3 medicinal plants for fighting asthma attacks

Asthma On this, World Asthma Day, the World Health Organisation (WHO) reminds us that 235 million people across the globe are affected by this chronic disease 1. Contrary to popular belief, it can develop at any age, manifesting as asthma attacks in which the sufferer has difficulty breathing. These attacks can be triggered by various factors such as atmospheric allergens, tobacco smoke, physical exercise or even intense emotion. While the precise cause of asthma is not yet fully established, a number of therapeutic options have been developed, including natural remedies. Here we look at three medicinal plants that can be useful in preventing or treating asthma attacks.

Desmodium adscendens, a plant traditionally used as a remedy for asthma

Beneficial properties for fighting asthma attacks
Though little-known in Europe, the medicinal plant Desmodium adscendens is widely-used for treating asthma in Ghana, Africa. Several studies have also confirmed its therapeutic benefits. One such study conducted in the 1980s highlighted the plant’s anti-anaphylactic properties2 - in other words, its ability to reduce the anaphylactic reactions responsible for asthma attacks. Scientists have also shown that oral administration of Desmodium adscendens may reduce levels of the substances released in asthma.

Active principles with anti-asthma properties
Published in1984 in the Journal of Ethnopharmacology, the results of this first study were later expanded in research conducted in the 2000s. In 2011, a team of scientists succeeded in identifying several active principles in Desmodium adscendens: triterpenoid saponins, phenylethylamines and indole-3-alkyl amines 3. Analysis of these compounds revealed a number of health-beneficial properties including an anti-asthma effect. Additional studies are still in progress but these recent results already provide confirmation of the therapeutic potential of Desmodium adscendens. The benefits of this medicinal plant can be obtained in the form of dietary supplements, including a liquid extract calledDesmo Forte™, available from the Supersmart catalogue.

Ecklonia cava, an alga for combatting asthmatic reactions

The benefits of supplementing with Ecklonia cava
The subject of increasing research over the last few years, algae may also offer benefits to asthma sufferers, with recent studies identifying certain algae as able to inhibit asthmatic reactions. In a mouse study conducted in 2008, for example, scientists investigated the asthma-preventive effects of supplementation with the brown alga Ecklonia cava4. In order to simulate an asthma attack, the researchers exposed the mice to a protein called ovalbumin, triggering various reactions characteristic of an asthma attack, such as:
  • - increased numbers of immune system cells called eosinophils in bronchoalveolar lavage fluid ;
  • - a marked and sudden influx of inflammatory cells in the lungs, specifically around blood vessels and airways;
  • - a narrowing of the airways;
  • - development of hyper-responsiveness in the airways;
  • - the appearance of several immune molecules in the bronchoalveolar lavage fluid: TNF-alpha and cytokines (IL-4 and IL-5)
  • - the presence in serum of the specific antibody immunoglobulin E or IgE.
The study’s results indicate that supplementation with Ecklonia cava may prove particularly effective at treating asthmatic reactions. Based on these promising findings, dietary supplements have been formulated from this alga, including the product offered by Supersmart: Ecklonia cava.

Therapeutic potential of Ecklonia cava
This particular alga may have other medical applications over and above its efficacy against asthmatic reactions. Scientists have shown that an Ecklonia cava-based treatment reduced concentrations of matrix metalloproteinase-9 (MMP-9), a marker of inflammation observed in several diseases including atherosclerosis. This alga’s therapeutic potential is actually discussed in our articles: ‘A plan of attack against atherosclerosis’ and ‘Put an end to chronic inflammation’.

Coleus Forskohlii, an Ayurvedic herb for preventing asthma attacks

Used in traditional Indian medicine, the Ayurvedic herb Coleus Forskohlii has attracted scientific interest for its potential in combatting asthma attacks. This medicinal herb contains a powerful active principle called forskolin. Forskolin has been extensively-studied by a Mexican research team whose findings were published in 2006 and 2010 in the Journal of International Medical Research5,6. In the first of their studies, the researchers compared the effects of forskolin with those of sodium cromoglicate, a drug used to treat allergies. For six months, they monitored several patients with varying degrees of persistent asthma, some of whom were given a daily 10mg dose of forskolin, while others were treated with sodium cromoglicate inhalation. By the end of the study, the forskolin-supplemented patients were found to have suffered fewer asthma attacks than those treated with sodium cromoglicate. Encouraged by these preliminary results, the researchers continued their investigations into forskolin. In 2010, they published a comparison of the effects of this active principle with those of the asthma drug beclomethasone. In this two-month study, in which 60 asthma patients were either given 10mg forskolin a day, or treated with beclomethasone inhalation, the efficacy of forskolin in preventing asthma attacks was again confirmed. As a result of this research, forskolin supplements have been developed with the aim of making daily life for asthmatics a little easier. Among the products available is a supplement offered by Supersmart which has been developed from a natural extract of Coleus forskohlii standardised to 10% forskolin.
