Pharmacognostical, biochemical activities and zootechnical applications of Psidium guajava (Myrtaceae), plant with high medicinal value in tropical and subtropical parts of the World: A review

Abstract

In the search for new molecules capable of treating intestinal parasitosis with less risk in the short, medium and long term, the potential of medicinal plants is explored. Psidium guajava is plant used traditional medicine to treat gastrointestinal disorders and intestinal parasitosis. According to the synthesis of reviews presented here, very few studies have been devoted to the evaluation of anthelmintic activities of Psidium guajava. Psidium guajava has secondary metabolisms responsible for its demonstrated biological activities and reported medicinal uses. The leaves and fruits of Psidium guajava contain essential oils that know a great variation in the content of compounds. Geographic and edaphic conditions, and genetic factors are factors that influence the composition of essential oils. The direct consequence is the observation of several chemotypes of essential oils of Psidium guajava. Further studies are important to demonstrate the efficacy of Psidium guajava in the treatment of intestinal parasitosis.
