In Traditional Chinese Medicine (TCM), there are six factors from the environment that contribute to illness and cause imbalances in our body.
- pathogenic wind 风
- pathogenic cold 寒
- pathogenic summer-heat 暑
- pathogenic dampness 湿
- pathogenic dryness 燥
- pathogenic heat (fire) 火
We, as part of nature, constantly have contact with these natural factors. Under normal conditions, our body can adapt to the environmental changes. However, if the harmonious relationship between human beings and nature is broken, an imbalanced body will become unable to adapt itself to the changes, leading to the occurrence of disease. Under such condition, the six natural climatic factors then become pathogenic factors. These factors can be either external (exogenous) or internal (endogenous) and both are interrelated. External factors are often the cause or triggers of internal factors.
Associated with Liver, Wood, Spring, and Yang "evil," wind tends to cause diseases most easily in Spring, but in other seasons wind also can cause disease.
Wind is characterized by the following features:
1. Wind floats: Because of its lightness, wind floats and disperses. It attacks the upper part of our body and skin first when it invades. Manifestations of evil wind can include headache, running nose, sweating and aversion to cold, etc.
2. Wind moves: Wind is mobile and the disease caused by it is also changing and occurs throughout the body, such as migratory pain of limbs, tremor, convulsion, spasm, and dizziness.
3. Wind changes: Wind tends to change, thus the disease caused by wind is often characterized by sudden onset, immediate transmission, and luckily, fast recovery, such as rubella.
4. Wind is often the leading cause of all diseases: Since it is easier for wind to attack the body, other exogenous factors often attach themselves to wind when they invade the body, frequently leading to wind-cold, wind-heat, wind-dampness, and wind-dryness syndrome.
Endogenous or internal wind is produced by the liver, so it is usually called "liver-wind". There are four factors responsible for the occurrence of endogenous wind：
- Extreme heat produces wind
- Excess liver-yang transforms into wind
- Yin-deficiency stirs wind
- Blood-deficiency stirs wind
These invasions often lead to diseases marked by convulsion, tremors, and spasms.
To recover from a Wind invasion, we need down-bearing, liver-friendly foods and herbs.
