RODRIGUEZ RIVAS, Migdalia et al. Acción antiasmática del Aloe vera en pacientes. Rev Cubana Plant Med [online]. 2004, vol.9, n.1. ISSN 1028-4796.

A stepwise study was designed and developed in the province of Santa Clara for some years to assess the usefulness of Aloe vera L. in the treatment of bronchial asthma. In a first stage, the anti-asthmatic effect of the syrup of this plant was analyzed at different concentrations and it was compared with a placebo syrup. Through a clinical study and by respiratory indicators it was proved the symptomatic improvement and the enhancement of the functional patterns in the patients that received the medicinal syrup 50 %, compared with those that were administered placebo. A second stage of the research consisted in assessing the protective effect of the Aloe syrup 50 % in the bronchial hyperreactivity induced by carbacholine. The third stage of the research evaluated the effect of nebulization prepared from the extract of Aloe vera and it was demonstrated its protection against the bronchial hyperreactivity to carbacholine. These results were compared with those of sodic nedocromil and no significant differences were found. The undesirable effects were just a few. Only a mild laxative effect was reported among the patients that received syrup from the plant. Those patients that inhaled the extract, coughed when it was administered at flows over 3 or 4 liters per minute.
