thanks for bringing this interesting herb up. It is known as Red Sage as well?
MedlinePlus Herbs and Supplements: Danshen (Salvia miltiorrhiza)
Danshen (Salvia miltiorrhiza) is widely used in traditional Chinese medicine (TCM), often in combination with other herbs. Remedies containing danshen are used traditionally to treat a diversity of ailments, particularly cardiac (heart) and vascular (blood vessel) disorders such as atherosclerosis ("hardening" of the arteries with cholesterol plaques) or blood clotting abnormalities.
The ability of danshen to "thin" the blood and reduce blood clotting is well documented, although the herb's purported ability to "invigorate" the blood or improve circulation has not been demonstrated in high-quality human trials. Constituents of the danshen root, particularly protocatechualdehyde and 3,4-dihydroxyphenyl-lactic acid, are believed to be responsible for its vascular effects. Because danshen can inhibit platelet aggregation and has been reported to potentiate (increase) the blood-thinning effects of warfarin, it should be avoided in patients with bleeding disorders, prior to some surgical procedures, or when taking anticoagulant (blood-thinning) drugs, herbs, or supplements.
In the mid-1980s, scientific interest was raised in danshen's possible cardiovascular benefits, particularly in patients with ischemic stroke or coronary artery disease/angina. More recent studies have focused on possible roles in liver disease (hepatitis and cirrhosis), and as an antioxidant. However, the available research in these areas largely consists of animal studies and small human trials of poor methodological quality. Therefore, firm evidence-based conclusions are not possible at this time about the effects of danshen for any medical condition.
A small amount of research in humans suggests that danshen may improve breathing and lessen cough and wheeze in patients with chronic asthmatic bronchitis. Better studies are needed that compare danshen with more proven treatments for this condition before a clear conclusion can be drawn.
Danshen may increase the risk of bleeding. This herb is reported to inhibit platelet aggregation and to increase the blood-thinning effects of warfarin in humans. Caution is advised in patients with bleeding disorders, taking drugs that may increase the risk of bleeding, or prior to some surgical procedures. Dosing adjustments may be necessary.
