used as medical tools to help doctors identify what is wrong inside the body. This includes dyes used during X-rays or specialized liquids used in laboratory tests.

How is medicine different from a drug?
While the words "medicine" and "drug" are often used interchangeably in daily conversation, there is a subtle but important distinction in a healthcare context. In Bangladesh, the term "drug" can sometimes carry a negative social association with narcotics (মাদকদ্রব্য), but scientifically, it has a broader meaning.
-
A Drug: This is any chemical substance that, when consumed, changes the way the body or mind functions.
-
A Medicine: This is a drug that is specifically used for a therapeutic purpose—meaning it is designed to prevent, alleviate, or cure a health condition.
Essentially, all medicines are drugs, but not all drugs are medicines. For a drug to be considered a medicine, it must be safe, effective, and used to help or heal the recipient.
Who regulates medicine in Bangladesh?
In Bangladesh, the safety, quality, and efficacy of all pharmaceutical products are overseen by the Directorate General of Drug Administration (DGDA). As the central regulatory authority under the Ministry of Health and Family Welfare, the DGDA monitors everything from the import of raw materials to the manufacturing and marketing of finished drugs. This strict regulation is vital because it ensures that the medicine you buy at a local pharmacy is genuine, properly dosed, and free from harmful contaminants. By maintaining the Essential Drugs List and supervising local giants like Square and Beximco, the DGDA builds trust in our national healthcare system, ensuring that every tablet or syrup meets international safety standards.
Conclusion
Medicine is far more than a simple remedy; it is a vital science dedicated to preventing, diagnosing, and treating illness to improve our quality of life. From ancient traditions and scholars like Ibn Sina to today’s DGDA-regulated pharmaceutical industry in Bangladesh, its goal remains constant to restore and maintain health. Understanding these principles empowers you to make better healthcare decisions, using medicine as an essential bridge between illness and recovery.
