As COVID-19 rips through China's vast population, making millions sick and fuelling a shortage of drugs, many are turning to old-school traditional medicines to battle the aches and pains of the virus.
President Xi Jinping has promoted traditional Chinese medicine (TCM) since the start of the pandemic, while health officials have hailed its "important role" in fighting the coronavirus.
Encompassing a range of treatments from herbal remedies and massages to acupuncture and diets, TCM has been used for thousands of years to treat all manner of ailments.
Critics say it is pseudoscientific and ineffective in treating actual illness, and there is little peer-reviewed data to back claims of its efficacy.
But millions in China use it, often in conjunction with modern medicine to alleviate symptoms.
Beijing consultant Yu Lei, 38, had a fever after catching COVID, so he made a herbal tea with reputed anti-inflammatory properties featuring cassia twig — a kind of Chinese cinnamon — peony roots, liquorice, jujubes and ginger.
"In our family, we often use Chinese medicines," he told AFP, adding that his fever subsided after drinking the brew.
According to followers like Yu, TCMs have fewer side effects and work slower to regulate the body, rather than Western medicines that "fight the symptoms but rarely the source of the illness".
Beijing has urged local authorities to "actively and objectively publicise the role and efficacy of TCM brews in the treatment of COVID-19".
However, Ben Cowling, chair of epidemiology at the University of Hong Kong's School of Public Health, told AFP: "We don't know whether these treatments are effective or not, because they haven't been studied in clinical trials."
"I wouldn't rule out the possibility that some of them are effective, but I also wouldn't rule out the possibility that some of them might even be harmful."
The World Health Organisation only recommends COVID treatments that are based on chemical drugs. When contacted by AFP about TCM, the body said it advised countries to "gather reliable evidence and data on traditional medicine practices and products".
'Same logic'
Western medicine remains the preferred mode of care in China, but proponents of TCM say combining the two is effective in treating COVID-19.
Liu Qingquan, director of the Beijing Traditional Chinese Medicine Hospital, says they "complement each other and can solve fever, sore joints, fatigue, sore throat, cough and other symptoms".
Experts have taken to television to praise TCM since the start of the pandemic, with one product in particular — Lianhua Qingwen — benefiting from intense promotion by authorities.
Many users are convinced of its usefulness, with some studies suggesting it can help alleviate symptoms. Capsules of the medicine were given to all Hong Kong residents when a COVID wave hit the city last year.
But some online critics in China charge that Lianhua Qingwen is no more effective than peaches in syrup — a staple comfort food for sore throats in China — and social media users have complained of being handed the TCM instead of ibuprofen or paracetamol.
Lan Jirui, a doctor of Chinese medicine in Beijing, told AFP: "It's the same logic as Western medicine.
"If the drug is bought on the prescription of the doctor, it will probably be effective. If it is bought randomly from the pharmacy, then maybe not."
