About this Episode
Today weâre talking about the innate immune system, the inflammatory response, and the cytokine storm, particularly in the context of pathogenic infections and the role of herbs like echinacea, astragalus, and Andrographis.
What is the role of cytokines in the immune system (01:38)?
There are two main parts to any immune response: 1) the preliminary, non-specific, innate response and 2) the specific, adaptive response involving T cells, B cells, and antibodies that follows.
During the innate immune response, immune cells âpresentâ detected pathogenic material, and cytokines serve the purpose of alerting immune cells if this material is further deemed a threat. Cytokines are the âlanguageâ of the immune system, and any defense system needs a vessel for carrying messages so that the defenders know what the plan of attack is. If pathogenic material is detected, the innate inflammatory response involves recruiting immune cells to the infection site to begin targeting the pathogen.
The takeaway? Cytokines arenât always âthe bad guyâ (03:25). Inflammation isnât always a âbad thingâ (05:10).
What is the cytokine storm (6:04)?
The cytokine storm describes an excessive level of pro-inflammatory cytokines that initiate widespread tissue damage via inflammation. The cytokine storm occurs as a late-stage response to an infection when the infection is not being properly controlled (08:12).
Other notes about the cytokine storm:
- First recognized as a term in 1993, also known as âsepsis,â âtoxic shock syndrome,” âauto-toxicityâ
- Makes infections more severe but is NOT equivalent to an âoverreactionâ of the immune system (09:58)
- Prevent the cytokine storm by enhancing the efficiency of the immune response in early stages of the infection so that pathogen-mediated damage doesnât escalate to the point where cytokine storm ensues (10:16)
Herbs and Their Benefits

Professor Bone’s bottom line (40:48):
The best way to avoid cytokine storm and protect yourself from pathogenic infection is to be as healthy as possible and by supporting the immune system and overall health though diet, supplements, and herbs: âlook at the whole situation.â
