The effects of Chinese Yam

This study looked at whether a traditional herbal blend made from Chinese yam and epimedium could help people with moderate to severe chronic obstructive pulmonary disease (COPD) breathe more easily and improve their daily quality of life.

People with COPD were split into two groups. One group continued their usual medical treatment and also took the herbal mixture, while the other group received a placebo. Researchers tracked breathing difficulty, physical strength, body condition, and overall quality of life over one and three months.

The results showed that people taking the Chinese yam–epimedium mixture experienced less shortness of breath, better breathing comfort, and improved quality of life compared to those taking the placebo. After three months, participants in the herbal group were also able to walk farther in a six-minute walking test, showing improved exercise tolerance.

In simple terms, adding this herbal mixture to standard COPD treatment helped patients breathe easier, move more comfortably, and feel better overall. The study suggests that Chinese yam and epimedium may be a helpful supportive therapy for people living with stable COPD.
