Clearing heat, cooling blood and anti-inflammatory effect

Moutan has a slightly cold skin, and is directed to the heart and liver meridians. It is good at clearing away heat and toxins in the blood, and has good effects on fever, macules, and hematemesis caused by febrile diseases. Studies have shown that its active ingredient paeonol can inhibit the release of inflammatory factors (such as IL-6, TNF-α) and reduce tissue redness, swelling, heat and pain. In addition, peony bark has an inhibitory effect on common pathogenic bacteria such as Staphylococcus aureus and Streptococcus, and can be used to assist in the treatment of infectious diseases.

Promoting blood circulation and removing blood stasis and cardiovascular protection

The blood-activating effect of peony bark is related to its improvement of blood rheological properties, which can reduce blood viscosity, inhibit platelet aggregation, and thereby prevent thrombosis. Animal experiments show that peony bark extract can expand coronary arteries, increase blood supply to the myocardium, and have a certain effect on angina pectoris and arteriosclerosis. Clinically, it is often used in combination with Salvia miltiorrhiza and Ligusticum chuanxiong for the treatment of blood stasis-type coronary heart disease or irregular menstruation.

Clinical applications and precautions

Summary and Outlook

As a traditional Chinese medicine, peony bark has the dual effects of clearing away heat and activating blood circulation, and its pharmacological activity has been confirmed by some modern studies. In the future, more clinical trials are needed to clarify the dose-effect relationship and potential synergy to provide a basis for the development of new drugs. Reasonable use of peony bark can give full play to its unique advantages of "cooling blood without leaving blood stasis, activating blood without causing rash".
