Key TCM concepts behind red sage roots (Dan Shen)'s properties

In Traditional Chinese Medicine (TCM), red sage roots are plants that belong to the 'Herbs that invigorate the Blood' category. Like the name indicates these herbs tend to stimulate the Blood flow. In TCM they're used to help the circulation of Blood in cardiovascular conditions or menstrual irregularities as well as to treat acute pains caused by Blood Stagnation. They can also be used to treat Blood Stasis in the case of certain tumors, cysts and hardened clots.

Furthermore red sage roots are plants that are Cool in nature. This means that red sage roots tend to help people who have too much "heat" in their body, although with less effect than a plant that would be Cold in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much heat in their body are said to either have a Yang excess (because Yang is Hot in nature) or a Yin deficiency (Yin is Cold in Nature). Depending on your condition red sage roots can help restore a harmonious balance between Yin and Yang.

Red sage roots also taste Bitter. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Bitter ingredients like red sage roots tend to have a cleansing action on the body by clearing heat, drying dampness and promoting elimination via urination or bowel movements.

The tastes of ingredients in TCM also determine what organs and meridians they target. As such red sage roots are thought to target the Heart and the Liver. In addition to regulating blood flow, in TCM the Heart is believed to be the store of the "spirit" which basically refers to someone's vitality. The Liver on the other hand is often referred as the body's "general" because it is in charge of regulating the movements of Qi and body fluids. It also takes a leading role in balancing our emotions.

Research on red sage roots(Dan Shen)

60 eligible randomized controlled trials indicate that Danshen dripping pill is apparently more effective than isosorbide dinitrate in treating angina pectoris.1

Administration of Danshen Chuanxiongqin Injection before percutaneous coronary intervention could effectively inhibit the activation of platelets, improve post-operative myocardial blood perfusion, and lower the incidence of the myocardial damage.2

Salvia miltiorrhiza hydrophilic extract has a potential protective effect on the development of diabetic cardiovascular disease.3

Fufang Danshen (Salvia miltiorrhiza) extract reduced systolic blood pressure and pulse rate, and was well tolerated in patients with hypertension.4
