Flu is a type of exogenous disease that stems from pathogenic influences, affecting the primary functions of the lungs, presenting major clinical manifestations such as nasal congestion, sneezing, headache, chills and fever, and fatigue.
Due to the differences in climate and individual’s constitution, there are various clinically-proven symptoms like pathogenic wind-cold and pathogenic wind-heat, pathogenic heat-dampness. During the course of diseases, symptoms can be interchanged, transformed, and intertwined. Individuals who are older/weaker/post-illness/postnatal, repeatedly catching the flu will be different compared to the general population.
The prognosis is generally positive. However, for certain groups of people, the flu can trigger or worsen other chronic ailments and potentially lead to serious repercussions. This group includes the elderly, the young, and those with weaker immune systems.
They should also cater to their outfits according to weather changes i.e. wearing thicker clothing/more layers in cold weather and thinner/fewer layers in hot weather. Moreover, individuals should avoid close contact with flu patients to protect themselves from the virus.
During the flu season, preventive medication can largely reduce the probability of contracting the virus. Effective medication includes Guan Zhong(Dryopteris crassirhizoma Nakai), Da Qing Ye(Folium Isatidis), Ban Lan Gen(Radix Isatidis), Ya Zhi Cao(Herba Commelinae), Huo Xiang(Herba Pogostemonis), Pei Lan(Herba Eupatorii), Bo He(Herba Menthae), Jing Jie(Herba Schizonepetae).
However, the type of medication is dependent on seasonal and weather changes.
Spring and Winter: Guan Zhong(Dryopteris crassirhizoma Nakai), Zi Su(Folium Perillae), Jing Jie(Herba Schizonepetae)
Summer: Huo Xiang(Herba Pogostemonis), Pei Lan(Herba Eupatorii), Bo He(Herba Menthae)
Fall: Ban Lan Gen(Radix Isatidis), Da Qing Ye(Folium Isatidis), Ju Hua(Flos Chrysanthemi), Jin Yin Hua(Flos Lonicerae)
Other day-to-day ingredients that are useful in preventing the flu are onions, garlic, and vinegar.
When down with the virus, individuals should have plenty of rest, consume more water, and tailor their diet to consist of more vegetarian and watery dishes. Individuals should also avoid greasy food that is difficult to digest.
Resting areas should be well ventilated but not exposed to direct wind.
When concocting medication, the time taken should be short to preserve the nutritional value of the herbs.
After consuming the medication, if an individual is not perspiring, he/she can consume hot porridge or use a blanket to promote perspiration. Lastly, it is important to change into a set of clean and dry clothing to prevent contracting the flu again.
