Recent patents on biotechnology (2025) · Review
Some medicinal plants, notably Echinacea purpurea and Zingiber officinale, exhibit potential for adjuvant symptomatic therapy in respiratory conditions, such as chronic obstructive pulmonary disease (COPD), bronchitis, asthma, the common cold, cough, and whooping cough.
Based on meta-analysis showing significant HAM-A score reduction (p=0.0007) and RCT evidence at 125mg dose. High heterogeneity (I2=98%) in pooled analysis suggests variable response. Extract standardization affects bioavailability.
Based on systematic review evidence of HPA-axis modulation and adaptogenic properties. However, reviewers note that effects on HPA-axis activity in humans remain unclear and require more definitive research. Conservative estimates due to limited human trial data.
