Katarantus – a guest from Africa

Katarantus (lochner, pink periwinkle, rose vinca) is an ornamental shrub from the kutrovy family. The well-known cultivated plants oleander and periwinkle also belong to this family. The vast majority of species of this family (and there are about 2000 of 200 genera) are concentrated in tropical countries of both hemispheres. The homeland of the catharanthus is tropical Africa. Among kutrovye there are many ornamental plants with beautiful, often fragrant flowers, but they are all cultivated within the tropics. Many species are of significant economic importance in the tropics: some were introduced into cultivation for the sake of edible fruits, others for the production of natural rubber, the manufacture of coarse fabrics, fishing tackle, and ropes.

Medicinal properties of catharanthus

They are also used for the manufacture of medicines, as they are rich in alkaloids and other substances. For example, drugs such as reserpine and raunatin are derived from the poisonous rauwolfia serpentine; from the seeds of African strophanth, poisonous glycosite stofantin is obtained, which is part of drugs that support cardiac activity. The Indians impregnated their deadly arrows with strophanth poison. It is used for diseases of the heart muscles, the glycosides contained in oleander leaves (all parts of this plant are poisonous).

Catharanthus is also used in tropical countries as a medicinal plant. It is used to prepare drugs Vinblastine and Vincristine, which are used in oncology.

All medicinal substances are isolated from these plants in a special way only at pharmaceutical enterprises.

The independent use of kutrovy, including catharanthus, is not recommended, as it can lead to dangerous consequences as a result of poisoning. Many kutrovye are poisonous, including such a plant as catharanthus.
