Eastern Medicine for Prevention and Treatment of Flu

Here's the winter flu season again – more and more friends get sick, influenza is in the news, and on the minds of many people. As common as they sound – the truth is, the typical seasonal flu takes far more lives in the United States every year than some less common diseases (on which lots of attention and resources focus) ever have. 


The number of seasonal influenza-associated (i.e., seasonal flu-related) deaths varies from year to year because flu seasons often fluctuate in length and severity. In December 2016, CDC posted estimates of seasonal flu deaths from more recent seasons in the United States. CDC estimates that from 2010-2011 to 2013-2014, influenza-associated deaths in the United States ranged from a low of 12,000 (during 2011-2012) to a high of 56,000 (during 2012-2013). Death certificate data and weekly influenza virus surveillance information was used to estimate how many flu-related deaths occurred among people whose underlying cause of death on their death certificate included respiratory or circulatory causes.

Traditional Chinese medicine (TCM) and other Oriental medical practices have a long and successful history of treating and preventing winter colds and flu. The most common way that Western medicine offers for dealing with the potentially deadly complications of seasonal flu is to use vaccination. The potential risks of vaccines have been well documented. While vaccines have proven to prevent certain strains of the flu – one vaccine cannot prevent all variants of the disease, and a flu shot does absolutely nothing to prevent or lessen the severity of colds.

Oriental medicine, on the other hand, is designed to strengthen the immune system when it is at its most vulnerable – during the winter and flu season. Qi, when restored and strengthened, can prevent the acquisition of colds, flu, and other seasonal viral infections. In the TCM tradition, the symptoms of any flu are the result of pathogenic heat, cold, or dampness. Oriental medicine has an old tradition of using herbal medications to boost qi, and prevent these pathogens from gaining egress into the body. In fact, in China, school children are served herbal teas during flu season to prevent the spread of colds and flu.

Herbal Medications and Flu

Various herbal formulas are used in TCM to treat the different symptoms of the flu. Respiratory issues are treated with herbs such as Jiu ma huang (aka Chinese ephedra). Other treatments for the respiratory conditions associated with colds and flu used in China include an oral liquid called Shuanghuanglian, which is a formula made up of baikal skullcap root, honeysuckle, and forsythia.  For the digestive distress that is also often associated with flu, TCM suggests herbs in the family of Ge gen (radixpuerariae) and ageratum.
The fever that is common to viral infections such as colds and the flu, is believed in TCM to be caused by a Heat pathogen. Heat pathogens are traditionally and effectively treated in TCM with herbs such as Huang Lian (Coptis chinensis), which has specifically shown promise against influenza viruses in clinical trials.
It is interesting to note that viruses, such as those that cause colds and the flu, mutate rapidly. Western medicine traditionally develops ant-viral medications with a single active ingredient. TCM herbal medications use many ingredients, with individual practitioners often developing their own unique formulations. It is therefore much easier for mutated viruses to become resistant to traditional pharmaceuticals, then to the herbal elixirs of TCM.  

To really customize an herbal formula to what stage of a cold you are at and your constitution, I would recommend an in-person consult. But even if you can’t see a quality Chinese Medicine practitioner as we at WeCare Holistic sometimes help recommend in person, there are some general nutrient and herbal formulas that are balanced enough to be safe and effective in all generally healthy adults who are trying to fend off impending coughing and sneezing.  

Prevention First

Hands down, the best way to fight a cold or flu is to not get sick in the first place!

It goes without saying that practicing good hygiene is the first step – wash your hands with hot water and soap and cover your nose and mouth when you cough or sneeze. Eating a nutrient-dense diet, getting plenty of sleep, and regular exercise can also help keep your immune system strong so that you effortlessly fight off anything that comes your way.
But Chinese herbs can be a secret weapon in preventing colds, too. Herbs can help strengthen our immune systems and fight off colds before they take root.

Diagnosis of Cold and Flu

According to the different signs and symptoms, cold and flu can be classified into two main types and other less common ones according to TCM disharmony patterns.


1. Wind-Heat Type Cold and Flu 


This type is mainly caused by influence of both wind and heat evils. It is commonly seen in the spring and summer and tends to be more prevalent in the southern China region, because of a relatively hot climate. Nasal congestion, sneezing and a minor fear of wind blowing are general signs of an attack of a wind evil in cold and flu. These symptoms are usually thought of as an exterior syndrome of the body. 

