There has been some progress in the prevention and treatment of IVP by using TCMs. However, most research has focused on viral replication, the role of inflammatory cytokines, oxidative stress, and lung inflammatory cell infiltration in the pathogenesis of the disease, while there has been relatively little in-depth research on the lung lesions caused by influenza virus infection and on the role TCMs may have in preventing them. At present, analyses of the chemical components and mechanisms of action of TCMs useful in the treatment of IVP are insufficient, and this restricts their further use.

Experimental Study Bee Pollen Honey
The research investigated the antiviral properties of bee-collected pollen (BCP) and bee bread (BB), including versions that had undergone artificial fermentation. The experiment also assessed separate proteins, water content, and -butanol portions of these substances. The analysis evaluated their effectiveness against the H1N1 strain of the influenza A virus (IAV). The antiviral behavior of these materials was taken in lab conditions via a comparative real-time PCR analysis working on their inhibitory concentration and selectivity index.
The outcomes revealed artificial fermentation improved the antiviral effectiveness of BCP. The protein fractions within the BCP and BB presented the greatest antiviral activity. Observations also highlighted that the chemical composition, prominent in proteins, and potentially microbiome metabolism determined the antiviral properties of BCP and BB. The chemical profile analysis emphasized the existence of some specialized metabolites that might be contributing towards this antiviral action.

Systematic Review Antiviral Green Tea
To identify the potential benefits of green tea in influenza prevention, a methodical review and combined analysis of eight distinct research studies involving 5,048 participants was completed. The effect of green tea catechin treatment was tested against control conditions and assessed based on infection rates. Five of these studies were randomized controlled trials involving 884 participants and three were cohort studies with 2,223 participants. Subgroups such as those who gargled or took orally ingested forms of green tea were also analyzed separately. Further to this, the possibility of publication biases was evaluated using Begg's and Egger's tests.
The results showed both the randomized trials and the cohort studies displayed significant preventative effects on influenza infection for those treated with green tea catechins. Notably, there was no evidence of non-uniformity within the data, reinforcing these findings. The pooled results of different consumption methods further supported these findings, showing no disparities among the subgroups. These results suggest the consumption of green tea has tangible prophylactic effects against influenza infection.

Review Article
Influenza infection is a highly contagious, acute febrile respiratory disease caused by the influenza virus. Traditional Chinese Medicine (TCM) has dominated plenty of theoretical and practical approaches in the treatment of influenza. It is, therefore, important to highlight the effects of TCM in the clinical treatment of influenza and their impact on inhibiting the growth of this virus in laboratory experiments. We scrutinized existing evidence on whether TCM is effective in clinical applications. Moreover, we described the potential mechanisms of TCM against the influenza virus. Our findings provide analytical evidence that supports the effectiveness of TCM in treating influenza infections as well as their mechanisms against this virus.

The overall characteristics of TCM in treating viral infectious diseases are that it can significantly lighten the symptoms and bring down the fever quickly; however, the time of viral nucleic acid to be negative in TCM is slower as compared to the chemical antiviral drugs.
Some randomized controlled trials showed that Maxingshigan decoction (a classical TCM recipe that is commonly used for pneumonia composed of Chinese ephedra, apricot kernel, gypsum, licorice), Yinqiaosan decoction (a famous TCM recipe mainly composed by Lonicera japonica and Fructus forsythiae is commonly used for cough and sore throat caused by virus infection), and modern Chinese patent medicine Lianhua qingwen capsules (a TCM capsule, which is approved by the China Food and Drug Administration for the treatment of flu) relieve the clinical symptoms of influenza patients and shorten the time of disease progression.

Review Article Common Cold, Flu & Viral Infections MRSA
Present, several studies on the anti-virus activity of single Chinese medicinal herb, such as Fructus forsythiae, Radix isatidis, and Scutellaria baicalensis, using modern technology confirmed the effective constituent and materials, as well as the functional mechanism of the relevant parts. A systematic analysis found that TCM decoction and Ganmao capsule (a non-prescription Chinese patent medicine composed of some herbs for clearing heat and toxicity is commonly used in treating cold and flu) had better effects on the treatment of H3N2 and influenza B, respectively, than amantadine and ribavirin.
In terms of anti-inflammation, TCM can alleviate the damage caused by excess inflammatory reactions initiated by a virus. The single and compound Chinese medicinal herbs which can cause clearing heat and toxicity could decrease the cytokine storm resulting from the production of several species of pro-inflammatory cytokines and anti-inflammatory cytokines aim to improve the injury of tissue and organs. In turn, this phenomenon promotes blood circulation and removes stasis, thereby confining the inflammation and promoting its absorption. In the case of SARS, a rapidly spreading infectious disease, TCM combined with corticosteroids during the early stage of the outbreak could decrease the mortality by promoting innate immunity to relieve inflammation.
Subsequently, the TCM compounds of Chinese herbs analyzed based on the theory of strengthening healthy Qi and clearing pathogenic factors with the feature of multicomponent, multi-channel, and multiple targets exerted a synergistic effect on inhibiting the virus directly, relieving the immunopathological injury, and controlling the inflammatory reaction caused by virus infection.

