Treating the Common Cold, Influenza, and other acute viral infections
By John Staversky, certified clinical herbalist
Introduction — A Bit of History
Traditional Chinese Medicine (TCM) theory developed slowly over thousands of years in China. First came the concepts (out of Chinese culture at large) that undergird how they thought about the relationship between heath and nature. For example:
- The Tao is the natural way of the universe and that healthy living flows out of this awareness of natural processes
- The complementary balancing nature of Ying and Yang
- The web of relationships among the 5 elements of nature (air, water, fire, earth, and metal) and their correspondences with a wide variety of aspects of life (e.g. emotions, health, colors, the seasons, the directions of the compass)
In fact, the very idea that the processes of the body follow certain natural rules and that health comes out of an understanding of the rules of living had already been codified by about 300 BC in a book called the Nei Jing (The Yellow Emperor’s Classic of Medicine). But the first clinical discussion of health and disease came around the end of the Han Dynasty (c. 220 AD) in a book called the Shang Han Lun (Treatise on Cold Damage Diseases) compiled by Zhang Zhongling. In this work, the author describes an etiological theory of how one gets sick and then discusses a number of different herbal formulas for curing the patients he treats.
At its most basic level, one gets sick when an external pathogenic influence (referred to in TCM as wind, cold, damp, heat, and/or summer heat) invades the exterior layers of the body. The Wind is said to strike, and this Wind carries with it one of the other four “pernicious influences” into the exterior layers of the body. The Shang Han Lun, then, focused on attacks of Wind-Cold (given the cool, damp climate of the part of China where this theory developed). In a Wind-Cold attack, the symptoms we see are those we associate in modern times with the early stages of the common cold: the runny/stuffy nose, low-grade fever, body aches, and sore throat.
What happens next, according to TCM theory, depends on the ability of the body’s Wei (Defensive) Qi to expel the pathogen while it is still in the exterior layer of the body. If the Wei Qi is stronger than the invading pathogen, then the pathogen is vented out of the body and the patient does not get any worse. But on the other hand of the Wei Qi is weaker relative to the strength of the invading pathogen, then the pathogen sinks down into the interior of the body and it can be said that the Wind-Cold has turned to Wind-Heat. Wind-Heat (for the purpose of this discussion) is best thought of as the array of symptoms one shows when a cold settles in: low-grade fever, sore throat, body aches, and a dry cough.
So this theory of external disease put forth in the Shang Han Lun—that a pathogen invades from the outside and makes you sick (i.e. a Wind-Cold invasion)—existed in China for a very long time as the standard. But remember again that it developed in northerly climes where it is relatively cold and damp. So although people might have had the chills, runny nose, and lethargy characteristic of Wind-Cold, it would take days for the pathogenic influence to sink to the interior of the body to produce the more severe symptomology associated with Wind-Heat (this is another way of saying that because of the nature of their geography and climate, colds generally took a long time to “heat up” and turn into turn into the “flu”).
So through China’s long history (as their medical theory developed), diseases characterized by excess heat were not all that common; and when they did occur, they tended to start out cold, stay cold for days, turning hot only over a long period of time. So there just was not a great emphasis in TCM disease theory (based out of the Shang Han Lun) on “warm” diseases (or the herbs that specifically dealt with them).
But a new theoretical approach to deal with “warm pathogen diseases” (diseases that hit hard, fast, and above all “hot”) crystalized in the 18th century as new diseases appeared. These diseases (like diphtheria, malaria, and others of microbial origin characterized by acute, rapid on-set and burning fevers) did not start out relatively mild and “heat up” over time– instead they tended to hit communities hard and fast and create epidemics. The appearance of these new kinds of sicknesses and disease epidemics eventually led to a theory of Warm diseases—called the Wen Bing disease theory. This theory of warm diseases focused on dealing with invading pathogens that were so virulent that they quickly overwhelmed the body’s Wei Qi (moving quickly through the exterior layers of the body) and went straight to the interior where they created an excess of toxic heat. In dealing with these types of diseases, the physician’s goal emphasizes “clearing heat and resolving toxins”. Many of the herbs that clear heat and resolve toxins (and the formulas they comprise) were discovered/re-discovered and emphasized during this period of history.
Many more herbs that clear heat and resolve toxins have been discovered since the 1950’s when the Maoist government sent medical personnel throughout the length and breadth of China to find obscure herbs that the villagers in the countryside knew about. They brought this information back, and slowly but surely it has been incorporated into the contemporary practice of Traditional Chinese Medicine. This has led to the creation of wholly new formulas (e.g. Gan Mao Ling (featured below)) as well as to the modifications of others that have their origins in the Wen Bing movement.
