Key TCM Concepts

In Traditional Chinese Medicine (TCM), Ma Chi Xian belongs to the 'Herbs that clear Heat and relieve Toxicity' category. Herbs in this category are used to clear inflammatory and infectious conditions, referred to as 'Internal Heat' in TCM. This is why most of the herbs in this category will have both antibacterial and antiviral properties. In TCM one has too much 'Internal Heat' in their body as a result of a deficiency of 'Yin' (which is Cold in nature, see our explanation on Yin and Yang) or, more commonly, an Excess of Yang (Hot in nature). Herbs that clear Heat and relieve Toxicity treat the latter while, at the same time, removing infectious toxins from the body. As such they tend to be Cold or Neutral in nature.

 

As suggested by its category Ma Chi Xian is Cold in nature. This means that Ma Chi Xian typically helps people who have too much 'Heat' in their body. 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 Ma Chi Xian can help restore a harmonious balance between Yin and Yang.

 

Ma Chi Xian also tastes Sour. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Sour ingredients like Ma Chi Xian helps with digestion and restrain abnormal discharges of Fluids from the body, such as diarrhea or heavy sweating.

 

The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Ma Chi Xian is thought to target the Large intestine and the Liver. In TCM the Large Intestine receives the "impure" parts of the digested food from the Small Intestine, absorbs the remaining fluids and excrete the remainder as feces. 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 the Body Fluids. It also takes a leading role in balancing our emotions.

Common Applications

Research Studies

Scientific research and clinical studies on Ma Chi Xian

Extracts of the aerial parts (dried leaves and stem) of Portulaca oleracea showed significant anti-inflammatory and analgesic effects. Results indicate Portulaca oleracea possesses some of the claimed traditional uses of the wild species in the relief of pain and inflammation.1

Portulaca oleracea has wound healing properties. Fresh homogenized crude aerial parts of Portulaca oleracea were applied on wounds and the results obtained indicated that they accelerated the wound healing process by decreasing the surface area of the wound and increasing the tensile strength.2
