Fu Ling Gan Cao Dui Yao pair as SARS prevention and ease of symptoms

Looking into the origins of hydroxyquinolone, I was struck by the mysterious origins of its progenitor Nalidixic Acid. Could it be that the synthesis of the quinolone family of antibiotics was actually borrowed from Chinese Medicine?

So looking at the herbal formula that we can use to treat the symptoms of phlegm and cool-dryness for SARS-CoV-2 (COVID-19’s virus), I went in search of the ingredient list of Xing Su San. From the Bensky text,
“Zi Su Ye, Qian Hu, Xing Ren, Jie Geng, Zhi Ke, Chen Pi, Fu Ling, Zhi ban xia, Sheng Jiang, Da Zao, and Gan Cao.”

Then turning to the single herb Bensky text, which lists the active chemicals, I searched for signs of HDCQ, NA, or even Napthyridone.  What I found was that not the most active part of the formula (the first listed herbs), but the tonifyier Fu Ling – a common fungus called Indianbread in the United States – and the envoy Licorice (Gan Cao), contained these chemical constituents which enable them to be “slippery” and “moisten dryness”:

Fu Ling
Fu Ling, poria/Indianbread containing Hydroxyls in abundance
Gan Cao
Gan Cao / Licorice, holder of quinolones in abundance











A large number of formulas in the Shang Han Lun (treatment of Cold Damage), the world’s first medical textbook for colds and flus, contain this Dui Yao pair. It is recommended therefore that you obtain raw versions of this herb, and contact us and learn how to cook it, so you are prepared. Conversely we can also help you get the patent formulas in which it is already prepared.

As we expect, modified classic formulas keep providing excellent treatment options in the modern era, and there is a syncretic way their ancient science can be verified and used. When the ancient made this Dui Yao pair (Zhong Zongjing was the doctor’s name) in the 200s AD or thereabouts, there was no knowledge of modern systematic chemistry. But there was of pattern recognition and symptom treatment.  As I have said elsewhere, “Chinese Solutions for Chinese Problems.”

Thank you for reading, and I hope you are able to take a preventative or if needed a prophylactic treatment, in anticipation of the cure you seek (drug or vaccine). Why wait and live in fear?