The Formulas
The point of the history lesson above is to explain that there are two basic strategies for dealing with diseases that originate from exterior pathenogenic influences invading the body. One can either:
- Address the infection/invasion while it is still in the exterior layers of the body, in which case the treatment strategy is called Release Exterior; or
- Deal directly with microbial invasions that are creating imbalance (i.e. toxic heat) within the interior of the body. In this case, the treatment strategy is to Clear Heat and Resolve Toxins.
In this blog post, we will look at eight different Chinese herbal formulas that use these two treatment strategies to address sickness caused by Wind-Heat (viral) attacks. In the clinic these formulas are most commonly used in treating colds and flu, although they do have wider applicability to address other viral conditions.
The first two formulas we will look at in this article are Sang Ju Yin Wan (Clear Wind Heat Teapills) and Yin Qiao. They address the earliest stages of a Wind-Heat attack via the treatment strategy of releasing the exterior—that is, venting the external pathogen before it has a chance to sink down into the interior.
The next two formulas address acute viral infections that have started sinking down into the interior layers of the body to varying degrees; they are: Gan Mao Ling and Zhong Gan Ling. These formulas, while still venting the exterior to a lesser degree than Sang Ju Yin and Yin Qiao, shift the focus toward using anti-viral herbs to eliminate the pathogens from the interior (referred to in TCM as the function of Clear Heat/Resolve Toxins).
The last group of formulas to be addressed in this article are excellent Clear Heat/Resolve Toxin formulas that address other interior viral infections/conditions not necessarily related to the upper respiratory tract. These are Chuan Xin Lian Wan, Ban Len Gen Wan, Pu Ji Xiao Du Yin (Universal Benefit Teapills) and Wu Wei Xiao Du Wan (Five Flavor Teapills).
Group 1: Sang Ju Yin and Yin Qiao Wind—Heat pathogen in the exterior/early stage cold/flu
1.1 Sang Ju Yin (Mulberry Leaf and Chrysanthemum Drink)
When to use Sang Ju Yin (Wan): Sang Ju Yin (Wan) is the first of two Release Exterior formulas to be discussed. It is appropriate for addressing the early stages of the common cold or flu with the specific symptom of a dry cough. Other symptoms that this formula is useful for are: low-grade fever, dry/mild sore throat, watery or red eyes, and headache. This formula is most effective when used within 12-24 hours of symptoms developing and should be discontinued if the cough begins producing phlegm (i.e. develops into Wind-Heat in the Lungs). It should also be discontinued if the fever, sore throat, and body aches/fatigue worsen—this is a sign that the viral attack has moved into the Interior and needs to be addressed with other formulas.
Sang Ju Yin may also be appropriate for use in the early presentation of other conditions caused by invading heat toxins such as conjunctivitis, measles, chicken pox, and influenza.
Detailed Formula Breakdown:
This formula addresses the initial stage of a warm pathogen disease. The pathogen enters the body through the nose and mouth, first moving into the collateral channels of the Lungs where it obstructs and disrupts the normal flow and function of Lung Qi. Sang Ju Yin, then, works to:
- Release the warm pathogen from the collateral Lung Channels before it has a chance to sink into the interior of the Lung; and
- Disseminates (moves) the Lung Qi which has been obstructed by the pathogen.
Sang Ju Yin itself comprises eight herbs. The chief herbs are Sang ye (mulberry leaf) and Ju hua (chrysanthemum flower), which function to release the exterior (release the invading pathogenic influence (Wind-Heat) from the exterior layers of the body).
Two of the deputies in this formula, Lian qiao (forsythia) and Bo he (mint) are present to help the two chief herbs with their release exterior function. Lian qiao has anti-viral properties as well (something not known in classical times but nonetheless a beneficial aspect of this herb), and Bo he has the additional quality of bringing heat up from the interior to the exterior layers of the body before venting that heat out.
Sang Ye also has the specific function of helping to arrest cough, as do Xing ren (apricot pit) and Jie geng (platycodon). Sang ye specifically facilitates the flow of Lung Qi in the collateral channels of the lung (i.e. helps with early stages of a cough), and Xing ren and Jie geng work together to manipulate the Qi dynamic in the lung more generally; thus these three herbs work together to stop coughing before it can sink down into the lungs and create phlegm (i.e. turn to Lung Heat).
Lu gen (phragmites rhizome) assists in this formula by moistening the Lungs (helps with dry cough/overall balance in the Lung), and Gan cao (licorice root) clears additional heat and harmonizes the actions of the other seven herbs.
