Recent Research Shows the Power of Chinese Medicine


Yu Ping Feng San (YPFS), also known as "Jade Windscreen", is an ancient Chinese herbal formula used for reinforcing the body’s immune defense functions.

Recent research supports YPFS' immunity boosting effectiveness and provides a better understanding of how it protects the body against pathogens.

  • According to this published study by The Hong Kong University of Science and Technology, the combined herbs in YPFS tend to be very effective in warding off airborne pathogens common during cold season. [1]
  • Chinese authorities relied on YPFS (to help boost immunity) during the 2003 outbreak of SARS across China and Hong Kong to help boost immunity. [2]
  • Clinically, YPFS has been applied in anti-viral and anti-bacterial situations and has been shown to prevent viral infections, such as SARS, and to enhance cellular immunity. [1]



Here at DAO Labs we created our Immunity Support formula by starting with Yu Ping Feng San (YPFS) and then adding other ingredients like pear and ginger flavors to create an easy-to-drink effervescent powdered solution.

It's an all-natural alternative to those other supplement powders you're already familiar with, but backed by the power and history of Chinese herbs. This incredible formula will boost immunity when you need it most  - from cold & pollen seasons, to just before boarding your next flight.  

Simply add the powder to water, stir and enjoy. All of our formulas come in individual packets making it easy for you to enjoy at home or on-the-go.  



"I was always getting colds in every season until a friend recommended this product. Since taking I've hardly had a sniffle. I take it at least every other day, it's natural ingredients and tastes good. You'll be pleased with your purchase. "

"I took this through the winter and never had a cold so I continued in spring to address allergies, no itchy eyes or runny nose. Really appreciated finding this product! Thank you."

"Two definitely positive impacts from using Immunity Support include:
1. During the school year, it has built "a screen" around me to protect me from elementary school students' coughs and sneezes.
2. During vacation time, it has screened out the impurities of "airplane air". My attitude towards Jade Windscreen (Immunity Support) is when going out to work or play, 'Don't leave home without it!' "
-- Tamara G.
