Autumn has arrived, and many people have put foot soaking and health preservation on their agenda. Recently, a netizen stated that due to physical discomfort, traditional Chinese medicine diagnosed him with poor spleen and stomach, and heavy dampness. He also instructed him to use Huoxiang Zhengqi Water to soak his feet and dispel dampness. Netizens have followed suit and also used Huoxiang Zhengqi water to foam their feet. However, many netizens have expressed that "after soaking, it directly ignites, causing sore throat and acne", "after personal testing, it spreads thin", "I soaked my feet but my shoulders and neck feel cold"... Professor Wu Zhiyong from the Traditional Chinese Medicine Department of Southern Hospital said that for people with damp and hot constitution, reasonable use of Huoxiang Zhengqi Water to soak their feet can indeed bring heat clearing and dampness removing effects, but not everyone is suitable. Huoxiang Zhengqi Water is not a 'panacea'! These populations should be cautious. It is understood that as a well-known medicine, Huoxiang Zhengqi Water was originally formulated with Huoxiang Zhengqi Powder from the Song Dynasty's "Taiping Huimin He Ji Ju Fang". Wu Zhiyong introduced that this medicine has the effects of soothing the liver and regulating qi, promoting qi circulation, and resolving dampness. It can alleviate symptoms such as stomach bloating, loss of appetite, nausea and vomiting. It can be used for patients with gastrointestinal discomfort, mild indigestion, and mild diarrhea caused by enteritis, food poisoning, or damp heat. In addition, Huoxiang Zhengqi is also effective in treating pediatric diseases such as prickly heat, mosquito bites, and eczema. Reasonably using Huoxiang Zhengqi Water to soak feet can indeed bring about the effect of clearing heat and removing dampness, but not everyone is suitable. "Wu Zhiyong reminds that people with spleen and stomach deficiency cold constitution, yin deficiency constitution, and hot internal heat are not suitable for using Huoxiang Zhengqi Water. Huoxiang Zhengqi Water can easily cause gastrointestinal dysfunction and diarrhea symptoms in these populations, which may increase the body's dryness and heat sensation, exacerbating symptoms. It is worth mentioning that when using Huoxiang Zhengqi Water, be careful not to eat sweets. "Wu Zhiyong said that Huoxiang Zhengqi Water can relieve dampness, while sweet foods such as fruits and beverages can cause dampness. The interaction between the two will reduce the efficacy of Huoxiang Zhengqi Water. Long term soaking or foot soaking can cause overheating or harm. "A person's feet are like a tree's roots." It is understood that traditional Chinese medicine has always attached great importance to the exercise and maintenance of both feet. Wu Zhiyong introduced that soaking feet for 15 minutes every day can have a health effect. Soaking feet can promote blood circulation, regulate the function of various organs, enhance the endocrine system function, improve self-defense ability, and eliminate fatigue and tension. "Wu Zhiyong introduced that immersing both feet in hot water at 36 to 37 degrees Celsius will significantly alleviate headaches after 15-20 minutes. This is because the blood vessels in both feet dilate, causing blood to flow from the head to the feet, which can relatively reduce cerebral congestion and alleviate headaches. Wu Zhiyong reminds that although proper foot soaking is beneficial, it is also important to pay attention to the way you soak your feet. When on an empty stomach or after a meal, one cannot take a foot bath immediately. "He introduced that during the foot bath process, the body consumes a lot of calories. If the foot bath is taken immediately after a meal, due to the increase in temperature and the stimulation of hot water, the skin blood vessels will expand, and the blood in the digestive organs will be relatively reduced, thereby hindering the digestion and absorption of food. Long term soaking and overheating of foot soaking water can also be harmful. It is understood that soaking or showering in overheated water for too long can cause significant dilation of blood vessels in the body and limbs of elderly people, with a large amount of blood flowing to surrounding blood vessels, causing transient ischemia and symptoms such as dizziness, dizziness, and nausea,
