Researchers have found that taking 2.4 g of fish oil daily during the third trimester of pregnancy reduces the risk of asthma or wheeze in children by 30.7%. The effect was strongest for the children of mothers with the lowest blood levels of eicosapentaeonic acid (EPA) and docosahexaeonic acid (DHA) at the beginning of the study. For these mothers, the risk for asthma in offspring dropped by 54%. Fish oil supplementation also resulted in a 25% reduced risk of lower respiratory tract infections in children when compared to the control group.
In this study researchers investigated the effects of a herbal medicine Cordyceps sinensis for 3 months on patients with moderate-to-severe persistent asthma. The results showed a significant increase in Juniper’s Asthma Quality of Life Questionnaire scores and lung function compared with the control group. The expression levels of the inflammation markers IgE, ICAM-1, IL-4, and MMP-9 in the serum were decreased and IgG increased in the treatment group compared with the control group. The authors conclude ‘a formulation of Cordyceps sinensis improved the HR-QOL, asthma symptoms, lung function, and inflammatory profile of the patients with moderate-to-severe asthma’.
