Botanical Nomenclature. What are medicinal plants and to serve?
Medicinal plants are all plants that contain, in one of its organs, active ingredients, which, administered in sufficient doses, produces curative effects on diseases of men and animals in general.
Is estimated that about 260,000 plant species are known at present, of which 10% can be considered medicinal plants, ie, are contained in the herbal medical treatises, modern and past, to show some use.
Obviously, especially in equatorial regions, the proportions of medicinal plant species may vary considerably from this figure, since is not even known the whole flora.
Medicinal plants can cover practically all botanical nomenclature from herbaceous plants such as mint up trees like avocado and mango, finding substances with therapeutic effects on all parts of the plant.
