Effectiveness and Safety of Oral Cordyceps sinensis on Stable COPD of GOLD Stages 2–3: Systematic Review and Meta-Analysis

Abstract EN

Cordyceps sinensis (CS) is a complementary medicine used for Chronic Obstructive Pulmonary Disease (COPD) of Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages 2-3.

Many randomized controlled trials have been conducted to evaluate the effect of CS alone or in combination with other herbs on stable COPD.

To provide a synthesis of the evidence, we searched nine major electronic databases for randomized controlled trials on CS published before 21st December 2016.

Fifteen interventional studies, including 1,238 participants, met the inclusion criteria.

Meta-analysis showed that both CS preparations and CS formulae showed the potential benefits in lung function, exercise endurance, life quality, and improvement of symptoms.

No serious adverse events were reported.

So CS may be a promising treatment for patients with stable COPD of GOLD stages 2-3.

No studies were placebo-controlled or of high methodological quality, which limits the conclusions.
