G. j. var. Thunberg

Geum japonicum is a yellow-flowering perennial plant native to North America and East Asia, especially Japan. It may be synonymous with Geum macrophyllum, the North American flower. As a traditional herbal remedy it is known as an astringent and used in poultices.[1] However, in recent years, the Thunberg variant has received attention for other possible medical uses.

With regard to muscular recovery, an extract has been found to help muscles recover following "severe injury",[2] to reduce myocardial infarct size by 35-45% when administered following a heart attack,[3] and to inhibit apoptosis.[4] It also has possible anti-viral properties,[5] including action against HIV [6] and HSV.[7] Action against tumors has also been noted.[8]
