#Herbal #Andrographis Inhibits the Onset of Skin Cancer By Cell-Cycle Arrest, Researchers Discover

By Kyle J. Norton

Andrographis, the forgotten herbal medicine may consist of potency in reduced risk and treatment of skin cancer with fewer or no side effects, the renowned institute study suggested.

Andrographis paniculata also known as Andrographis is a herbaceous plant, genus Andrographis, belonging to the family Acanthaceae, native to India and Sri Lanka. It has been used in traditional Siddha and Ayurvedic in treating the common cold, flu, upper respiratory infections, infectious diseases, diarrhea, dysentery, cholera, pneumonia,.....

Skin cancer is a medical condition of uncontrolled growth of abnormal skin cells and is often detected at an early stage.

According to the joint study led by Sri Krishnadevaraya University, the leaf extract of Andrographis nallamalayana (AN) significantly reduced the viability and survival of cells in skin cancer cell lines on A375 and B16F10 as shown in MTT assay and clonogenic assays.


The anti-skin cancer effects of the leaf extract were also associated with ameliorating the expression of Bcl-2, an anti-apoptotic protein that induced the expression of a pro-apoptotic mechanism.

Dr. Purushotham G, the lead author said, "The extracts of AN exhibited significant anti-proliferative, anti-inflammatory and pro-apoptotic activities on melanoma skin cancer cell lines"


In immunofluorescence analysis, leaf extract Andrographis nallamalayana (AN), significantly attenuates the expression of NF-κB target genes with function in regulated cytotoxicity expression in the tumor cell.

Furthermore, the extract also exhibited direct anticancer activity on cancer cells by cell-cycle arrest at the G0/G1 phase through induction of cell-cycle inhibitory protein p27 involved cell proliferation and decreased expression of cyclin-dependent kinase 4 (CDK4) in cell controlling, probably through enhancing immunomodulatory property.

Taking together, there is no doubt that Andrographis processes a pharmaceutical value in reducing the risk and controlling skin cancer, but the intake of large quantities can only be prescribed by an herbalist.
