Astragalus and Sage for Long COVID

​Fatigue and brain fog are two of the most challenging symptoms of long COVID.

This study gave a combination of astragalus and Salvia miltiorrhiza, also known as Chinese sage or danshen, to 49 people with long COVID who were experiencing severe fatigue or brain fog. Chinese sage is a close relative of the western herb sage.

After 4 weeks, there was a significant improvement of about 50% in both physical and mental fatigue. People rated their fatigue as improved by 54% and their brain fog by 52%. They also reported that their quality of life improved by 47%.

The researchers called these improvements “significant” and “radical.”
