The Common Cold and Prevention

Welcome to another blog connecting research, herbs and good health! Today, we will briefly discuss a research study into two of ViraDefend’s herbs: andrographs and Siberian ginseng. In a study published in 1997 that can be found on Pubmed here: https://www.ncbi.nlm.nih.gov/pubmed/23195395, this powerful herbal combination was found to DOUBLE the chances that school aged children could avoid catching a cold. Here is the breakdown:

  • The design was a randomized placebo-controlled double-blind study (neither the patients nor the clinicians knew which students were getting real herbs or which were getting a fake placebo). This study design is considered the gold standard for clinical studies.
  • After 3 months of taking a combination of andrographis and Siberian ginseng extract at 200mg per day, children had a 30% incidence of catching a cold.
  • After 3 months of taking a placebo (a tablet with no herbs in it), children had a 62% incidence of catching a common cold.
  • That means the children taking the herbs were less than half as likely to catch a cold than those who weren’t.
  • The study used 200mg extract of the herbs per day. ViraDefend contains 600mg extract of these herbs in a single dose.

We have chosen these herbs to include in ViraDefend, like every other herb in ViraDefend, because of research like this, and strong clinical trends seen in our own herbal medicine practice. Please join us for future blogs and more research into the healing power of nature’s pharmacy.
