Efikasi dan Keamanan Echinacea dalam Pengobatan Infeksi Saluran Pernapasan Atas

Acute Respiratory Infection (ARI) is a disease that attacks the respiratory system and is classified as an infectious disease. This disease can be caused by various types of microorganisms such as viruses, bacteria, or fungi, but most cases of ARI are caused by viral infections. ARI includes conditions such as the common cold, bronchitis, pharyngitis, and pneumonia. In developing countries, ARI is a leading cause of death, especially in children under the age of five. Lack of access to health services, poor sanitation, and malnutrition are factors that contribute to this condition. Therefore, efforts to prevent and treat ARI are crucial, both through conventional and alternative medicine. One herbal plant that has long been used in complementary therapy for ARI is Echinacea, which comes from the flowering plant Echinacea purpurea and is native to the United States. Echinacea is believed to have immunostimulant properties, meaning it can stimulate the immune system, thereby helping to prevent and accelerate the healing of upper respiratory tract infections. Several studies have shown that the use of Echinacea can reduce the duration and severity of ARI symptoms, as well as reduce the risk of recurrent infections. However, research findings on the effectiveness and safety of Echinacea continue to show significant variation. Some clinical trials report significant benefits, while others find no significant effect compared to placebo. Therefore, a systematic review aims to gather the latest evidence regarding the effectiveness and safety of Echinacea in the treatment and prevention of acute respiratory infections (ARI). This approach is expected to yield stronger and more reliable conclusions to support the use of Echinacea as a safe and effective alternative therapy.
