Traditional Chinese medicine for COVID-19 treatment
The current 2019-nCoV outbreak is moving rapidly , the cumu-
lative number of confirmed cases in mainland China has reached
80151, with 47,204 (58.89 %) cured cases and 2943 (3.67 %) deaths as
of 2-Mar-2020, and no specific drug has been discovered for Cor-
onavirus Disease 2019 (COVID-19).
- However, a number of clinical
practice results showed that traditional Chinese medicine (TCM) plays
significant role in the treatment of COVID-19, bringing new hope for
the prevention and control of COVID-19.
TCM has a long history and played an indispensable role in the
prevention and treatment of several epidemic diseases.
- During the SARS
epidemic in 2003, the intervention of TCM has also achieved remark-
able therapeutic effect.
- During the treatment period of COVID-19, more
than 3100 medical staff of TCM were dispatched to Hubei province, and
TCM scheme was included in the guideline on diagnosis and treatment
of COVID-19 , and TCM experts fully participate in the whole rescue
- The decoction, Chinese patent medicine, acupuncture and
other characteristic therapy of TCM was comprehensively employed,
mainly treated based on syndrome differentiation.
- Specific TCM wards
were set up, and established the designated hospital, moreover, TCM
team participates in treatment collectively.
- Currently, the total number
of confirmed cases treated by TCM has reached 60,107 . In 102 cases
of mild symptoms treated with TCM, the clinical symptom dis-
appearance time was shortened by 2 days, the recovery time of body
temperature was shortened by 1.7 days, the average length of stay in
hospital was shortened by 2.2 days, the improvement rate of CT image
was increased by 22 %, the clinical cure rate was increased by 33 %,
27.4 % reduction in the rate of common to severe cases and 70 % in-
crease in lymphocyte.3
- In addition, in the treatment of severe patients
with TCM, the average length of stay in hospital and the time of nucleic
acid turning negative has been shortened by more than 2 days.
- From current treatment results, TCM based on an over-all symptoms
of 2019-nCoV pneumonia patients, has suggested to prescribe pre-
scription that are likely to be effective, such as qingfei paidu decoction
(QPD), gancaoganjiang decoction, sheganmahuang decoction, qingfei
touxie fuzheng recipe, etc.
- QPD which consisted of Ephedrae Herba,
Glycyrrhizae Radix et Rhizoma Praeprata cum Melle, Armeniacae Semen
Amarum, Gypsum Fibrosum, Cinnamomi Ramulus, Alismatis Rhizoma,
Polyporus, Atractylodis Macrocephalae Rhizoma, Poria, Bupleuri Radix,
Scutellariae Radix, Pinelliae Rhizoma Praepratum cum Zingibere et
Alumine, Zingiberis Rhizoma Recens, Asteris Radix et Rhizoma, Farfarae
Flos, Belamcandae Rhizoma, Asari Radix et Rhizoma, Dioscoreae Rhizoma,
Aurantii Fructus Immaturus, Citri Reticulatae Pericarpium, and
Pogostemonis Herba, has been promoted as a general prescription in the
diagnosis and treatment plan of COVID-19 in China .
- Among the 701
confirmed cases treated by QPD, 130 cases were cured and discharge
clinical symptoms of 51 cases disappeared, 268 cases of symptoms
improved, and 212 cases of stable symptoms without aggravation .
The effective cure rate of QPD against COVID-19 is over 90 %. Ac-
cording to the theory of TCM, the target organ location of COVID-19 is
the lung, and the etiology attribute is “damp and toxin plague”.
The network pharmacology analysis showed that QPD has an overall reg-
ulatory effect via multi-component and multi-target.
The primary site of pharmacological action is the lung, as 16 herbs to lung meridian, which indicated that the decoction is mainly specific for lung diseases.
In addition, it can play the role of dehumidification through the rise and
fall of the spleen and stomach, and exhibited the protection for heart,
kidney and other organs.
Among the potential targets screen, most of
them co-expressed with ACE-2, the receptor of COVID-19, indicating the potential improvement of COVID-19. It can inhibit the replication of COVID-19 by acting on multiple ribosomal proteins. COVID-19 can lead to strong immune response and inflammatory storm .
Functional enrichment analysis showed that QPD could inhibit and alleviate ex-
cessive immune response and eliminate inflammation by regulating
immune related pathway and cytokine action related pathway .
Furthermore, through the prediction of molecular docking, it was found
that patchouli alcohol, ergosterol and shionone in the formula had
better anti−COVID-19 effect, which provided new molecule structures
for new drug development .
Here, we take one highly suspected COVID-19 patient treated with
TCM as a case example to show its effectiveness .
The male patient
was on a business trip in Wuhan for several days before the onset of the
disease. During the admission period, fever and cough were repeated,
and respiratory rales of both lungs were not obvious.
Western medicine was used firstly, including orally take oseltamivir phosphate capsule,
intravenous infusion of ganciclovir, aerosol inhalation of recombinant
human interferon a1b, etc. Although the nucleic acid test was negative,
the results of chest CT showed that the fusion of two lung ground glass
shadows was enlarged and the density was increased, which was more
advanced than that of admission (Fig. 1a-1c).
As the serious illness, combined with the patient’s performance of damp-heat syndrome, and
the heat is more serious than damp, QPD was added for treatment.
On the night of administration, the body temperature dropped to 36.2 ℃,
and then tended to be normal.
After 6 days of treatment, chest CT was
better than before, tracheobronchial shadow was normal, and in-
flammation was obviously absorbed (Fig. 1d).
The patient had no fever or asthenia, coughing occasionally, and the rales of two lungs were weaker than before.
After discharge, continue to take 7 doses of the prescription, occasionally cough, no special discomfort was found.
The clinical symptoms and imaging examination of the patients improved
significantly after the treatment, reflecting the advantages of TCM.
TCM has own characteristics such as holistic concept, balance of Yin
and Yang, syndrome differentiation and treatment, strengthening the body resistance to eliminate pathogenic factors.
TCM has thousands of years of experience in regulating the body and enhancing the resistance to epidemic diseases, with unique insights and prevention and control
For mild and common patients, the early intervention of TCM can effectively prevent the disease from transforming into severe
and critical disease.
In the severe cases, TCM has won time for rescuing them by improving symptoms (http://www.scio.gov.cn/xwfbh/
Furthermore, the reason why TCM
works is not only to inhibit the virus, but might block the infection,
regulate the immune response, cut off the inflammatory storm, and
promote the repair of the body. Moreover, the prevention and control
measures of COVID-19 fully reflect the ideology of “preventive treat-
ment of disease”. Apart from the epidemic diseases recorded in the Han
Dynasty should be isolated, the preventive measures of TCM also in-
clude psychology, sports, diet, medication, etc.
In the next prevention and control work of COVID-19, it should give full play to the advantages of TCM in syndrome differentiation and the whole therapeutic effect, reduce the complications as well as death rate.
Besides, the scientific research should also be carried out on the TCM
with definite curative effective of COVID-19, to comprehensively
evaluating its action mechanism and in-depth understanding COVID-

Treatment practice of
COVID-19 showed that early intervention of TCM is important way to improve cure rate, shorten the course of disease, delay disease progression and reduce mortality rate.