A Review Article published in 2019 in the journal APMIS found that Clinical efficacy can be improved by the combination of Chinese and Western medicine in the treatment of bacterial infectious diseases. The combination of traditional Chinese medicine (TCM) intravenous preparations with conventional antibiotics can effectively improve the clinical efficacy of community-acquired pneumonia (CAP) and promote the early rehabilitation of patients, thereby reducing the rate of mortality of the patients. Previous studies showed that Xiyanping injection (TCM injections are approved by the China Food and Drug Administration for the treatment of respiratory infection; the main ingredient is andrographolide sulfonate) combined with piperacillin and sulbactam significantly improved the clinical efficacy of pulmonary infection in the elderly. Pulmonary infection is the most common complication and cause of death in stroke patients. Compared to simple symptomatic support treatment, the recovery rate and efficiency of Qingjin huatan decoction (famous TCM recipe composed of Scutellaria baicalensis, Fructus gardeniae, Fritillaria thun-bergli, for clearing heat and reducing phlegm) combined with Xiaochengqi decoction (purgative prescription) in the treatment of apoplexy-related lung infection is greatly improved. The symptoms of patients with pulmonary infection complicated with sepsis were significantly improved after treatment with the addition of Shengjiang powder combined with basic Western medical treatment including antibiotics and expectorant application. Consequently, the APACHE2 score was significantly reduced, and the levels of inflammatory cytokines, such as CRP, TNF-α, and IL-6 were also significantly reduced.
A Review Article published in 2019 in the journal APMIS found that Traditional Chinese medicine can restrain some infections induced by various drug-resistant bacteria. A large number of studies have shown that multiple traditional Chinese medicine (TCM) compounds, single herbs, and monomers have effects on inhibiting drug-resistant bacteria in both in vitro and in vivo studies such as MRSA, Acinetobacter baumannii, and Pseudomonas aeruginosa. The mechanism of treating drug-resistant bacteria in TCM mainly includes the following two aspects: eliminating plasmid and inhibition of the active efflux pump system. Forsythia decoction can inhibit the active efflux pump of A. baumannii, resulting in the variation of an adeB sequence of efflux pump coding gene. In addition, TCM has a large impact on the production of the inactivating enzyme of antimicrobials to reverse the drug resistance. To inhibit the growth and reproduction of bacteria, Chinese medicinal herbs can alter the structure of bacterial cell wall to affect permeability. Some herbs such as rhubarb and berberine can restrain the formation of biofilms to inhibit the MRSA. Notably, the antibacterial activity of TCM with little side effects is equivalent to that of antibiotics. A study showed that Chinese medicine, Mayushihuang decoction, has the same efficiency with teicoplanin for clearing MRSA; however, distinct adverse effects were not detected in the TCM group as compared to abnormal hepatorenal function in the teicoplanin group.
A Review Article published in 2018 in the journal Molecules found that Tea catechins, found in green tea, may reduce the rates of influenza infection and diminish certain cold symptoms. The research methodology started with interpreting several experimental studies which reported that tea catechins can inhibit influenza viral adsorption and suppress replication and neuraminidase activity. These catechins were also found effective against some common cold viruses and helped to enhance immunity against such viral infections. Additionally, epidemiological studies conducted since the late 1990s were examined which suggested that regular consumption of green tea may decrease influenza infection rates and some cold symptoms, and gargling with tea catechin could potentially protect against the development of influenza infection. For the discussion of results, the studies collectively showed that tea catechins have potential antiviral activity against influenza and some cold viruses. Although clinical evidence supporting these effects remained unconclusive, the review showed promising trends. The consumption of green tea and gargling with tea catechins could lead to potentially decreased rates of influenza infection and lessened cold symptoms according to the analyzed epidemiological studies.
