The 50 best medicinal plants, their effects and contraindications

Since ancient times, when medical knowledge about how our body works was very limited compared to today, different people used different remedies to relieve discomfort, pain or symptoms of certain diseases.

A large part of them were based on the use of the properties of medicinal plants, Whose knowledge has in many cases alleviated a great number of sufferings.

The various plants considered to be medicinal have continued to be used ever since, even today. However, it is important to keep in mind what effects they have on the body and how to use them, as well as the fact that their healing potential is limited. Throughout this article we will show you some of the herbal remedies that exist and some of their properties.

    What is a medicinal plant?

    We give the name of medicinal plant to any vegetable that has positive properties that they can be used directly or macerated or as an infusion in order to contribute to the restoration or improvement of the state of health of a subject suffering from any disease.

    The use of these substances has been known since ancient times, naming in the papyrus of Ebers (Egypt, circa 1550 BC) more than half a thousand medicinal plants. And with time and the observation of new species and varieties, we can find many more.

    The knowledge of why they were used and how to use them has been passed down from generation to generation and has gradually modernized to this day. In fact, although the use of herbal remedies seems a bit of the past, the truth is that according to the WHO, the percentage of the population that uses some type of herbal medicine is quite high. In many cases, we don’t even notice it, like when we take chamomile when our stomach hurts or we take a lime to relax.

    If in general the use of these plants can be beneficial, the truth is that it should be borne in mind that they have their limits: often the concentration of active ingredients is very low and their effects are more limited than other alternatives. Likewise, Caution should be exercised with possible interactions when consumed with medications (For example, you should see your doctor if you are using St. John’s Wort and antidepressants).

    The use of medicinal plants is not particularly regulated, so abuse can occur and possible drug interactions and other contraindications cannot be taken into account. And finally, and this is something we discussed above, the use of medicinal plants does not have a purely curative purpose: it should not replace consultation with the doctor or taking medication.
