7 Powerful Medicinal Plants and Their Uses

In herbalism (herbology or herbal medicine), the term “medicinal plant” refers to a plethora of diverse types of plants and the study and practice of using plants for therapeutic purposes.

The term “herb” is derived from the Latin word “herba”. Cognates include “hierba/yerba” in Spanish, “herbe” in French, and “herb” in English. Previously, the term was only applied to non-woody plants derived from trees and shrubs. These medicinal plants are also utilized for food, flavonoids, medicine, perfumery, and purification ceremonies. A “herb” is at present represented by any plant part, including a fruit, seed, stem, bark, flower, leaf, stigma, or root, as well as any non-woody species.

Medicinal plants are said to include a plethora of components that can be used to create pharmacopoeial, non-pharmacopoeial, or synthetic medications. Furthermore, some plants are seen as essential sources of nourishment, and as such, their therapeutic effects are promoted.

Herbs and plants can be processed and consumed in various ways, such as whole herbs, teas, syrups, essential oils, salves, ointments and capsules containing the extract of a raw herb or in pulverized or powdered form. Plant extracts range with the solvent used, the temperature at which the extract is boiled, and the duration of the extraction. Alcoholic extracts (tinctures), hot water extracts (tisanes), prolonged brewed extracts of plants, typically roots or bark (decoctions), types of vinegar (acetic acid extracts), and cold infusions of plants are all types of plant extracts (macerates).

The following will be given a short description of some of the most common herbs used that have represented a vital role in the development of human cultures worldwide. Nevertheless, the list is not confined only to these herbs and plants.

Allium sativum refers to cultivated garlic and not to Allium ursinum (wild garlic); therefore, it is not common in wild habitats.

Its origins are most likely in Central Asia or maybe northeastern Iran.

Allium sativum is a widely used bulb in the Alliacea (Amaryllidaceae) family. It is an aromatic herbaceous plant that is mostly used in southern Europe as a flavouring in a wide variety of raw and cooked meals. Garlic is an incredibly nutritious and health-promoting food, but because of its strong flavour, it is typically used in very little amounts as a flavouring in salads and cooked foods.

Nevertheless, a vast field of clinical studies indicates that garlic improves glucose metabolism for diabetes, slows the progress of arteriosclerosis, and reduces the incidence of recurrent heart attacks in myocardial infarct patients. The plant’s extract can be used as a fungicide. The juice is an exceptional antibacterial for treating wounds externally. 

Fresh bulbs are significantly more medicinally effective than preserved bulbs; prolonged storage greatly diminishes the antibacterial effectiveness.


The World Health Organization (WHO) approximates that around 80% of people worldwide use herbal medicines concerning general aspects of their primary health care. Over 21,000 plant species have the potential to be used as medicinal plants, according to the WHO.

Whereas most medicinal plants are harmless when used correctly according to customary ways, others are poisonous by origin. In addition, improper use (wrong plant parts, dose, frequency, mode of administration, preparation, etc.) or misuse might result in negative outcomes.
