Salvia Militorrhiza, or Danshen, is a traditional Asian herbal medication for circulatory ailments. It has shown efficacy in treating various markers of heart health, and is typically seen as a very heart healthy herb.
Danshen works through a few primary ingredients, which all work synergistically on various parameters of heart and circulatory health.
It is the largest herbal market in China, and is commonly sold as dripping pills (to be absorbed under the tongue) or as oral tablets. Both are effective, but the dripping pills appear to provide more of the active ingredients.