1.2 Yin Qiao (Honeysuckle and Forsythia (Tablets)
When to use Yin Qiao: Yin Qiao is indicated for the early stage of acute onset cold and flu marked most notably by low grade fever and sore throat. Other symptoms indicating the use of this formula are headache, aching shoulders and neck, and thirst. It is most effective when taken within 12-24 hours of the earliest symptoms of sore throat and/or achiness. For myself, I take 3 tablets every three hours until the either the sore throat and/or achiness goes away or the symptoms get worse. It should be noted that like Sang Ju Yin (above), the main treatment strategy of this formula is to release the exterior; therefore, once the viral pathogen works its way into the interior with more pronounced symptoms (e.g. higher fever, worsening sore throat, and/or the dry cough develops into a phlegmy, productive cough associated with some kind of chest/bronchial infection), its use should be discontinued and another formula to deal with Lung Heat w/toxins should be chosen.
Yin Qiao was also used classically as a pediatric formula and is appropriate for pediatric ear infection, tonsillitis, and a range of childhood viral diseases such as measles and chicken pox; however, please consult a trained TCM practitioner when administering this formula for children. The tablets in the bottle are formulated for adults—so while it is possible for a layperson to reduce the dosage for a child that weighs a fraction of what an adult does, it is not possible to modify the formula (like an herbalist can when mixing powders or raw herbs) to take into account the sensitivity with which a child’s system will process the herbs (nor to closely monitor their progress and make fine adjustments as treatment progresses).
Detailed Formula Breakdown: The main focus of this formula is to drive the viral pathogen out of the exterior layers of the body. The two chief herbs that do this are Jin yin hua (lonicera) and Lin qiao (forsythia). They are assisted in this task by Jing jie (Schizonepeta) and Bo he (mint), which also function to bring heat up and out of the interior—this means that by their very “inside ???? outside” nature they are fighting the Wind-Heat’s (virus and its symptoms) tendency to go deeper into the body.
It should also be noted that Jin yin hua and Lin qiao (which comprise roughly 35% of this formula) are ascending and dispersing herbs that also have anti-viral properties. This increases the effectiveness of this formula because it means that these two herbs are fighting the virus in the exterior layers of the body at the same time they are working to drive it out.
Dan dou chi (fermented soybean) is a cooling herb which reinforces the effect of driving Wind-Heat out of the body.
Dan zhu ye (lophatherum) is another cooling herb that clears heat in the Qi meridians. It is included in Yin Qiao in order to cool fever.
Niu bang zi (arctium/burdock fruit) has a cold nature and its function is to disperse Wind-Heat toxins (i.e. symptoms of the cold/flu). In this formula it is added to alleviate sore throat.
Gan cao (licorice root); Gan cao is here again as a harmonizing agent for the formula. It has heat clearing properties as well, so it fits with the overall “direction” of Yin Qiao.
Group 2: Gan Mao Ling and Zhong Gan Ling—Pathogen sinking into the interior/severe cold & flu
2.1 Gan Mao Ling
When to use Gan Mao Ling: Gan Mao Ling is a modern formula developed in Taiwan that has become quite popular for use in fighting respiratory viruses (colds and flu) since its introduction in 1988. While it is appropriate for use with early stage cold and flu (like Yin Qiao), its function is weighted a bit less toward the release exterior function and a little more toward the clear heat/resolve toxin function. This means that it contains a greater percentage of anti-viral herbs (roughly 75% of the formula) that are meant to attack the virus as it is starting to sink into the interior of the body. There is still some release exterior function happening with this formula, but the emphasis is shifting because the person is now presenting with such symptoms as: increasing fever (w/chills), worsening sore throat, fatigue, muscle aches, swollen glands, and stuffy/blocked sinuses and/or sinus headaches—in short, what we might call the “severe cold/flu stage”.
This formula is appropriate to take at the first sign of cold and flu symptoms (5 tablets every three hours); in fact, it is especially effective if taken in conjunction with Yin Qiao. If taken together, you get a very strong release exterior effect (from the Yin Qiao) combined with the strong anti-viral herbs in Gan Mao LIng—a potent one-two punch. Remember, though, that Yin Qiao is contraindicated if the cold and flu symptoms get worse—not so with Gan Mao Ling however, as Gan Mao LIng is meant to deal with Wind-Heat between the exterior and interior layers of the body (called Shaoyang syndrome in TCM language); therefore you can keep taking it as the cold and flu symptoms get worse (although as Wind-Heat sinks fully into the Lungs you will need most likely see diminishing returns and should consult your TCM trained health care practitioner in order to change treatment strategies).