A Systematic Review published in 2018 in the journal BMC Complementary Medicine and Therapies found that Ma Huang Tang may lower the duration of fever when it is used alone or in combination with neuraminidase inhibitors and may be a well-tolerated treatment. Twelve relevant studies were identified, including two randomised controlled trials (RCTs, N = 60) and ten non-randomised studies (NRSs, N = 1110). We found that maoto plus NAIs was superior to NAIs alone in terms of the duration of fever in one RCT and four NRSs. The duration of symptoms or virus isolation did not differ between maoto and NAIs. No severe side effects or adverse reactions were reported related to maoto or NAIs. Although we could not reach a definitive conclusion because of the small sample sizes and high risk of bias in the analysed studies, maoto may lower the duration of fever when it is used alone or in combination with NAIs and may be a well-tolerated treatment. More RCTs are needed to determine the efficacy and safety of maoto.
A Meta-Analysis published in 2016 in the journal Journal of the Chinese Medical Association found that Compared with oseltamivir, Chinese herbs might have superior potential effects on fever resolution and similar effects on viral shedding. In this review, several Chinese herbal medicines demonstrated a potentially positive effect on the influenza A (H1N1) strain, especially on its time to defervescence, as in the studies analyzed, the mean time to defervescence in the TCM treatment group was less than that noted in the control group. Furthermore, the duration of influenza A (H1N1) shedding in the integrated Chinese and Western medicine subgroup was less than that noted in the control group, although existing evidence indicated that the difference in duration of viral shedding and effective rate between the two groups was statistically similar. The applicability of the included studies was limited, however, because their inclusion criteria, interventions, durations, and outcome measures were different. Consequently, more well-designed trials are required.
A Network Pharmacology published in 2014 in the journal Archives of Medical Research found that Manuka honey exhibits significant anti-influenza viral activity, inhibiting replication with virucidal effects. Combining manuka honey with existing drugs enhances their efficacy, suggesting its medicinal potential. This study aimed to address the urgent need for novel anti-influenza drugs by evaluating the anti-viral activity of honey, focusing on manuka honey. Antiviral activities were assessed using MDCK cells, revealing that manuka honey efficiently inhibited influenza virus replication with an IC50 of 3.6 ± 1.2 mg/mL and a CC50 of 82.3 ± 2.2 mg/mL, resulting in a selective index of 22.9. Virucidal effects were identified as the underlying mechanism. Furthermore, combining manuka honey with zanamivir or oseltamivir significantly enhanced their efficacy, showcasing the potential medicinal value of honey, particularly manuka honey, against the influenza virus. The study underscores the potent inhibitory activity of honey, especially manuka honey, against influenza viruses, offering promising medicinal implications. The observed virucidal effects and the synergistic enhancement of known anti-influenza drugs highlight the multifaceted potential of honey in combating influenza infections. Further exploration of the specific mechanisms underlying these effects could contribute to the development of effective anti-influenza therapies.
A Network Pharmacology published in 2014 in the journal Archives of Medical Research found that Honey, in general, and particularly manuka honey, has potent inhibitory activity against the influenza virus, demonstrating a potential medicinal value. Antiviral activities of honey samples were evaluated using MDCK cells. To elucidate the possible mechanism of action of honey, plaque inhibition assays were used. Synergistic effects of honey with known anti-influenza virus drugs such as zanamivir or oseltamivir were tested. Manuka honey efficiently inhibited influenza virus replication (IC50 = 3.6 ± 1.2 mg/mL; CC50 = 82.3 ± 2.2 mg/mL; selective index = 22.9), which is related to its virucidal effects. In the presence of 3.13 mg/mL manuka honey, the IC50 of zanamivir or oseltamivir was reduced to nearly 1/1000th of their single use.
A Systematic Review published in 2013 in the journal Cochrane Database of Systematic Reviews found that Most Chinese medical herbs in the included studies showed similar effects to antiviral drugs in preventing or treating influenza. This updated review assessed the therapeutic effects and safety of Chinese medicinal herbs as an alternative and adjunctive therapy to other commonly used drugs for influenza. Eighteen studies involving 2521 participants were included in the review. 'Ganmao' capsules were found to be more effective than amantadine in decreasing influenza symptoms and aiding recovery in one study (in which adverse reactions were mentioned in the amantadine group although no data were reported). There were no significant differences between 'E Shu You' and ribavirin in treating influenza, nor in the occurrence of adverse reactions. The remaining 17 Chinese herbal trials showed a similar effect to antiviral drugs in preventing or treating influenza. However, since these included studies were of poor quality, the evidence does not support or reject the use of any Chinese herbal preparations for influenza. High‐quality trials are required.
