Wind is one of six climatic pathogenic factors (ie. a quality in the environment or climate which can cause disease) It is the predominant climatic factor in spring, but can also be a cause of disease in other seasons as well. The nature of Wind is yang and is a major factor involved in pathogens entering the body.
Wind’s nature is to rise and disperse and so its symptoms are more likely to manifest in the upper or superficial parts of the body, ie head, face or skin. Wind invasion symptoms can be dizziness, vertigo, itchy skin, common cold, tremors and spasms.
