Investigators from the Université de Lomé and Centre de Recherche Biomoléculaire Pietro Annigoni conducted an ethnobotanical survey to document plants used in Togolese traditional medicine to treat asthma in Togo’s southernmost Maritime Region, where the main ethnic groups are the Ewe, Ouatchi, Mina, Fon, and Adja people.
For their study, the team interviewed 121 traditional healers, who use clinical manifestations such as wheezing, coughing, difficulty in speaking, dyspnea, dry cough, sweating, and increased heart rate to diagnose the disease.
Writing in the African Journal of Traditional, Complementary and Alternative Medicines, Gbekley et al. document 98 plant species used in southern Togo to treat asthma, including Carica papaya, Cataranthus roseus, Eucalyptus camaldulensis, Piper guineense, Eucalyptus citriodora, Eucalyptus globules, and Euphorbia hirta. The team conducted a literature review to assess previous relevant ethnobotanical citations related to asthma, toxicity data, and screening reports for immunomodulatory activities.
From the introduction:
“Asthma is a chronic disease characterized by variable airflow limitation and/or airway hyper-reactivity with symptoms causally related to family history, environmental influences, exposure to viruses and allergens as examples. The high economic burden linked with asthma is associated primarily with health care costs, missed work or school days. The treatment of asthma in the modern medicine is based on the use of beta agonists, leukotriene modifiers and inhaled corticosteroids that allowed an acceptable control of the main symptoms. However, this therapy could not suppress all the symptoms although the better understanding of the pathophysiology of the disease. On the other hand, the requirement for daily inhalation with glucocorticoids is often a cause for patient discomfort, limiting the use of glucocorticoids in asthma therapy. In addition, the current therapy is not affordable for the patients in developing countries, who rely on the traditional medicine. Therefore, there is a significant need for new medications for the treatment of asthma that are highly efficacious, with low cost, easily managed and with few adverse effects. In the search for new medications for asthma, plants through the traditional medicine are a credible alternative.”
The authors recommend further laboratory screenings to identify specific bioactive molecules that might be responsible for the reported therapeutic activities of these plant-derived medicines, and to investigate optimal dosages as well as possible side effects.
