Key TCM concepts behind arisaema (Tian Nan Xing)'s properties

In Traditional Chinese Medicine (TCM), arisaema are plants that belong to the 'Warm herbs that transform Phlegm and stop Cough' category. In TCM Phlegm is a condition of Stagnation of Fluids which tends to start in the Spleen and then goes to the Lungs. If this overly accumulates it thickens and becomes pathological Phlegm. Phlegm, being a form of Stagnation, often starts as being Cool and transforms to Hot as the condition progresses.

Depending on your condition arisaema can help restore a harmonious balance between Yin and Yang.
