Spring Flu Prevention Herb Formula from China

We recently received this Flu Prevention herb formula from a contact in China. Some TCM doctors are using this preventative herb formula to protect against contracting the Coronavirus when working in their clinics.

Although I cannot personally vouch for the effectiveness of this formula vis a vis the Coronavirus, it makes sense theoretically, and is similar to other formulas that are commonly used for flu prevention, particularly in the Spring when germs, viruses and bugs begin to flourish as the weather becomes warmer.

The tea and fumigation below are for prevention. If an individual  contracts a flu, and wishes to pursue treatment with traditional Chinese medicine, then they need a formula that is based on differential diagnosis of the signs and symptoms as they manifest in that individual. Hence, they should should see a licensed practitioner of traditional Chinese medicine, rather than using the herb formulas discussed below.

Spring Flu Prevention Tea

Taking this formula as a tea can help the body resist disease by boosting the Wei Qi, and clearing heat, toxicity, damp and phlegm. The tea clears heat from the lungs, and helps regulate the Qi Dynamic. This formula is an aid, not a magic bullet. One should still observe normal flu prevention procedures:

  • Avoid close contact with people who are sick.
  • Avoid touching your eyes, nose, and mouth.
  • Stay home when you are sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
  • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.

The instructions below are for raw herbs, but one could also use granular extracts.

Spring Flu Prevention Formula Ingredients

Flu Prevention Room Fumigation

Another approach to preventing the flu from spreading in your home or office is to fumigate the room with herbs that have anti-viral effects. Use equal amounts of the following herbs. All of these herbs have been shown to have anti-viral properties, and Guan Chong has an extremely inhibitory effect on epidemic influenza virus.

  • 15 Grams 板藍根 Ban Lan Gen (Istatis Root)

Put the herbs in a pot and bring to boil. Lower the flame and let the steam mist the room as you cook the herbs for 40 minutes. Then take the pot off the stove and place it where the steam will fill the room.
