There are many types of medicinal plants or herbs. Medicinal plants and herbs promote health with their roots, leaves and flowers. They reduce symptoms of disease or aid in recovery. Since the beginning of human history, people have used plants and herbs to heal wounds or treat all kinds of ailments. Modern medicine and drugs replaced the original, unprocessed use of plants. Some of these plants are the basis of medicines, while others are considered only a home remedy.
What are medicinal plants and herbs?
History
The use of plants to treat wounds, pain or disease was initially based on people's own experience. Throughout history, herbal medicine developed into a separate branch of knowledge. Literary sources on plants as remedies date back to the Sumerians, inhabitants of Sumer, a land region and civilization localized in the southern part of Mesopotamia. Healing using plants extends throughout the populated world.
Old traditions
History shows that medicinal plants were known to Native Americans, to the cultures of Central and South America, and to the peoples of Africa and Asia. Also, the ancient Egyptians and Greeks practiced herbal medicine, whose written sources influenced traditional healers into the Middle Ages and modern times. Monks and monasteries resorted to these sources and supplemented ancient knowledge with new insights.
Plant Medicine
A medicinal plant has the advantage of being available to everyone. It can be sought and picked in the wild. Medicinal plants whose constituents or active substances serve as the basis or ingredient of medicines are considered medicinal plants. A distinction can be made between plants, whose healing effects have been scientifically researched and proven, and those plants that are only traditionally used as remedies.
Plant or Herb?
Whether something is a plant or an herb depends on the purpose for which it is used. Any plant that has useful uses is an herb in the broadest sense. Chamomile tea is considered an herbal tea, but chamomile that you grow in your garden is just considered a plant.
Plants with healing properties
The use of medicinal plants is also known as phytotherapy (“treatment with plants”). For milder diseases or conditions, medicinal plants are often a good alternative to drugs. The healing properties are in the essential oils in the plant and the tannins (chemical compounds), but also in the various excipients that together produce a combined effect that is stronger than their individual activity.
In 2022, there is plenty of scientific research taking place into (the effects of) medicinal plants and the potential for new areas of application is great.
The areas where the active ingredients of plants have a beneficial effect include colds, respiratory diseases or dyspepsia. However, plant substances can also be used in the area of skin disorders and rashes. In addition, medicinal plants are used for fatigue, nervousness, anxiety, restlessness or mild depression.
People who resort to herbal remedies, for example for depression or sleep disorders, are best advised to consult their doctor in advance, as the active ingredients in the plants sometimes cause side effects, interact with medications or are restricted.

Limitations of plant medicine
The limits of plant medicine are in the treatment of serious injuries, conditions or diseases. Serious diseases such as cancer or HIV/AIDS cannot be treated or cured with a single plant. A second limit is improper dosage or application.
You can even overdose on a plant's natural active and medicinal ingredients if you use them in the wrong way. Then they turn out to be toxic and harmful. A medicinal plant contains active ingredients that affect the body in one way or another, but in the wrong amount or when used in the wrong way, symptoms can arise.
Application and dosage
For the application of medicinal plants, there are several methods. Of some plants, all plant parts from root to flower are used. Others develop their medicinal potency only in a specific part of the plant. Another distinction is whether you purchase these plants processed or pick them fresh and process them yourself. The latter is not always possible. Medicinal plants such as ginseng or echinacea (sunflower), for example, are not found in the wild in all countries.
Processing and dosage depend on the specific plant. Medicinal plants can be used as teas, brews or ointments. There are processed varieties on the market, so the plant's ingredients can also be purchased in the form of tablets, candies, juices or creams.
The application may be internal or external. Some are suitable for infusion, washing or bathing. Others are most effective in the form of herbal teas or drops. For certain medicinal plants such as nettle or sage, a tea made from fresh leaves is more effective than dried leaves. For other plants, the active ingredient is released only by drying or crushing the plant parts.
