Herbal Extract of Traditional Medicine Works to Ease Lung Inflammation and Fibrosis, Early Study Reports

A herbal extract derived from a product used in Korean traditional medicine may be a potential alternative treatment for idiopathic pulmonary fibrosis (IPF), a mouse study suggests.

The herbal extract was found to reduce inflammation and markers of lung fibrosis in a mouse model of PF and in lung fibroblasts collected from patients.

The study, “A standardized herbal extract PM014 ameliorates pulmonary fibrosis by suppressing the TGF-β1 pathway,” was published in the journal Scientific Reports.

Esbriet (pirfenidone, marketed by Genentech) and Ofev (nintedanib, marketed by Boehringer Ingelheim) are two FDA-approved therapies for IPF that can delay lung function decline.

“Unfortunately, these drugs have some serious potential side effects and neither of these drugs have been found to effectively reverse lung fibrosis,” the researchers wrote, emphasizing the need to develop new IPF therapies.

PM014 is a novel herb extract made from seven plant species and derived from Chung-Sang-Bo-Ha-Tang (CSBHT), an herbal product used for treating lung disorders in traditional Korean medicine.

Prior studies reported that the extract is able to ease inflammation in mouse models of chronic lung diseases, including chronic obstructive pulmonary disease (COPD) and asthma.

A team led by researchers at the College of Korean Medicine, Kyung Hee University, in South Korea, investigated if PM014 could be of benefit to IPF. The team tested if the herbal extract could ease disease signs in a mouse model of bleomycin-induced PF, a widely used experimental model of the disease.

Results showed that oral, daily administration of PM014 after lung fibrosis onset suppressed inflammation and eased lung scarring (fibrosis) in a dose-dependent manner in the animals.

The treatment reduced the amount of inflammatory cells reaching the lungs, and lowered production of pro-inflammatory mediators, including transforming growth factor (TGF)-β1, “one of the most potent inducers of fibrosis,” the researchers wrote.

Importantly, the team also looked at the changes PM104 induced on lab cultures of lung epithelial cells and fibroblast cells taken from healthy donors and IPF patients.

Results showed that PM014 prevented cells from undergoing alterations crucial to the development of fibrotic lesions in the lungs, namely epithelial-mesenchymal transition (EMT). During this process, epithelial cells transform into migratory or invasive mesenchymal cells; these cell, in turn, release proteins like collagen, which lead to the hardening and scarring of tissues.

Of note, PM014 inhibited the activation of lung fibroblasts from IPF donors, blocking their ability to migrate and produce collagen.

Data from this work suggest that “PM014 administration exerts a protective effect against lung fibrosis and highlight PM014 as a viable treatment option that may bring benefits to patients with IPF,” the team concluded.

      Dear readers,

      Thank you for reading and commenting on pulmonaryfibrosisnews. The herbal extract PM014 was only tested in mouse models of pulmonary fibrosis in this early, preclinical study. The specific herbal extract used was prepared by researchers in the laboratory to be used in their study. Therefore, to our knowledge, it is not commercially available.

      Kind regards,

      Ana Pena

      Go to a Chinese or Korean Herbalist and see if they can figure it out. The names were all listed. There is also the name of the University in Korea. That’s what I’m going to do.

  1. Yes, I have been searching for a Koreon supplement that can stop the production of collegan. Eastern natural medications are worth a try. I am on Eapiret, Which will hopefully slow down the disease, but so many of us are desperate for another life saver ASAP. We don’t know how long we have before our illness squeezes the life out of us.

    Hello .
    I m sure that you understand that now a lot of patients are
    Interested to know how to bet this and where and if its avalable.
    If not… its not fair according to me to give falso hope to us patients
    Suffering from IPF.
    Please let us all know the next steps please….

    It is to be expected that reports such as these will raise hope in those of us suffering from this terrible disease. Regrettably, the reality is such that while there is great interest in medical advances many of those we read of will not be available for some time and therefore may only help those who will be diagnosed in the future.
    There may be some small comfort in knowing that this disease will not long continue to devastate future lives.

      Dear Steven,

      Thank you for your comment. From the published study, it seems that researchers looked only to the collagen present at lung tissues, not to the collagen present in other organs or tissue types. This happened both in mice experiments and in experiments using human cells (lung fibroblasts taken from IPF patients). I hope this helped.

      Kind regards,

    I’m frustrated by continually coming across ‘promising results’ only to find these results are applicable to mice! These false flags are not helpful. Well, not to me. At least they let us know that chemical companies and doctors are investigating and looking for a way to stop the fibrosis or slow it even more than the current medications.

    My wife is taking “Metformin”, drug for diabetes. She is taking 500 mg ie try to slow down lung fibrosis. Hoping that the expert will come up with new drug not too expensive to save life. Better for the expert to provide us some drugs to use and finalise latter.
