ABSTRACT
The paper is a review of the literature on the ethnobotanical, chemical and pharmacological aspects of the species Cissampelos sympodialis Eichler, Menispermaceae, in order to assess its potential for the treatment of asthma. The aqueous infusion from the leaves of this Brazilian plant is used in the traditional medicine for the treatment of respiratory conditions, including colds, bronchitis and asthma. A multidisciplinary approach has led to the elucidation of the main chemical biomarkers and of the mechanism of action of the extract and its isolated constituents in animal models of inflammation and asthma. A comprehensive review of the literature on the species and its related chemical constituents was conducted using Pubmed, Web of Sciences, Lilacs, SciFinder, as well as conference proceedings. Retrieved literature data demonstrates that the aqueous fraction of the ethanolic extract from the leaves exerts an immunomodulatory activity in different animal models of asthma. This include an increase in the levels of anti-inflammatory cytokines, a decrease in the production of antigen-specific immunoglobulin, a decrease in mucus production and deposition in the airways, and a direct bronchodilator activity. These preclinical results clearly demonstrate the potential of this species for the treatment of asthma and points to the need for well-designed clinical trials to finally validate the traditional use of this herbal medicine.