Heat evils are generally characterized by yellow and thick body secretions. For example, a fever or high fever, sweating, sneezing with thick nasal secretions and a cough with thick phlegm may indicate an influence of a heat evil. In the case of wind-heat invasion, a thin yellow tongue coating and a rapid and floating pulse also indicate an exterior syndrome pattern. Since wind-heat can easily consume body fluids, individuals may experience a dry mouth and sore throat.

2. Wind-Cold Type Cold and Flu


This type is mainly caused by an influence of both wind and cold evils. It may be more prevalent in winter or in cold environments such as those with air-conditioning. Cold evils lead to feeling cold, making things contract and obstructing the flow of qi. Therefore, a fear of cold and an absence of sweating are major signs of cold invasion. 

Cold evils are also often related to clear body secretions, nasal congestion, sneezing with clear discharge, absence of fever or a low-grade fever and a cough with white and thin phlegm. A thin white tongue coating and a floating and tense pulse are common signs of cold evils. As cold evils obstruct the flow of protective qi in the skin and muscles, individuals may often experience myalgia (muscular pain).

3. Other Type 
In addition to wind-heat and wind-cold type cold and flu, there are other types caused by evils such as dampness and summer-heat evils. It may likely be accompanied by some other disharmony patterns such as a qi deficiency and or yin deficiency too. Typically, they occur in summer. 

Individuals with the cold and flu caused by Dampness pathogens will constantly feel the presence of Heat in the body but have no significant increase in body temperature. Other symptoms include constant thirst with mild sweating; fatigue; lethargy and an occasional chest tightness. 

Damp-heat type is mostly seen, which presents with a fever, slight aversion to cold, absent or only mild sweating, a heavy and distending pain in the head, chest oppression, thirst, nausea, limb soreness or pain and scanty and yellowish urine.



Home Remedies 

My favorite home remedies for preventing wind-cold type of cold and flu are ginger brown sugar hot drink, and “five tiger soup”. Treatment methods such as herbal remedy, acupuncture or cupping are usually employed to ease the wind-cold symptoms. Herbs used will usually be warm in nature, such as Folium Perillae (Zi Su Ye, 紫苏叶) and Ramulus Cinnamomi (Gui Zhi, 桂枝), which aim to induce sweating to dispel the cold and wind pathogenic factors from the body.

For wind-heat type of cold and flu, warm chamomile and peppermint tea would be naturally healing. Treatments are aimed at expelling out the heat and cooling the body. Examples of herbs which are used include Fructus Forsythiae (lian qiao, 连翘) and Flos Lonicera (honeysuckle flower, 金银花). 

Note: For Chinese readers, I have discussed the recipe details in our WeChat post about cold and flu.


For ready-to-eat products, an American TCM practitioner’s preferred formula for taking throughout cold and flu season to strengthen the immune system is Yu Ping Feng Wan. This traditional Chinese formula contains lots of Astragalus, an herb which helps to increase circulating white blood cell counts and increases cytokines in our immune system that help ward off viral infections. Depending on the brand and concentration of the formula, and the dose for adults is sometimes 2 tabs 2-3 times daily through cold and flu season.

What If I’m Already Sick? 


With any Chinese Medicine formula, the quicker you start to take it, the better results you can expect. Personally, I will sometimes take a few doses of the herbal formulas for the first stage of a cold if I have had significant exposure to someone who is currently sick, just to make sure I don’t come down with the same thing!

But even if you don’t catch it before symptoms set in, the sooner you start treatment, the faster you’ll feel better.

But I know what you’re thinking – the last thing you want to do when you already feel bad from a cold (and maybe have a spouse with the man-flu and kids who need your attention, too) is try and decipher labels at a Chinese herb shop without a Chinese friend who knows about this like me! That’s why that practitioner recommend keeping some herbal formulas on hand during the winter months. These are tablets that you can keep in the cupboard, just like you would a bottle of cold syrup. That way, when a cold or flu strikes, you’re already prepared.

Contact us at WeCareHolistic.com and leave what you would like to get. If (most often) your symptoms can be solved simply by utilizing ingredients in the nearby grocery store if not your fridge, we will let you know the recipe’s too.


It should be noted here that a high fever in any type of cold and flu, especially one that is persistent for more than eight hours and is not responding to either Chinese or Western medicine should be reported to your health care professional to be evaluated.
