Atividade dos medicamentos homeopáticos Atropa belladona, Carbo vegetabilis, Natrum muriaticum frente ao Aspergillus niger Tiegher

Abstract

The use of homeopathy or ultra dilutions has been of great value in agriculture. It is an effective social technology and has obtained results in the control of diseases. The sisal region, located in Bahia, has serious problems due to the red rot of the Sisal, caused by Aspergillus niger Tiegh, which causes economic damage to the culture and losses of large production areas. The culture of sisal (Agave sisalana Perrine) has both economic and social value and its main product is fiber. Sisal is the basis of family farming in the region, however the lack of management of culture. In this context, the objective in this work was to evaluate the antifungal potential of the homeopathic medicines Atropa beladona, Carbo vegetabilis, Natrum muriaticum against the A. niger that causes the red rot of the sisal. The experiment was carried out in the laboratory Phytochemistry and Microbiology of the Center of Agricultural, Environmental and Biological Sciences / CCAAB in the Federal University of the Recôncavo of the UFRB Bay, using the following medicines: Atropa belladona, Natrum muriaticum and Carbo vegetabilis, in the dynamizations 5 CH, 15CH, 30 and 45CH (Hahnemanian centesimal scale) and the control against A. niger in vitro. The parameters evaluated were mycelial growth (CrM); percentage of mycelial growth inhibition (PICM), mycelial growth rate index (IVCM) and sporulation (ES). The experimental delineation was completely randomized with 5 treatments and 20 repetitions and the results obtained were subjected to analysis of variance and regression. The results show in the mycelial growth there is no statistical difference for dynamization in each treatment. But numerically Carbo vegetabilis, the 45 CH invigoration further inhibited the mycelial growth of the fungus in 36.46%. In the number of spores each treatment there was statistical difference for the Carbo vegetabilis and the Atropa belladona, and for the Natrum muriaticum there was no statistical difference. The drugs tested in this experiment had potential in decreasing the number of spores of A. niger, indicating interference of the homeopathic medicine in the reproduction of the fungus, causing alteration in the dynamic biorhythm of the microorganism. It is concluded that in the mycelial growth there was no significant difference for thedynamization in each treatment. Among the dynamizations in relation to the treatments, Carbo vegetabilis 45 CH stands out in the inhibition of mycelial growth and less sporulation. The Natrum muraticum had no statistical difference. Atropa belladonna stimulated the number of spores in dynamization 5 and 45 CH.
