Traditional Used:

Peristrophe roxburghiana is essentially a plant used in traditional Chinese medicine. It is believed to clear heat and resolve toxins, cool the blood and extinguish wind. It also dissipate stasis and disperse swelling. [1]

Respiratory Diseases

The plant has been advocated for use in the treatment of various respiratory conditions especially cough and haemoptysis. It is also used in the treatment of tuberculosis. [2]

Inflammatory Diseases

It is used to treat tonsillitis, sores in the mouth and tongue, swelling due to abscesses, knocks and falls, and scrofula. The anti-inflammatory activity renders it useful in the treatment of snake bites. [2]

Pre-Clinical Data


Antithrombotic activity

Hemorrheological parameters (hematocrit, fribrinogen level, plasma viscosity and apparent whole blood viscosity) are primary risk factors in ischaemic heart disease. The extract from P. roxburghiana showed ability to decrease effectively many hemorrheological parameters while at the same time was found to inhibit thrombus formation. [5] 

Antihypertensive activity

Extract of P. roxburghiana was found to have the ability to reduce high blood pressure in rats. At the same time it increases the levels of NO and NO-synthase in the serum and NO in urine. It also reduces the concentration of ET in serum and that of angiotensin II in the thoracic artery. Thus, the possible mechanism of the anti-renovascular hypertensive activity it through increasing NO in serum and decreasing angiotensin II in thoracic aorta. [6] [7]

Antioxidant activity

Fresh P. roxburghiana has 64% free polyphenols within its substance rendering it active as an antioxidant. It showed significant free radical scavenging activity (EC50 = 10) and LDL oxidation inhibition activity (IC50 = 34.2 [total] and 44.9 [free] too. [3]
