What does it do?
In Traditional Chinese Medicine (TCM), our body is vulnerable to attacks of
pathogenic influences such as cold, wind, and dampness. The attacks first invade the peripheral. When it occurs at the respiratory
track, the body may react with symptoms like fever, cough, and headache. When it occurs at the
digestive track, the body may react with throwing up and diarrhea. The pathogenic influences in modern medical terms
belong to bacteria and viruses (e. g., cold viruses, rotaviruses, and Escherichia coli).
In hot and humid weather, bacteria and viruses grow and spread easily. Foods get more easily contaminated
and spoiled. Temperatures vary significantly between day and night. People like to stay in air
conditioned rooms, sleep without cover, drink a lot of cold water.
These factors may render people more susceptible to the attacks of cold, wind, and dampness.
As a result, people develop a set of symptoms that may be variably called summer colds, stomach flu, or heat stroke.
Summer colds at first have some symptoms of a common cold like chill, fever, headache, cough, and running nose.
Moreover, summer colds have symptoms of gastrointestinal upset marked by nausea, vomiting, diarrhea, abdominal pain,
loss of appetite, and bloating. When the gastrointestinal symptoms like diarrhea dominate, the disorder is more often called stomach flu,
or formally gastroenteritis. When the symptoms are clearly caused by a prolonged exposure to a hot, humid environment,
the disorder is often refered to heat stroke.
Huo Xiang Zheng Qi Wan is a primary herbal formula in TCM that addresses the above disorders. It has
properties that separately take care of the aspect of common colds and that of gatrointestinal discomfort.
It acts to disperse cold and dampness to remove external symptoms and harmonize the stomach. For this reason,
it is a household Chinese medicine in China for gastrointestinal discomfort and widely used in traveling
and outdoor activities, specially during the summer time.
Huo Xiang Zheng Qi Wan is indicated in China Pharmacopoeia1 to relieve superficies with diaphoresis
and eliminate dampness, and regulate Qi flow to promote digestion.† The herbal formula is used for both exterior
invasion of wind cold and interior injury of stagnated dampness marked by aversion to cold, fever,
headache, chest distress, abdominal flatulence, nausea, vomiting, anorexia, borborygmus, diarrhea,
tastelessness in the mouth, and whitish and greasy lingual fur, etc.
