Clinical Trial shows how Lianhua Qingwen has the potential to prevent COVID-19 after exposure


The Omicron variant of COVID-19 has again increased the number of cases of the ongoing pandemic not only in the country but overseas as well.

Although there is another surge of COVID-19 infection, it is said that Omicron has milder symptoms. Some are optimistic that this variant will act as a natural immunity and lead to the end of the pandemic. However, even if the symptoms caused by the Omicron are mild, recent research by NIH (National Institute of Health) in China showed that the virus might stay in human body, brain and other organs for over 200 days even after turning in a negative result.

For this reason early treatment has always been key in going through this COVID-19 surges. Keeping over-the-counter cough and cold medicine at home is good practice, especially during this time. Another option is to keep stock of Lianhua Qingwen capsules on hand for the treatment of Omicron related symptoms.

Throughout the pandemic, Lianhua Qingwen has been a know treatment for lung ailments typically brought about by COVID-19. Various clinical trials have showed that Lianhua Qingwen capsules can relieve the symptoms associated with COVID-19 and speed up recovery. However, with this fast spreading Omicron variant, chances of exposure are too high and prevention should also be considered.

In a recent study entitled “Efficacy and Safety of Lianhuaqingwen Capsules for the Prevention of Coronavirus Disease 2019: A Prospective Open-Label Controlled Trial” published in, it was concluded that Lianhua Qingwen capsules conferred preventive effects on those exposed to COVID-19. And “in light of their efficacy and safety profile, LH capsules can be considered useful for the prevention of COVID-19 upon exposure.”

In the same study, incidence rate of symptoms after close contact for those taking Lianhua Qingwen were 1.2% while that for other prophylactic drugs was 6.8%. Incidence rate for those who did not use drugs was 8.8%.

Despite its safety, Lianhua Qingwen is currently classified as a prescription drug (Rx)—requiring a doctor’s prescription. Prescription-holding consumers may purchase it in all Mercury Drug Stores, Southstar Drug, Watsons, Rose Pharmacy, and TGP nationwide and other pharmacies at a suggested retail price of P288.00/box (24 capsules/box).