One other note: this is an energetically “cold” formula and can thus be the source of stomach distention, pain, and/or loose stools, in which case its use should be discontinued.
Detailed Formula Breakdown:
The two chief herbs in this formula, Gang mei gen (ilex root) and San cha ku (evodia leaf), plus Ban lan gen (itasis root), all function to Clear Heat and Resolve Toxins—that is, they are strong anti-viral herbs (that make up roughly ¾ of this formula).
Jin yin hua (lonicera) and Ye ju hua (wild chrysanthemum) clear heat and release the exterior. Ye Jin Hua is exceptionally strong in this regard and is effective at addressing sore throat.
Huang jing zhi (polygonatum) is added to this formula to help sooth dry cough and also to help tonify the middle (i.e. help to digest and process such an energetically cold formula).
2.2 Zhong Gan Ling (severe cold & flu formula)
This is another modern formula that is appropriate for use after the initial stages of cold and flu have passed (after the first 24-48 hrs. of onset of symptoms) and the pathogens have begun to sink into the interior (the shaoyang stage of illness). Generally speaking, this formula addresses cold and flu when symptoms have become severe but not yet developed into a chest infection like bronchitis or pneumonia. Specifically, this formula addresses high fever and aching muscles in the shoulders and neck. Again, it should be noted that this is another energetically “cold” formula and prolonged use can cause upset stomach and/or loose stools, in which case the dosage should be lowered/monitored accordingly.
Detailed Formula Breakdown:
Zhong Gao Ling treats invasion by external pathogens that have reached the shaoyang stage. At this point it is no longer appropriate to try to release the pathogen through the exterior layer; rather, herbs that clear heat and resolve toxins must be directed to the blood level where they can attack the viruses that are causing the symptomology of “severe” cold and flu (fever of 101.5 and higher, severe sore throat and head and body aches).
Being a modern formulation, the chief-assistant-deputy model of formulation was not used. Instead, several herbs with strong anti-viral properties have been combined to resolve toxins and clear heat:
Mao dong qing (pubescent ilex root) and Ma bian cao (verbena) are anti-viral herbs that travel to the blood level to resolve toxins and clear heat
Shi gao (gypsum) and Ban lan gen (itasis root) reduce fever; Qing hao (artemisia) is another heat-clearing herb that enters the body at the blood level to assist Shi gao and Ban lan gen in getting deeper into the interior to combat fever (often referred in TCM as “blazing fire”).
Ge gen (pueraria) and Qiang huo (notoptergium) are potent wind dispelling herbs that release the muscle layer to ease painful tension and spasming in the neck and shoulders. Additionally, because these two herbs travel to an exterior locus of the body, they provide essential balance to a formula that contains five other herbs that go to the blood level to do their work. Ge gen and Qiang huo do this by providing an “up and out” pathway for the body to expel toxins.
Group 3: Other Anti-Viral Formulas
3.1 Chuan Xin Lian Wan (Andiographis Pill)
Chuan Xin Lian Wan is an anti-viral formula indicated for an acute heat toxin attack (w/inflammation) in the throat, liver, and/or lymph glands. I use it most commonly in the clinic for clients with cold and flu characterized by sore throat, but its applications are much wider: it can be effective in treating viral tonsillitis, viral hepatitis, measles, mumps, and herpes simplex and zoster. It can also be used as a general, system-wide heat-toxin removal formula or combined with other formulas to target specific areas (e.g. used with Long Dan Xie Gan Wan to address the herpes virus and other liver disorders or with Qian Lie Xian Wan for damp-heat/infections in the urinary tract).
Detailed Formula Breakdown:
Chuan Xin Lian Wan contains three anti-viral herbs:
Chuan xin lian (andiographis) is specific to the throat, appropriate for treating sore throat and swollen lymph glands, tonsillitis and other such conditions.
Ban lan gen (itasis root) works to reduce fever (clear heat) and resolve toxins throughout the body. It also has the property of removing congealed blood from the throat (called “throat bi (obstruction)” in TCM language).
Pu gong ying (Asian dandelion): this herb goes directly to the liver channel and thus is helpful in addressing viral conditions in the liver. Additionally, Pu gong ying helps detox the liver after it has cleaned the lymph.
3.2 Ban Len Gen Wan
Ban Lan Gen Wan is another TCM formula used for the used for the prevention and treatment of virus-related respiratory diseases such as influenza. It is especially effective at reducing high fever and reducing inflammation, whether this inflammation is specific to a certain area of the body or of a more generalized nature.
