Banlangen granules, by Yu Lam Brand. Dissolves instantly in hot water to make a slightly sweet, herbal tea.

Banlangen is the dry root of the plant Isatis indigotica, with a clinical medical history spanning thousands of years in China.

A household staple in Chinese households, Banlangen is the most recommended anti-viral herb for colds in Traditional Chinese Medicine, and is popularly used both to prevent and reduce the severity of the common cold, as well as other viral infections. It is one of the most studied herbs in Chinese medicine, with numerous clinical studies demonstrating its ability to inhibit virus absorption to the host cells—it plays a role in directly killing pathogenic viruses and regulates the immune system to enhance anti-virus ability.

First documented as an herbal medicine in The Divine Husbandman's Herbal Foundation Canon, a well-known medical text from the Han Dynasty (circa 200 AD), it’s since been highlighted as a classic anti-viral and anti-influenza herb in China’s official Pharmacopoeia. It anti-viral and anti-inflammatory properties have been confirmed both in vivo and in vitro.

Most often sold in packets of granules that dissolve in water to make a tea, Banlangen has experienced a huge surge in popularity during the pandemic, with sales in China rising 3,130% in one day after a research team found that Banlangen granules were effective against the SARS-CoV-2 virus in a series of in vitro studies.

In one remarkable study, researchers found that natural compounds and extracts from Banlangen have better therapeutic action against influenza virus (FM1) than the synthetic antiviral drug Ribavirin.

Moreover, compared with Ribavirin, natural Banlangen compounds or extracts have significantly higher prophylactic (preventative) activity against influenza virus (FM1).

Banlangen extracts were observed to exert their anti-influenza activity by inhibiting virus multiplication and blocking virus attachment. In vivo experiments from another study also revealed a Banlangen extract to significantly inhibit pneumonia and virus proliferation in lung tissue.