Detailed Formula Breakdown: Ban Lan Gen Wan, like Chuan Xin Lian Wan is composed of three anti-viral herbs, making it effective at addressing Toxic heat conditions in the body. The differences lie in the emphases of three herbs in this formula:
Ban len gen (itasis root) is known for going down into the interior levels of the body to clear heat—in other words, this presence of this herb in this formula is for the purpose of reducing high fever. It also works in tandem with Zi hua di ding (viola) to address conditions in which there is a build up of toxins/swelling in the throat (swollen glands, sore throat, tonsillitis etc…). Zi hua di dang clears heat toxins and reduces swelling and inflammation generally, and the Ban lan gen removes congealed blood through to the liver for cleansing (i.e. treats stagnation). So whereas Chuan Xin Lian Wan’s emphasis is on sending an anti-viral herb directly to the throat to outright kill viruses, Ban Lan Gen Wan’s emphasis is more to reduce system-wide fever/infection with a secondary emphasis on swelling and toxicity in the throat.
The third herb in the formula is Pu gong ying (Asian dandelion) which we first met above in formula 3.1 (Chuan Xin Lian Wan). In the new formula Ban Len Gen Wan, it again serves the function of clearing heat and removing toxins from liver, helping the body to heal completely from a viral attack.
3.3 Pu Ji Xiao Du Yin (Universal Benefit Drink to Eliminate Toxin)
This is a classical formula (developed over 800 years ago) to deal with virulent disease outbreaks and epidemics resulting from the influx of foreigners into China. It has both anti-viral and anti-bacterial herbs within it and thus is an excellent choice for acute onset cold and flu (Wind-heat invasion) marked by high fever, sore throat, and swollen glands (excellent for strep throat as well).
Detailed Formula Breakdown
The chief herbs in this formula are Huang qin (Chinese skullcap) and Huang lian (coptis root). These two herbs have both anti-viral and anti-bacterial qualities to them and are go-to herbs in the Chinese Medica for resolving Damp-Heat conditions. in the Plum Flower version of this formula, these two herbs are processed by being stir-fried in wine to help direct them to the head and neck, where the Wind-Heat pathogen is invading.
Lian qiao (forsythia) and Ban lan gen (itasis root) are also present in this formula in slightly smaller proportions for their anti-viral and heat clearing actions.
There are three herbs in this formula specific to aiding the throat: Niu bang zi (burdock fruit—which is also used in Yin Qiao (formula 1.2) for the same purpose, Ma Bo (lasiosphaera/puffball), which clears heat specifically in the lungs and throat, and Xuan shen (scrophularia/figwort root), which is the main herb in this formula that directly addresses toxic swelling in the lymph glands (caused by all the other anti-microbial herbs doing their job).
Other herbs in this formula works in varying ways to help expel Wind from the body (i.e. arrest a pathogenic influence that is sinking into the interior of the body and push it up and out): Chai Hu (bupleurum), Sheng ma (cimicifuga rhizome), and Huang qin (Chinese skullcap) combine to take Wind-Heat that is trapped between interior and exterior layers (shaoyang stage) and releases it through the muscle layer. Jie geng (platycodon) assists in the function through its quality of dispelling phlegm from the lungs and throat (i.e. an “up and out” directionality to its nature). Lian qiao (forsythia) is also an herb with exterior-releasing properties.
3.4 Wu Wei Xiao Du Wan (Five Flavor Teapill)
This formula was originally created in the 1700’s to treat boils, carbuncles, and other hard sores as well as infected wounds accompanied by infection and high fever (when a blood poisoning was a deadly serious threat). In the modern clinic, it is indicated for a variety of conditions in which there is an inflammatory response marked by heat, redness, pain, and swelling (e.g. infected wounds, scrofula, and other skin infections) as well as a variety of other conditions (e.g. blood infections, urinary tract/kidney infections, impetigo, and mastitis). This can also be a helpful formula for dealing with conditions not responding well to antibiotics.
Detailed formula Breakdown
This formula addresses fire toxins that accumulate in the body and create hard sores that are red and painful. The chief herb in this formula is Jin yin hua (lonicera), which functions here to pull heat out of the qi and blood levels and dissipate the swellings caused by that heat. The remaining four herbs in this formula are also cooling, anti-viral herbs and which reduce swellings and disperse clumps: Zi hua di dang (viola), Tian kui zi (semiaquilegia– this herb is specific for use with hardened, infected sores), Pu gong ying (Asian dandelion), and Ye ju hua (wild chrysanthemum flower)
